Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to ensure electrical safety.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the “ON” position without starting the engine.
Retrieve and document any ABS-related error codes.

3. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors on each wheel.
Disconnect the electrical connector from each sensor.
Remove the mounting bolt and carefully extract the sensor from its housing.
Inspect the sensor for damage; replace if necessary.
Reinstall the new sensor, ensuring it is properly seated and secured.

4. Repair or Replace Wiring Harness

Inspect the ABS wiring harness for any visible damage or corrosion.
If found, repair the damaged sections using appropriate wire repair techniques.
For severe damage, replace the entire wiring harness with an OEM part.

5. Replace ABS Module (if necessary)

Disconnect the electrical connectors from the ABS module.
Remove the mounting bolts securing the ABS module to the vehicle.
Carefully extract the module from its position.
Install the new module in reverse order, ensuring all connectors are securely attached.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Turn the ignition on and check if the ABS warning light is still illuminated.
