Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool if it has been running.

2. Inspect and Test ABS Components

ABS Fuse and Relay Check
- Locate the fuse box and identify the ABS fuse.
- Remove the fuse and check for continuity using a multimeter.
- Replace the fuse if blown.
- Test the relay by swapping it with a similar one in the fuse box.
Brake Fluid Inspection
- Open the master cylinder reservoir cap.
- Check the brake fluid level; add the recommended fluid type if low.
- Inspect the fluid for contamination; replace fluid if it appears dirty.
Wheel Speed Sensor Examination
- Lift the vehicle and remove the wheel for access.
- Inspect the wheel speed sensor for dirt and damage.
- Clean the sensor with brake cleaner and reconnect any loose wiring.
Testing the ABS Module
- Reconnect the battery and use an OBD-II scanner to check for current codes.
- If codes indicate a faulty module, further testing or replacement may be required.
- Check wiring harness for shorts or disconnections.

3. Repair or Replace Components

Replace any faulty wheel speed sensors identified during inspection.
If the ABS module is defective, replace it with a compatible unit, ensuring proper coding if necessary.
Refill the brake fluid and bleed the brake system if fluid was replaced.
