Test B: The ABS Module Does Not Respond To The Scan Tool

PINPOINT TEST B: THE ABS MODULE DOES NOT RESPOND TO THE SCAN TOOL

Normal Operation
The ABS module communicates with the scan tool through the HS-CAN. Circuits 1827 (WH/LG) (HS-CAN +) and 1828 (PK/LG) (HS-CAN -) provide the network connection to the ABS module. The ABS module shares the HS-CAN with the PCM, the restraints control module (RCM) and the instrument cluster (IC). Voltage for the ABS module is provided by circuit 640 (RD/YE). Circuit 530 (LG/YE) provides ground.

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