Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, basic hand tools.
Ensure the vehicle is on a flat surface and securely supported if lifting is required.
Disconnect the battery to prevent electrical shorts.

2. Addressing Faulty Wheel Speed Sensors

Locate and remove the wheel speed sensors at each wheel hub.
- Tools: Socket set.
Clean the mounting area and the sensor itself with a suitable cleaner to remove any debris.
Inspect the wiring harness for frays or breaks. Repair or replace as necessary.
Reinstall the sensors and torque them to the manufacturer's specifications.

3. Replacing the ABS Module

If error codes indicate a faulty ABS module, locate the module (typically mounted near the master cylinder).
Disconnect the electrical connectors and brake lines (be prepared for brake fluid leakage).
- Tools: Wrench set.
Remove the mounting bolts and extract the module.
Install the new ABS module and torque bolts to the specified values.
Reconnect the brake lines and electrical connectors securely.

4. Final Steps

Reconnect the battery.
Clear any stored codes using the OBD-II scanner.
Test drive the vehicle to ensure the ABS system functions correctly and the light does not re-illuminate.
