Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shorts during inspection.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire assembly from the affected wheel.
Locate the wheel speed sensor and disconnect the electrical connector.
Use a multimeter to test the resistance of the sensor. The resistance should be within the manufacturer's specified range.
If the sensor is faulty, replace it with a new unit.

3. Check ABS Module and Wiring

Tools Required: Socket set, wiring diagram
Locate the ABS module and inspect for any visible signs of damage or corrosion.
Check the wiring harness for frays, breaks, or loose connections.
If issues are found, repair or replace the wiring or module as needed.

4. Test Traction Control Switch

Tools Required: Multimeter
Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
If the switch is defective, replace it with a new switch.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal after all repairs are completed.
Use an OBD-II scanner to clear any error codes related to the traction control system.
