Pinpoint Test Ar: Abs (Anti-Lock Brake System) Module Communication Concern With The SODCMD (Side Obstacle Detection Control Module D)
- Refer to Horn/Cigar Lighter
for schematic and connector information.
Normal Operation and Fault ConditionsÂ
With the ignition ON, the SODCMD module sends messages to the ABS module over the MS-CAN. If the ABS module does not receive these messages within the allotted time frame or if the messages contain invalid data, the module sets a DTC. This can be due to a SODCMD module failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the SODCMD, refer to Network Message Charts .
