Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Wheel Speed Sensors

Step 2.1: Raise the vehicle using a jack and secure it with jack stands.
Step 2.2: Remove the wheel corresponding to the faulty speed sensor (if identified from diagnostic).
Step 2.3: Disconnect the electrical connector of the wheel speed sensor.
Step 2.4: Remove the mounting bolt of the wheel speed sensor using a socket set.
Step 2.5: Install the new wheel speed sensor by reversing the removal steps and ensuring it is securely mounted.
Tools Required: Socket set, torque wrench, screwdriver.

3. Check and Replace ABS Fuse

Step 3.1: Locate the ABS fuse in the fuse box (refer to the owner's manual for the exact location).
Step 3.2: Pull out the fuse and visually inspect it for any signs of blowing.
Step 3.3: If blown, replace with a fuse of the same amperage.
Tools Required: Fuse puller or pliers.

4. Inspect and Repair ABS Module Wiring

Step 4.1: Locate the ABS module under the hood.
Step 4.2: Inspect the wiring harness for any fraying or damage.
Step 4.3: If damaged, repair the wiring using appropriate connectors and heat-shrink tubing.
Tools Required: Wire stripper/crimper, heat gun.

5. Reconnect Battery and Clear Codes

Step 5.1: Reconnect the battery terminals securely.
Step 5.2: Use the OBD-II scanner to clear any stored ABS fault codes.
Step 5.3: Start the vehicle and check if the ABS light remains off.
