Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensors using a clean cloth.
Check wiring for frays or disconnections.
Reconnect any loose wires and ensure proper placement of the sensors.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, add the manufacturer-recommended brake fluid type.
Look for leaks around brake lines and the master cylinder.
If leaks are found, repair or replace the affected components.

4. Test Traction Control Module

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use a multimeter to test the voltage at the traction control module connector.
Refer to the vehicle service manual for specific voltage requirements.
If the voltage is outside the specified range, replace the traction control module.

5. Check Tire Condition

Inspect all tires for proper inflation; refer to the manufacturer's recommended PSI.
Measure tread depth using a tread depth gauge; replace tires with insufficient tread.
Rotate tires if uneven wear is detected.
