Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is on a level surface and securely supported.

2. Inspect ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
Disconnect the electrical connector from each sensor.
Use a multimeter to test the sensor resistance; compare with manufacturer specifications.
Replace any faulty sensors.

3. Check ABS Module and Wiring

Remove the ABS module cover if accessible.
Inspect the wiring for any frayed or damaged insulation.
Use a multimeter to check for continuity in the wiring.
Repair or replace any damaged wiring as necessary.

4. Replace ABS Fuse

Locate the fuse box and identify the ABS fuse (refer to owner’s manual for location).
Use a fuse puller to remove the fuse.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

5. Refill Brake Fluid and Bleed Brakes

Check the brake fluid level; if low, add the correct type of brake fluid (DOT 3 or DOT 4 as specified).
If air is suspected in the brake lines, bleed the brakes using the two-person method or a vacuum bleeder.
Ensure the brake fluid is clean and at the recommended level.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains illuminated.
Conduct a test drive to verify proper functioning of the ABS system.
