Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Scan and Clear Codes

Use an OBD-II scanner to read the ABS codes.
Record any codes for reference.
Clear the codes and take the vehicle for a test drive to see if the light returns.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor (typically mounted near the wheel hub).
Remove any debris or dirt around the sensor.
Disconnect the sensor connector and check for continuity with a multimeter.
Replace any faulty sensors with new ones, ensuring they are properly seated.

4. Check ABS Module and Wiring

Locate the ABS control module, usually found near the master cylinder.
Disconnect the module and inspect the connectors for corrosion or damage.
Use a multimeter to check for proper voltage at the module when the ignition is turned on.
Repair or replace any damaged wiring or connectors.

5. Reassemble and Test

Reconnect the battery terminal.
Ensure all components are securely reassembled.
Perform a test drive to confirm that the ABS light has turned off and the system is functioning properly.
