Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, wire brush, dielectric grease.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor from its mounting bracket using a socket set.
Clean the sensor tip with a wire brush to remove any dirt or debris.
Check the sensor wiring for any signs of wear or damage.
Reinstall the sensor and ensure it is securely fastened.

3. Check ABS Module Connections

Locate the ABS module, typically found near the master cylinder.
Inspect the wiring harness connected to the ABS module for loose connections or corrosion.
Use a multimeter to test for proper voltage at the ABS module connector.
If any issues are found, repair or replace the damaged wiring.
Reconnect the wiring harness securely to the ABS module.

4. Replace ABS Module (if necessary)

If the ABS module is determined to be faulty, remove it by unbolting it from its mounting bracket using a socket set.
Disconnect all electrical connectors from the ABS module.
Install the new ABS module by securing it in place and reconnecting all electrical connectors.
Torque the mounting bolts to the manufacturer's specifications (refer to service manual for exact values).

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Clear any stored error codes using the OBD-II scanner.
Start the vehicle and perform a test drive to ensure the ABS warning light is off and the system is functioning correctly.
