Test C: The Restraints Control Module (RCM) Does Not Respond to the Scan Tool
PINPOINT TEST C: 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 module shares the HS-CAN with the PCM, the 4X4 control
module, the occupant classification system module (OCSM), the SJB, and the instrument cluster (IC). Voltage for the RCM is provided by circuit
CBP08 (GY/YE), and the RCM is case grounded.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Case ground open
-
RCM
