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 network connection to the RCM. The RCM shares the HS-CAN network with the PCM, the power steering control module, the ABS module, the four-wheel drive (4WD) control module, the occupant classification sensor (OCS) module and the instrument cluster. Voltage for the RCM is provided by circuit CBP32 (GN/VT), and the RCM is case grounded.

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