Solution

1. Preparation

Gather tools and parts needed for the repair. Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, cleaning materials.

2. Retrieve and Address Diagnostic Codes

Use the OBD-II scanner to retrieve ABS trouble codes.
Write down the codes and refer to a repair manual for specific troubleshooting steps associated with each code.
Clear the codes and take the vehicle for a test drive to see if the ABS light returns.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands for safety.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor's electrical connector and inspect for corrosion.
Clean the sensor and surrounding area with brake cleaner or appropriate cleaning solution.
Reconnect the sensor and reinstall the wheel.

4. Check ABS Module and Wiring

Locate the ABS module, typically found near the brake master cylinder.
Inspect the module for any fluid leaks or physical damage.
Use a multimeter to check for proper voltage at the ABS module connector.
Inspect the wiring harness for frays or disconnections and repair as necessary.

5. Replace Faulty Components

If any wheel speed sensors or the ABS module are found to be faulty during inspection, replace them with OEM or high-quality aftermarket parts.
Follow manufacturer specifications for torque values during reinstallation.
