Chapter 3 Introduction to Multiplexing The multiplexed electrical system replaces the traditional power distribution module (PDM) devices, such as relays and circuit breakers, with electronic devices that communicate over the vehicle datalink. Multiplexing occurs when two or more distinct signals or messages are transmitted at the same time. The Multiplexed electrical system is able to simultaneously perform tasks and to monitor components. A multiplexed system uses Electronic Control Units (ECUs) to operate the various systems on the vehicle, such as lights, brakes, wipers, displays, gauges, and so on. The electrical system components, such as switches and lamps, are connected to the ECUs, which collect and control all of the information about the components by communicating over a datalink. The Freightliner Business Class M2, Thomas Built Bus C2, and the Freightliner Cascadia are examples of vehicles with a multiplexed electrical system. This chapter contains the following information: ■

Different Multiplexed Electrical System ECUs The multiplexed electrical system for the Freightliner Business Class M2 and the Thomas Built Bus C2 differs from the Cascadia multiplexed system. M2 and C2 ECUs In an M2 or C2 multiplexed electrical system, the Bulkhead Module (BHM) is the brain of the electrical system. It controls the Chassis Module (CHM) and Expansion Module (EXM). The BHM uses the J1939 protocol for primary diagnostics instead of the J1708 protocol, which is secondary and is used for limited troubleshooting. Depending on the vehicle, the multiplexed electrical system ECUs listed in the following table are available. ECU

Description

BulkHead Module (BHM)

The primary ECU that controls the electrical and power distribution system. The BHM is programmed to know which output it should activate for a certain input and where the output is located (on the BHM, CHM, SHM, EXM, or other controller). Use the BHM as the main source of information for troubleshooting. A vehicle has one BHM. Click the BHM icon to view the general information, faults, configuration, features, software updates, and templates for each connected protocol.

Chassis Module (CHM)

A secondary ECU that works with the BHM. It responds to commands from the BHM and communicates the status of the input (such as switches) and output (such as lights) that are connected to it. A vehicle has one CHM. Click the CHM icon to view the general information, faults, configuration, and templates. You can find J1939 and J1708 CHM faults on the BHM Faults window. The generic J1708 CHM faults are included in the CHM Faults window.

ServiceLink Guide

ECU

Description

Expansion Module(s)

An optional ECU that functions like the CHM. The EXM is used to

(EXM)

extend the functionality of a CHM when additional input and output are required. The EXM responds to commands from the BHM and communicates the input (such as switches) and output (such as lights) that are connected to it. A vehicle may have from zero to five EXMs. Each EXM on the vehicle appears on the sidebar. When adding an EXM to the vehicle, you can override the size recommendation to a larger size. After an EXM is installed, it cannot be replaced with a different size. Click the EXM icon to view the general information, faults, configuration, and templates. You can find J1939 and 1708 EXM faults on the BHM Faults window. The generic J1708 EXM faults are included in the EXM Faults window.

Switch Hub Module (SHM)

A secondary ECU that works with the BHM and is only available on C2 vehicles. The SHM responds to commands from the BHM and communicates the status of up to 24 smart switches as inputs. It controls any outputs (such as lights, relays, the stop sign that swings out, and so on) that are connected to it. A vehicle has only one SHM. An 8-switch bank s the placement and the electrical connection of up to eight smart switches to the SHM. Click the SHM icon to view the general, faults, templates, configuration, smart switches, and flashing information. You can view some of the J1939 and J1708 faults on the SHM Faults window. The BHM also reports some of the J1939 and J1708 faults for the SHM, which can be viewed in the BHM Faults window.

Switch Expansion

An optional ECU that operates smart switch inputs. Up to six smart

Module(s) (SEM)

switches can be added practically anywhere in the cab. The SEM does not control any outputs, but responds to commands from the BHM and communicates the inputs (such as switches) that are connected to it. A vehicle may have from zero to four SEMs. Each SEM appears on the sidebar. Click the SEM icon to view the general, faults, templates, smart switches, and flashing information. You can view some of the J1939 faults on the SEM Faults window. The BHM reports smart switch faults that may involve the SEM in the BHM Faults window.

Introduction to Multiplexing

Cabin Controller Area Network ECUs The Cascadia multiplexed system uses four main ECUs along with various other ECUs. These four main ECUs reside on the Cabin Controller Area Network (CAN) datalink. The Cabin CAN datalink does not have a direct connection to the diagnostic connector. Therefore, off-board tools such as ServiceLink troubleshoot and configure these Cabin CAN ECUs by connecting to the Diagnostic CAN datalink pins in the diagnostic connector (refer to the illustration “Diagnostic connector pinout” on page 16). The Diagnostic CAN datalink connects ServiceLink to the Central Gateway (CGW) ECU. Via the CGW, ServiceLink uses the Controller Area Network (CAN) communication protocol to communicate with the Cabin CAN ECUs. This is similar to how J1587 is the communication protocol to communicate with ECUs physically connected to the J1708 datalink. Depending on the vehicle, the CAN multiplexed electrical system ECUs for the Cascadia are listed in the following table: ECU Central Gateway (CGW)

Description The primary function of the CGW is to connect the different datalink networks on the vehicle, and to route and translate the datalink messages between them. The CGW also performs the following functions: ■

Interfaces between off-board tools and Cabin CAN ECUs

■

Monitors for missing ECUs on the Cabin CAN datalink. Each missing ECU is described in a CAN fault code generated by the CGW.

The Central Gateway reports CAN ECU faults and can have its software reprogrammed (flashed) to its same version or upgraded, if required, using ServiceLink. The Central Gateway does not have any parameters to configure. Signal detection and

Chassis

The SAM Chassis reports CAN ECU faults and can have its software reprogrammed (flashed) to its same version or upgraded, if required, using ServiceLink. Parameters can be configured for the Sam Chassis, if required, using ServiceLink.

Modular Switch Field

The modular switch field is made up of a master module (including

(MSF)

the Hazard light switch), slave s, and various connected switches. Only the master module is directly connected to the Cabin CAN datalink and is seen in ServiceLink as MSF. The MSF controls the cab switches including sub-bus switches (multiplexed and hard-wired), steering-wheel switches, the rotary switch (also known as the head lamp switch), and stalk switch. The MSF’s sub-bus switches have some similarities to the M2 “Smart Switches,” but the sub-bus switches are different. The MSF’s sub-bus switches can be viewed on the MSF’s Switches window. See “View MSF Switches on Vehicles” on page 107 for more information. The MSF reports CAN ECU faults and can have its software reprogrammed (flashed) to its same version or upgraded, if required, using ServiceLink. Parameters can be configured for the MSF, if required, using ServiceLink. Sub-bus switches connected to the vehicle and the position of any signal switch can be viewed.

Role of the Host In a multiplexed electrical system, the host plays a more active role in the diagnosis and repair of vehicle problems within ServiceLink. For example, when installing a new version of the BHM, the ServiceLink Sync ECU List to Host function migrates the Reference Parameter Numbers (RPNs) for the updated version of the BHM. For CAN ECUs, information stored on the Host includes the CAN ECU's general information, parameters, and Flashing information. It is recommended that you work in online and connected mode. This is the easiest method of working on multiplexed systems because it provides full functionality.

Clear the historic faults for a specific ECU Historic faults are faults that were active at one time in the past, but have become inactive. Historic faults are listed because the problem is intermittent, or the fault was repaired but not cleared from the ECU memory. Faults are displayed in real time with an automatic refresh within two seconds of a state change. ti p: Historic faults are your starting point for identifying intermittent ★ problems. Clear historic faults after you repair a problem, especially if it’s an intermittent problem.

To view and clear the historic faults for a specific ECU: 1. Click a specific ECU device on the sidebar. The General Info window appears. 2. Click the Faults tab.

Faults from some ECUs, such as CAT, Cummins, and Detroit engines and Wabco ABS, can be viewed but not cleared. View the fault information for B2 and C2 multiplexed system ECUs Fault information is available for each multiplexed system ECU. However, because the Bulkhead Module (BHM) is the controller of the B2 and C2 multiplexed system units, the key fault information is found in the BHM Faults display. The Switch Hub Module (SHM) and Switch Expansion Module (SEM) display some of their own faults. The following table provides a breakdown of where to find fault information for multiplexed system ECUs. Multiplexed System ECU

Fault Display Information

Bulkhead Module (BHM)

Displays circuit-based fault information for the BHM, SHM (C2 only), CHM, and any EXMs. The J1708 BHM faults table lists pin-based fault information for the J1708 BHM and CHM. The BHM reports J1708 EXM faults as a generic module fault message.

Chassis Module (CHM)

Currently, no J1939 faults appear in the CHM ECU windows. Go to the BHM ECU window to view the CHM J1939 faults. The J1708 pin-based and generic fault information for the CHM appears in the J1708 BHM faults table. Currently, the CHM reports J1708 generic module faults, but most of the faults are listed in the BHM J1708 faults table.

Currently, no J1939 faults appear in the EXM ECU windows. Go to the BHM ECU window to view the EXM J1939 faults. Currently, the EXM includes J1708 generic module faults, but most of the faults are listed in the BHM J1708 faults table.

Switch Hub Module (SHM)

Some J1939 and J1708 faults appear in the SHM faults table, while other J1939 and J1708 faults appear in the BHM faults table. Check both ECU fault tables.

Switch Expansion Module

Some J1939 appear in the SEM faults table. Smart Switch faults that

(SEM)

may involve the SEM are listed in the BHM ECU faults table.

View and clear fault information for CAN ECUs ServiceLink looks up and displays descriptions for CAN suspect parameter names (SPNs) and failure mode indicators (FMIs). ServiceLink performs additional checks for CAN faults because they operate differently from J1708 or J1939 faults. Some faults from CAN ECUs may appear in grey text when you select the J1708 and J1939 protocols. However, you must select the CAN protocol to view all of the faults to troubleshoot the CAN ECUs. ServiceLink displays CAN ECU new fault information in real time just as it does other ECU faults. The steps you take to clear CAN faults is the same. Even though ServiceLink clears both active and historic CAN faults, note that ServiceLink clears only historic faults for J1939 and J1708. If fault conditions are still present on the vehicle, active CAN faults will reappear after being cleared.

Gain Access to Templates from the ECU List The list for each connected protocol contains all of the available templates that correspond to the vehicle ECUs on the ECU List window. A template corresponds to one or more ECUs based on their Message Identifier/Source Address/ECU identification (MID/SA/ECU ID), make, model and software ID. To gain access to a template from the ECU List window: 1. Click the Templates tab. By default, all ECU templates appear in the drop-down lists for connected ✐ note protocols. Select the Display All Templates option to change the selection to view all templates for the connected protocols.

2. Select a template from the drop-down list for a protocol. The template appears in a new window, and includes the information that is specified by the available data on the databus. The template you select stays active until you select another template or another window. You can also choose a template from a specific ECU window. For more ✐ note information, see “Gain Access to Templates from a Specific ECU” on page 54.

Gain Access to Templates from a Specific ECU The list for each connected protocol contains all of the available templates that correspond to the vehicle’s ECU. If no templates are available for a specific ECU, the “No Templates Available” ✐ note message appears on the Templates tab.

To gain access to a template from a specific ECU: 1. Click a specific ECU device on the sidebar. The General Info window appears. 2. Click the Templates tab. By default, all templates for the selected ECU appear in the drop-down ✐ note lists for connected protocols. Select the Display All Templates option to change the selection to view all templates for the connected protocols.

3. Select a template from the drop-down list for a protocol. The template appears in a new window and includes the information specified by the available data on the databus. The template that you select stays active until you select another template or another window.

Gain Access to Multiplexing Templates The Templates window lists all of the DataLink Monitor Templates that are available for the multiplexed electrical system. You can use these templates to monitor and test the input and output of the electrical system. You can also use any of the templates to view and record readings from the ECU sensor inputs. Templates are available for all of the multiplexing ECUs. The multiplexed system units use three types of templates: Template

Description

Pin-based

All of the optional systems on both the M2 and C2 use pin-based templates such as the BHM Connector B1 template. Pin-based templates are available for the BHM, CHM, EXM, SEM, and SHM. Pin-based templates are available for the Cabin CAN ECUs.

Function-based

The BHM and CHM ECUs use function-based templates for most standard functions, such as the Headlamps template. (You do not need to know the pin number associated with these circuits to use these templates.) Function-based templates are available for the Cascadia’s multiplexed system.

Smart Switch

The ECUs that have smart switches connected to them have a special type of template to help with troubleshooting the smart switches. Smart Switch templates are available for the BHM, SEM and SHM ECUs.

Gaining Access to Templates

55

All templates have the following features: ■

Test buttons to enter (start) or exit (stop) the test mode (applies to M2 and C2 templates only)

■

Input buttons that indicate switch positions

■

Buttons to manipulate (on/off positions) output

■

Output that appears either graphically or as values

To gain access to a multiplexing template: 1. Click the Templates tab. By default, all templates for the selected ECU appear in the drop-down ✐ note lists for connected protocols. Select the Display All Templates option to change the selection to view all templates for the connected protocols.

2. Select the template that you want to use. The template appears in a new window and includes the information specified by the available data on the databus. The template that you select stays active until you select another template or another window. The following example shows a template for the Bulkhead Module.

56

ServiceLink Guide

Use Templates to Troubleshoot Smart Switches Smart switch templates differ from the other two types of templates because they are neither pin-based nor function-based. Instead, the templates list the values that are unique to each switch that can be used to troubleshoot smart switches. The BHM smart switch template provides slightly different information than the templates for those switches connected by means of the SEM and SHM. All available smart switch templates show a smart switch’s unique ID value and can be used to test a switch’s indicator light functionality, as well as the ECU’s backlighting functionality. ■

Use the BHM Smart Switches template (see page 57)

■

Use the SEM and SHM Smart Switches templates (see page 57)

Use the BHM Smart Switches template Smart switches connected to the BHM do not display information in the Smart Switch window like the smart switches do that are connected to an SEM or SHM. To troubleshoot the BHM smart switches, use the template titled “Smart Switches” that can be found on the Templates tab. The BHM template reports the unique resistance values for each connected switch. You can use these values to identify a smart switch and to make sure that it is reporting the expected resistance values. The resistance values include ID #1 and ID #2, which are combined to determine the switch’s unique ID value and to indicate the switch’s current input position. Use the SEM and SHM Smart Switches templates In addition to the information on the SEM and SHM Smart Switches windows, templates are available to help troubleshoot the switches that are connected to these ECUs. The SEM and SHM smart switch templates provide slightly different information than the BHM smart switch template. These templates are named by the bank for the SHM or as J2 smart switches for an SEM.

Gaining Access to Templates

57

The SEM and SHM templates list the switch’s current position, as well as the unique values for each connected switch labeled as ID1, ID2, and Position. You can use these values to identify a smart switch and to make sure that it is reporting the expected internal resistance values. To do so, use the worksheet that is attached to the template. There are Smart Switch-type templates available as pin-based templates for the ✐ note SEM (connector J2) and SHM (connectors J5-Bank A, J6-Bank B, and J7-Bank C).

Example Template: Engine Boost Pressure This example uses the Engine Boost Pressure template accessed through the Engine ECU. To gain access to the Engine Boost Pressure template: 1. Click the Templates tab from either the ECU List window or the Engine ECU window. 2. Select the Engine Boost Pressure template from the J1708 protocol drop-down list. The contents of the Engine Boost Pressure template appear. 3. With the engine running, depress the vehicle accelerator. The template window graphically displays values broadcast on the databus. Engine fault codes (active and historic) appear in the fault code window of the template. You can these faults against the engine ECU fault codes. note If an item or window flashes, no data is currently being broadcast on the ✐ databus for that item or window.

View, Change, and Reset CAN ECU Parameters All of the ECUs that are connected to the Cabin CAN datalink, except for the CGW, have parameters that can be configured. Parameters tell the ECU how to control the vehicle. All Cabin CAN ECUs with parameters, such as the MSF, SAM-Cabin, and SAM-Chassis, have the same parameter structure and behavior described in this section. There are two levels of parameters: function parameters and detailed parameters. Each function parameter has one or more detailed parameters describing what the function does (simply called parameters in ServiceLink), such as the following examples: ■

Hardware or software interlocks

■

Cut-off speeds

■

Maximum and minimum limits

■

Sub-bus switch availability (MSF parameters)

Each of the detailed parameters has a certain value. For example, a function parameter, such as a horn, may have a detailed parameter indicating that it uses a foot switch as an input. In a CAN ECU's Parameters window in ServiceLink, parameters are either read-only or viewable and changeable. All changeable parameters have a part number associated with them, just like a hardware part. When adding, removing, or changing a feature, the needed parameters are provided in the form of a part number in the Bill of Material (BOM) obtained for that feature by means of the Aftermarket Parts Desk.

68

ServiceLink Guide

It may be necessary to view, change, or re-apply parameters in the following scenarios: ■

Add an optional feature (such as Daytime Running Lights)

■

Remove an optional feature

■

■

Change the functionality of an existing feature (for example, change the vehicle's Daytime Running Light feature to activate both Marker Lights and Low Beams, instead of activating only Low Beams) Replace the ECU. Reapply the parameters to ensure proper and expected vehicle functionality.

Flashing (or reprogramming) the software is separate from changing the parameters, just as it is in an engine controller. Refer to “Upgrade CAN ECUs” on page 83 for more information. The following parameter functions are available for CAN ECUs. ■

Chapter 12 Identifying Multiplexed Switches The C2 and M2 smart switches have special component functionality specific to the Switch Expansion Modules (SEMs) and Switch Hub Module (SHMs). Each smart switch has a specific function and is assigned a unique ID number. The ID number is determined by the resistance values that are recognized by the connected ECU. The Modular Switch Field (MSF) ECU manages the switches on the Cascadia. There are two types of switches in the Modular Switch Field: sub-bus switches and other MSF switches, such as the hazard and headlamps switches. This chapter contains the following information: ■

Smart Switches on C2 and M2 Vehicles Smart switch descriptions and functionality vary depending on whether the ServiceLink computer is connected to a C2 or M2 vehicle. For example, the Fog Lamps on the M2 vehicle use the switch ID 22, however, on the C2 vehicle the switch ID for Fog Lamps is 315. On M2 vehicles, up to five smart switches can be connected directly to the Bulkhead Module by means of the connector B7. Smart switches can also be connected to the vehicle by means of SEMS, with six smart switches per SEM, and up to four SEMs allowed on a vehicle. For more information, see “Different Multiplexed Electrical System ECUs” on page 22. On C2 vehicles, smart switches are connected to the electrical system by means of BHM and SEMs, and up to 24 smart switches can also be connected by means of a Switch Hub Module (SHM). For more information, see “Different Multiplexed Electrical System ECUs” on page 22.

Smart Switch Window Smart switch information for the SEM and SHM appears in a table that is filtered to list the selected module’s icon at the top. The information is then sorted by module and switch ID. The following information appears on a Smart Switch window: Column Heading

Description

ECU

Indicates whether a switch is connected to an SEM or SHM. For an SHM, the bank of the 8-switch bank that the switch is plugged into is identified (Bank A, Bank B, or Bank C). For an SEM, the SEM number the switch is plugged into is identified. For more information, see “Identify SHM Smart Switches” on page 105 and “Identify SEM Smart Switches” on page 106.

ServiceLink Guide

View MSF Switches on Vehicles The Modular Switch Field (MSF) system comprises of a MSF Master ECU, MSF slave s, and various connected switches. The ECU parameters on the MSF Master determine which switches belong on a particular vehicle. The MSF Master reports various faults for these switches, such as short-circuits to power or ground. There are two types of switches in the MSF system: 1. Sub-bus switches: ❒

❒

Multiplexed switches, also known as Signal-only switches. The MSF Master monitors the sub-bus for a signal switch's presence, as well as its switch position. That switch position (such as up, down, or not pressed) is then provided to other ECUs on the Cabin CAN datalink that use that switch as an input. Hardwired switches, also known as Load-interrupting switches. The MSF Master monitors the sub-bus for a hardwired switch's presence only. The MSF Master does not monitor the switch position of a hardwired switch.

2. Other MSF switches: ❒

Hazard switch

❒

Rotary switch (Headlamps)

❒

Stalk switch

❒

Steering Wheel switches

You can view a list of sub-bus switches that are currently connected to a vehicle, as well as the position of any multiplexed switch, in the Switches window of the MSF icon.

!

caution Be aware that there are switches in the vehicle that may not be part of the Modular Switch Field. Some examples are door switches, switches for mirror direction, ABS check, and possibly other aftermarket switches.

4. Click OK. The older reference parameters are migrated to the new BHM. If the version on the vehicle is incompatible with the version on the host, ✐ annote error message appears indicating that the host could not be updated with the BHM information.

5. After the synchronizing is finished, perform flashing and update the features as necessary to complete the upgrade operation.

Add or Replace a New Switch Expansion Module Unlike other ServiceLink ed devices, the Switch Expansion Modules (SEMs) use a dynamic J1939 addressing system, which means that when a new SEM is added to the vehicle or an existing SEM is replaced, the source addresses of all of the modules on the vehicle could change. Up to four SEMs are allowed on a vehicle. If more than four SEMs are added to a vehicle or if the SEM is unable to claim an address, the SEM broadcasts a message that it is unable to claim an address. An SEM that has an invalid or no application code is listed as an Invalid SEM (Unresponsive) with a J1939 source address of 133 during the roll call. Because of the dynamic addressing for SEMs, the SEMs might be listed in nonsequential order. For example, if a vehicle had three SEMs and one was replaced, the SEMs could display as SEM #1, SEM #2, and SEM #4. Use the Smart Switch window to locate the problem switch or module if the source address changes. Replace an SEM Use the following procedure to replace an SEM. To replace an SEM: 1. Replace the old SEM with the new module. The new SEM takes either the same source address of the module that was replaced or claims a new source address.
