Test K: The Restraints Control Module (RCM) Does Not Respond To The Scan Tool

PINPOINT TEST K: THE RESTRAINTS CONTROL MODULE (RCM) DOES NOT RESPOND TO THE SCAN TOOL

Normal Operation
The RCM communicates with the scan tool through the International Standards Organization (ISO) 9141 network. Circuit 70 (LB/WH) provides the network connection to the RCM. The RCM shares the ISO 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.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
