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

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

Normal Operation
The RCM communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits VDB04 (WH/BU) (HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the HS-CAN network connection to the RCM. The RCM shares the HS-CAN network with the PCM, the ABS module, the four wheel drive (4WD) control module, the instrument cluster, the power steering control module and the occupant classification sensor module. For Hybrid vehicles, the instrument cluster also shares the HS-CAN network with the transmission control module (TCM) and traction battery control module (TBCM). Voltage for the RCM is provided by circuits CBP32 (GN/VT) and the RCM is case grounded.

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