Anti-Lock Brake System (ABS) Module

The ABS module uses the high speed CAN for communication with the diagnostic tool and other modules on the high speed CAN. The ABS module controls the brake pressure to the 4 wheels to keep the vehicle under control while braking.

Check the high speed CAN circuits between the ABS module C135 and the 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 circuit in the high speed CAN, damage to the DLC C251, damage to the ABS module C135, or a problem in the in-line connector.
