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 Conditions

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 .

AR1 CHECK CAN (CONTROLLER AREA NETWORK) DATA

A DTC has been set which has the following description:
- Invalid Data Received From SODCMD Control Module

Ignition ON.

Clear the ABS DTCs.

Ignition OFF.

Ignition ON.

Wait at least 1 minute.

Using a diagnostic scan tool, retrieve all DTCs from the ABS module. NOTE: DTCs may be displayed from previous diagnostic actions.

Did the DTCs return?

Yes	Invalid or Missing CAN Data From the SODCMD. Check the CAN bus and terminating resistor (60 ohm) at the OBD connector. Check CAN bus circuit. Check for other failures in the SODCMD Control Module. Notice: Do not replace the ABS module.

No	Return the vehicle to the customer. If the fault reoccurs inform the customer to note any relevant conditions at the time of the fault. The test is now exiting.
