Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Clean or Replace ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel hub.
Remove the sensor by unscrewing or unclipping it from its mount.
Clean the sensor tip and the area around it with brake cleaner.
If damaged, replace the sensor with a new one by reversing the removal process.

4. Inspect ABS Module Wiring

Check the wiring harness connected to the ABS module for any visible signs of wear or damage.
Use a multimeter to test the continuity of the wires.
Repair or replace any damaged wires or connectors.

5. Refill Brake Fluid (if necessary)

Check the brake fluid reservoir for proper fluid level.
If low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
Do not overfill the reservoir.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any ABS-related trouble codes.
Test the system to ensure the ABS light does not return.
