J1587 and J1708 are essentially the same data bus protocol. The J1587 MID identifying all Bulkhead Information Module faults is 164. Failure Mode Indicator (FMI)–Indicates in what way the function failed.Fault Code Information The information below contains all proprietary Bulkhead Module (BHM) fault codes for J1587 and J1939 data bus protocols. J1587 fault codes consist of the following. The mode/reset switch is used to scroll through the displays on the message display screen. • • • Source Address (SA)–Identifies which ECU the fault is coming from. pin A. The fault codes can be seen on the instrument cluster. See Table 3.A (beginning with SID 050 in Table 1) indicate that the fault is sensed to be coming from the Bulkhead Module. CHM indicates the Chassis Module. All J1939 SPNs for the BHM are listed in Table 2. as described below. • • • Module Identifier (MID)–Identifies which Electronic Control Unit (ECU) the fault is coming from. and EXM1-5 indicates the first through fifth Expansion Module on a vehicle. Each fault code contains three distinct pieces of information. Failure Mode Indicator (FMI)–Indicates in what way the function failed. J1939 faults consist of the following. J1939 SPNs used for diagnostic messages could change when the Bulkhead Module part changes. Suspect Parameter Number (SPN)–Indicates what function on the ECU has failed.
