Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Anti-Lock Brake System (ABS) Module
The ABS module uses the CAN for communication with the diagnostic tool and other modules on the CAN. The ABS module controls the brake pressure to the 4 wheels to keep the vehicle under control while braking. The ABS module and the instrument cluster share CAN termination responsibilities with the use of a split termination resistor in each module.
Check the 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 CAN, damage to the DLC C251, damage to the ABS module C135, or a problem in the in-line connector.
