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 9141 network with the fire suppression module (if equipped). Voltage for the RCM is provided by circuit 937 (RD/WH). Circuit 676 (PK/OG) provides ground.

Possible Causes
- Fuse
- Circuit 70 (LB/WH) open
- Circuit 676 (PK/OG) open
- Circuit 937 (RD/WH) open
- RCM
