Normal Operation
The RCM communicates with the scan tool through the International Standards Organization (ISO) 9141 communication network. Circuit 70 (LB/WH) provides the network connection to the RCM. The RCM shares the ISO network with the parking aid module (if equipped). Voltage for the RCM is provided by circuit 937 (RD/WH). Circuit 1203 (BK/LB) provides ground.

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