Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Repair Wiring

Sub-steps:
- Visually inspect the wiring harness connecting to the ABS module for frays or corrosion.
- Clean any corroded connectors using electrical contact cleaner.
- Repair any damaged wires using solder and heat-shrink tubing.

3. Replace Faulty Wheel Speed Sensors

Tools Required: Socket set, multimeter
Sub-steps:
- Remove the wheel and tire assembly to access the wheel speed sensor.
- Disconnect the sensor connector.
- Remove the mounting bolts and take out the wheel speed sensor.
- Install the new sensor by reversing the removal steps and ensuring it is secured properly.

4. Replace ABS Module (if necessary)

Tools Required: Socket set, torque wrench
Sub-steps:
- Locate the ABS module, typically found near the brake master cylinder.
- Disconnect the electrical connectors and brake lines from the ABS module.
- Remove the mounting bolts and take out the defective ABS module.
- Install the new ABS module by securing it with the bolts to the specified torque (usually around 10-12 ft-lbs).
- Reconnect the brake lines, ensuring they are tight and leak-free.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and allow it to enter a self-test mode for the ABS.
Verify that the ABS warning light goes off after the self-test.
