Escape 4WD V6-3.0L (2008)
D5
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
