PINPOINT TEST F: THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE WITHOUT ROLL STABILITY CONTROL DOES NOT RESPOND TO THE SCAN TOOL

F1:

F2-F4:

NOTE: Vehicles equipped with roll stability control will communicate on the high speed controller area network (HS-CAN). Standard ABS module vehicles will communicate on the International Standards Organization (ISO) network.

Normal Operation
The ABS module communicates with the scan tool through circuit 70 (LB/WH). The ABS module shares the ISO 9141 network with the parking aid module (if equipped) and the restraints control module (RCM). Voltage for the ABS module is provided by circuit 601 (LB/PK). Circuit 530 (LG/YE) provides ground.

Possible Causes
- Fuse
- Circuit 70 (LB/WH) open, short to ground or voltage
- Circuit 530 (LG/YE) open
- Circuit 601 (LB/PK) open
- ABS module
