Test G: The Steering Angle Sensor Module (SASM) Does Not Respond To The Scan Tool

PINPOINT TEST G: THE STEERING ANGLE SENSOR MODULE (SASM) DOES NOT RESPOND TO THE SCAN TOOL

Normal Operation
The steering angle sensor module (SASM) 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 SASM. The SASM shares the HS-CAN with the PCM, the ABS module, the 4X4 control module (if equipped), the restraints control module (RCM), the occupant classification system module (OCSM), the accessory protocol interface module (APIM), the headlamp control module (HCM) (if equipped) and the instrument cluster (IC). Voltage to the SASM is supplied by circuit CBP34 (VT/BN). Ground is supplied by circuit GD115 (BK/GY).

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