Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Ensure the vehicle is on a level surface and properly supported with jack stands.

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel assembly.
Remove the sensor mounting bolts using a socket set.
Carefully disconnect the electrical connector from the sensor.
Remove the old sensor from the mounting hole and clean the area.
Install the new ABS wheel speed sensor by reversing the removal steps.
- Ensure the sensor is seated properly.
- Torque the mounting bolts to the manufacturer's specifications (usually around 8-10 ft-lbs).
Reconnect the electrical connector securely.

3. Check and Replace ABS Fuse if Necessary

Locate the fuse box and find the ABS fuse (refer to the owner’s manual for exact location).
Remove the fuse and inspect it for any signs of damage.
If the fuse is blown, replace it with a new one of the same amperage rating.
Reinstall the fuse and ensure it is seated properly.

4. Reconnect Battery and Reset ABS Light

Reconnect the vehicle battery terminals.
Use the OBD-II scanner to clear any ABS fault codes.
Start the vehicle and check if the ABS light remains off.
