Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors with a clean cloth.
Use a multimeter to test the sensors for continuity. If faulty, replace with new sensors.
Reconnect the wheel speed sensors after cleaning or replacement.

3. Check and Replace Brake Fluid

Remove the brake fluid reservoir cap and inspect the fluid level.
If low or contaminated, use a turkey baster to remove old fluid.
Refill with the correct type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the reservoir cap securely.

4. Test and Replace Brake Pedal Position Sensor

Access the brake pedal position sensor located near the brake pedal assembly.
Disconnect the electrical connector and check the sensor with a multimeter.
If the readings are out of range, replace the brake pedal position sensor.
Reconnect the sensor and ensure it is securely mounted.

5. Verify ABS Module Functionality

Inspect the ABS module for any visible damage or loose connections.
If necessary, perform a system reset using the OBD-II scanner to clear any fault codes.
Test drive the vehicle to ensure the traction control system operates correctly.
