Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning solvent.
Gather all necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes related to the traction control system.
Clear error codes and perform a test drive to see if the issue reoccurs.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure with jack stands.
Remove the wheel to access the wheel speed sensor.
Check for physical damage or debris around the sensor; clean if necessary.
Use a multimeter to check the sensor's resistance; replace if readings are outside the manufacturer's specifications.

4. Check Brake Fluid and System

Inspect the brake fluid reservoir; ensure it is at the correct level and top off with the recommended brake fluid if low.
Look for any signs of leaks in the brake lines or around the calipers.
If leaks are found, replace the damaged lines or components.

5. Examine ABS Module and Wiring

Locate the ABS module and inspect the wiring for any signs of wear, corrosion, or disconnection.
Clean any corroded connections using electrical cleaner.
Reconnect any loose wires and ensure a secure fit.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check the switch's functionality by measuring continuity when pressed.
Replace the switch if it does not function correctly.
