Normal Operation
The RCM communicates with the scan tool through the International Standards Organization (ISO) 9141 communications network, circuit 70 (LB/WH). The RCM shares the ISO 9141 network with the parking aid module (if equipped) and the anti-lock brake system (ABS) module without roll stability control (if equipped). Voltage for the RCM is provided by circuit 937 (RD/WH). Ground is provided by circuit 1203 (BK/LB).

Possible Causes
- Fuse
- Circuit 70 (LB/WH) open
- Circuit 937 (RD/WH) open
- Circuit 1203 (BK/LB) open
- RCM
