Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shocks.
Gather tools and parts needed for the repair.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel.
Clean any dirt or debris from the sensors and connectors.
Use a multimeter to test the resistance of each sensor; it should typically be between 1,000 to 2,500 ohms.
Replace any faulty sensors.

3. Check Brake System

Inspect brake pads and rotors for wear; replace if necessary.
Check brake fluid levels and top off with the recommended fluid.
Inspect for any leaks in the brake lines or connections.

4. Test Traction Control Module

Reconnect the battery and start the vehicle.
Use the OBD-II scanner to access the traction control module.
Follow the scanner's instructions to perform any necessary tests or resets.

5. Verify ABS System

Inspect the ABS fuse and replace if blown.
Check wiring and connectors for any signs of corrosion or damage.
Clear any fault codes and test drive the vehicle to see if the issue persists.
