Test G: The Power Steering Control Module Does Not Respond To The Scan Tool

PINPOINT TEST G: THE POWER STEERING CONTROL MODULE DOES NOT RESPOND TO THE SCAN TOOL

Normal Operation
The power steering control module 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 power steering control module. The power steering control module shares the HS-CAN network with the PCM, the ABS module, the restraints control module (RCM), the occupant classification sensor (OCS) module, the four wheel drive (4WD) control module and the instrument cluster. Voltage for the power steering control module is provided by circuits SBP13 (GY/RD) and CBP35 (YE/GY) and circuit GD148 (BK/YE) provides ground.

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