Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from each sensor.
Remove the sensor using the appropriate socket or wrench.
Inspect the sensor for dirt or damage; clean or replace as needed.
Reinstall the new or cleaned sensor, ensuring proper seating and torque specifications (typically 7-10 Nm).

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, add the manufacturer's recommended brake fluid (usually DOT 4).
Ensure there are no leaks in the brake system.

4. Test ABS Module

Reconnect the battery and use the OBD-II scanner to check ABS module status.
If codes are present, follow the manufacturer's diagnostic procedures for the ABS system.
Repair or replace any faulty components as indicated by the diagnostic codes.

5. Inspect Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch for continuity when pressed.
If faulty, replace the switch with a new part.
