Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel on the affected axle to access the wheel speed sensor.
Unplug the wheel speed sensor connector.
Use a multimeter to check the sensor’s resistance (should be within manufacturer specifications).
Clean the sensor and surrounding area if dirt or debris is present.
Reconnect and secure the sensor. Reinstall the wheel.

3. Check ABS Module

Tools Required: OBD-II scanner
Reconnect the battery.
Start the vehicle and use the OBD-II scanner to check for ABS-related fault codes.
If codes indicate a failure, inspect the ABS module wiring and connections for damage.
If necessary, replace the ABS module (follow manufacturer procedures for replacement).

4. Verify Traction Control Switch Functionality

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 faulty, replace it with a new one.

5. Clear Error Codes

Tools Required: OBD-II scanner
After repairs, connect the OBD-II scanner and clear any stored error codes.
Ensure that the traction control light is extinguished.
