Test F: The Anti-Lock Brake System (ABS) Module Does Not Respond To The Diagnostic Tool
PINPOINT TEST F: THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOLF1-F3:
Normal Operation
The ABS module communicates with the diagnostic tool through the controller area network (CAN) circuits 1908 (WH) and 1909 (BK). Check the CAN circuits between the ABS module C155 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 C155, or a problem in the in-line connectors.
Possible Causes
- CAN circuits 1908 (WH) or 1909 (BK) open
- ABS module C155
- ABS module
