Solution

1. Preparation

Gather tools and required parts.
Disconnect the vehicle battery to ensure safety.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Ratchet set, socket set, wire brush, and cleaning solvent.
Remove the wheel corresponding to the sensor in question.
Disconnect the electrical connector from the wheel speed sensor.
Clean the sensor and its mounting area with a wire brush and cleaning solvent to remove any debris or corrosion.
Reconnect the sensor and ensure it is securely mounted. Repeat for all wheel speed sensors if necessary.

3. Check Brake Fluid Level

Tools Required: None.
Locate the brake master cylinder reservoir under the hood.
Check the brake fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect for any visible leaks around the master cylinder and brake lines.

4. Inspect ABS Module Connections

Tools Required: Multimeter.
Locate the ABS module, typically near the brake master cylinder.
Check the electrical connectors for corrosion or loose connections.
Use a multimeter to test for proper voltage and continuity at the ABS module connections as per the service manual specifications.

5. Reset the Traction Control System

Tools Required: OBD-II scanner.
With the battery reconnected, use the OBD-II scanner to clear any fault codes.
Turn on the ignition without starting the engine and verify if the traction control light is still illuminated.
Start the engine and check the traction control light again.
