Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter, brake cleaner.
Sub-steps:
1. Locate the wheel speed sensors (usually near the wheel hub).
2. Remove any debris or dirt using brake cleaner.
3. Use a multimeter to test the sensor's resistance; it should fall within the manufacturer's specifications.
4. If the sensor is faulty, disconnect the wiring harness and replace the sensor.

3. Check ABS System

Tools Required: OBD-II scanner.
Sub-steps:
1. Use the OBD-II scanner to check for ABS codes.
2. Clear any stored codes and see if they return after a test drive.
3. Inspect the ABS module for any visible leaks or damage.
4. If necessary, replace the ABS module or repair wiring as indicated by the diagnostic codes.

4. Verify Traction Control Switch

Tools Required: Multimeter, small screwdriver.
Sub-steps:
1. Locate the traction control switch in the vehicle.
2. Use a multimeter to test for continuity across the switch terminals.
3. If the switch is faulty, remove it and replace with a new unit.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the traction control light is still illuminated.
Take the vehicle for a test drive to ensure the system is functioning correctly.
