Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid (if needed).
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor connectors and visually inspect for damage or corrosion.
Use a multimeter to check the resistance of each sensor; it should typically be within 1,000 to 2,000 ohms.
Clean the sensor connectors and wiring harness if necessary.

3. Check ABS Module

Check for any fault codes related to the ABS module using the OBD-II scanner.
If faults are found, follow manufacturer-specific procedures to reset or replace the ABS module.
Ensure all wiring and connectors associated with the ABS module are intact and free from corrosion.

4. Inspect Brake Fluid Level

Remove the brake fluid reservoir cap and check the fluid level.
If low, top off with the manufacturer-approved brake fluid type (DOT 3 or DOT 4).
Inspect for leaks in the brake lines or at the calipers.

5. Test Traction Control Switch

Locate the traction control switch, typically found near the gear shifter.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if it fails to operate correctly.

6. Reconnect Battery and Clear Codes

Reconnect the vehicle’s battery.
Use the OBD-II scanner to clear any stored trouble codes.
Test drive the vehicle to ensure the traction control light does not reappear.
