Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris surrounding the sensors and connector points.
If damaged, replace the sensors with new components.
Reconnect the sensors and ensure the connectors are secure.

3. Check and Replace Brake Fluid

Remove the reservoir cap and check the brake fluid level.
If low, add the recommended type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
If fluid is contaminated, perform a brake fluid flush.
- Use a brake bleeder kit to remove old fluid from the system.
- Refill with fresh brake fluid and bleed the brake lines until fresh fluid is seen at each caliper.

4. Inspect and Replace ABS Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Check the ABS fuse for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage rating.

5. Test and Replace ABS Module (if necessary)

If error codes indicate a faulty ABS module, it may need replacement.
Remove the module by disconnecting the wiring harness and unscrewing the mounting bolts.
Install the new module, reconnect the harness, and secure it in place.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminal.
Use the OBD-II scanner to clear any stored ABS trouble codes.
