Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect Wheel Speed Sensors

Tools Required: Multimeter, socket set
Sub-steps:
1. Locate the wheel speed sensors on each wheel hub.
2. Disconnect the electrical connector from each sensor.
3. Use a multimeter to check the resistance of each sensor (should be within manufacturer specifications).
4. Inspect wiring and connectors for signs of wear or damage.
5. Clean sensors with appropriate cleaner if dirt or debris is present.

Tools Required: OBD-II scanner
Sub-steps:
1. Reconnect the battery and turn the ignition on without starting the engine.
2. Use the OBD-II scanner to check for any stored ABS or traction control fault codes.
3. If codes are present, diagnose based on the specific error codes received.
4. Clear codes and test drive the vehicle to see if the light reappears.

4. Inspect Traction Control Switch

Tools Required: Screwdriver
Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Remove the switch from the dash panel.
3. Check for any sticking or mechanical failure.
4. Test the switch for continuity using a multimeter.
5. Replace if faulty.

5. Final Checks

Tools Required: Tire pressure gauge
Sub-steps:
1. Check tire pressures to ensure they are at the recommended levels.
2. Inspect all tires for uneven wear or damage.
3. Ensure all tires are of the same type and size.
