Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the electrical connector from the wheel speed sensor.
4. Remove the sensor from its mounting location.
5. Install the new sensor by reversing the removal process.
6. Connect the electrical connector securely.

3. Check and Replace ABS Fuse and Relay

Sub-steps:
1. Locate the fuse box and identify the ABS fuse using the diagram on the cover.
2. Remove the ABS fuse and inspect it for continuity.
3. If blown, replace it with a fuse of the same rating.
4. Locate the ABS relay and test it for proper operation.
5. Replace the relay if it is not functioning correctly.

4. Inspect and Repair ABS Module

Sub-steps:
1. Locate the ABS module, which is typically under the hood or near the brake master cylinder.
2. Check for any visible signs of damage or leaks.
3. Disconnect the electrical connector and inspect for corrosion.
4. Tighten any loose connections and ensure the module is secure.
5. If the module is faulty, replace it with a new unit.
