Solution

1. Preparation

Gather the necessary tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean ABS Wheel Speed Sensors

Tools Required: Socket set, torque wrench, wire brush
Remove the wheel associated with the ABS light.
Locate the ABS wheel speed sensor on the brake assembly.
Clean the sensor and the mounting area with a wire brush to remove dirt and debris.
Reinstall the sensor and torque to manufacturer specifications.

3. Check and Replace ABS Fuse (if necessary)

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box and identify the ABS fuse.
Remove the fuse and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

4. Repair or Replace Faulty Wheel Speed Sensors

Tools Required: Socket set, multimeter
If the wheel speed sensors are damaged, disconnect the electrical connector and remove the sensor.
Use a multimeter to test the sensor's resistance; replace if it is out of specification.
Install the new sensor, ensuring a proper fit and secure connection.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains illuminated.
Perform a test drive to confirm that the ABS functionality is restored.
