Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery before starting work on the ABS system.
Ensure the vehicle is on a flat surface and securely supported.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the wheel and brake components as necessary to access the sensors.
Disconnect the electrical connector from the sensor.
Remove the sensor using the appropriate socket or wrench.
Inspect the old sensor for damage; replace with a new sensor if faulty.
Reverse the removal steps to install the new sensor, ensuring it is seated properly.

3. Repair Wiring Issues

If any damaged wiring is found during inspection, cut out the damaged section.
Strip back insulation and twist the wires together.
Solder the connection and cover with heat-shrink tubing or electrical tape.
Ensure all connections are secure and protected from moisture.

4. Replace ABS Module (if necessary)

Disconnect the battery again.
Locate the ABS module, typically near the brake master cylinder.
Remove any associated covers or brackets.
Disconnect electrical connectors from the module.
Remove the mounting bolts securing the module to the chassis.
Install the new ABS module by reversing the removal steps, ensuring all connectors are fully engaged.

5. Reconnect Battery and Clear Codes

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any stored error codes in the ABS module.
Start the vehicle and check for the ABS warning light.
