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 high speed controller area network (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 instrument cluster (IC) and the vehicle dynamics module (VDM). Voltage for the ABS module is provided by circuits 1003 (GY/YE), 483 (RD) and 601 (LB/PK) and ground is provided by circuit 57 (BK).

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