Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Retrieve Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner prompts to retrieve and note any error codes related to traction control.

3. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Lift the vehicle and remove the wheel to access the wheel speed sensors.
Disconnect the connector from the sensor and use a multimeter to check for continuity.
If the sensor is faulty, replace it with a new one, ensuring proper alignment and connection.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the fluid level is within the recommended range; if low, top it off with the manufacturer-recommended brake fluid.
Inspect for any leaks in the braking system.

5. Inspect ABS Module

Tools Required: Socket set.
Locate the ABS module and visually inspect for any signs of damage or corrosion.
If necessary, clean the module connections and ensure all wiring is intact.

6. Replace Traction Control Switch (if necessary)

Tools Required: Socket set, flathead screwdriver.
Remove the trim panel surrounding the traction control switch.
Disconnect the switch connector and replace it with a new switch.
Reassemble the trim panel and ensure the switch operates correctly.
