Solution

1. Preparation

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

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and document any error codes related to the traction control system.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Visually inspect wiring for frays, breaks, or disconnections.
Use a multimeter to test the resistance of each sensor (specification is typically 1000-2000 ohms).
Replace any faulty sensors.

4. Check Brake Fluid Level

Remove the cap from the brake fluid reservoir.
Inspect the fluid level; it should be within the marked range.
If low, top off with the manufacturer-recommended brake fluid.
Inspect for any visible leaks around brake lines and components.

5. Inspect ABS Control Module

Locate the ABS control module, usually near the master cylinder.
Check for any visible damage or corrosion on the connectors.
Use the OBD-II scanner to clear any stored codes and test drive the vehicle to see if the light returns.

6. Test Traction Control Switch

Locate the traction control switch/button on the dashboard.
Use a multimeter to test for continuity when the button is pressed.
If defective, replace the switch.
