General Information
This service bulletin contains information on all proprietary Bulkhead Module (BHM) fault codes for J1587 and
J1939 data bus protocols, how to view these codes, and what they mean. Each fault code contains three distinct pieces of information, as described below.
NOTE: References such as BHM B1.A (beginning with SID 050 in Table 1) indicate that the fault is
sensed to be coming from the Bulkhead Module, connector B1, pin A. Similarly, CHM indicates the
Chassis Module, and EXM1-5 indicates the first through fifth Expansion Modules on a vehicle.
J1587 fault codes consist of the following, in this order:
• Module Identifier (MID) – Identifies which Electronic Control Unit (ECU) the fault is coming from. The
J1587 MID identifying all Bulkhead Information Module faults is 164.
• Subsystem Identifier (SID) – Indicates what function on the ECU has failed. All J1587 SIDs for the BHM
are listed in Table 1.
• Failure Mode Indicator (FMI) – Indicates in what way the function failed.
J1939 faults consist of the following, in this order:
• Source Address (SA) – Identifies which ECU the fault is coming from. The J1939 SA identifying all Bulkhead Module faults is 33.
• Suspect Parameter Number (SPN) – Indicates what function on the ECU has failed. All J1939 SPNs for
the BHM are listed in Table 2.
• Failure Mode Indicator (FMI) – Indicates in what way the function failed.
Also included is a reference table of all FMIs for both data bus protocols. See Table 3.
NOTE: In ServiceLink, J1587 fault codes are shown under J1708. J1587 and J1708 are essentially
the same data bus protocol.
NOTE: As the SAE J1939 subcommittee approves new SPNs for use in J1939 messaging on a continual basis, J1939 SPNs used for diagnostic messages could change when the Bulkhead Module
part changes. These changes could impact any diagnostic message with an SPN value of 6915 or
higher.

Viewing Faults in ServiceLink
Both J1587 and J1939 fault codes can be viewed in ServiceLink. Only J1587 fault codes can be viewed on the
instrument cluster. J1939 fault codes CANNOT be viewed on the instrument cluster.
To view fault codes using ServiceLink:
1. Connect to the vehicle using an approved communication device.
2. Open ServiceLink in either online or offline mode.
3. Turn the vehicle’s ignition to the ON position.
4. Click on the Connect button in ServiceLink.
NOTE: The J1587 Message Identifier (MID) for the BHM is 164, and the J1939 Source Address (SA)
for the BHM is 33, shown in the far left column of the main window in Fig. 1, and Fig. 2.
5. From this point, either:
• Click on the Faults tab from the main ECU List screen to display all faults present on the vehicle. See
Fig. 1. Or,
• Click on the Bulkhead Module icon first, then on the Faults tab to display faults coming from the BHM
only. See Fig. 2.
Viewing J1587 Faults on the Instrument Cluster
While fault codes for both data bus protocols (J1939 and J1587) can be viewed using ServiceLink while connected to the vehicle, only J1587 faults can also be viewed on the dash message center of the ICU3-M2 instrument cluster. See Section 54.04, Subject 410 of the Business Class® M2 Workshop Manual for Mode/Reset
Switch Functions and how to use the mode/reset switch on the ICU3-M2 to display fault information.
The following is one example using the ICU3-M2 dash message center to view a J1587 fault.
1. In this example, during an active fault the first screen shows "SYS 164". See Fig. 3. This indicates the fault
is coming from the BHM, which has a J1587 MID of 164.
NOTE: The Bulkhead Module (BHM) will appear on the dash message center as "SYS 164." Be
aware that the "SYS" looks like the numbers "545" on the digital display, as shown in Fig. 3.
2. Pressing the mode/reset switch displays the second fault screen, which shows "SID 022". See Fig. 4.
3. Next, find the description for SID 22 in Table 1, which lists the description as "Missing Smart Switch."
4. Press the mode/reset button again and the third ICU screen displays "Fail 07". See Fig. 5.
5. Next, find FMI 07 in in the J1587 Description column. See Table 3. It indicates "Mechanical system not responding properly."
In this example, the fault indicates that the mechanical system is not responding properly because the BHM
senses that a Smart Switch is missing from the vehicle. There can be various possibilities for the cause of
each fault.
