Test C: The Anti-Lock Brake System (ABS) Module Does Not Respond To The Diagnostic Tool

PINPOINT TEST C: THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

C1:

C2-C3:

Normal Operation
The ABS module communicates with the diagnostic tool through the controller area network (CAN) circuits 1827 (WH/LG) and 1828 (PK/LG). Check the CAN circuits between the ABS module C135 and the data link connector (DLC) C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open in the CAN circuits, damage to the DLC C251, damage to the ABS module C135, or a problem in the in-line connectors.

Possible Causes
- CAN data plus circuit 1827 (WH/LG) open
- CAN data minus circuit 1828 (PK/LG) open
- ABS module C135
- ABS module
