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 shorts.
Gather necessary tools and parts.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel corresponding to the sensor being inspected.
Clean the wheel speed sensor area with a brake cleaner to remove debris.
Check the sensor for physical damage; replace if necessary.
Reinstall the wheel and torque lug nuts to the manufacturer's specifications.

3. Check and Repair ABS Module Wiring

Locate the ABS module and inspect wiring for frays or corrosion.
Use a multimeter to test for continuity in the wiring.
Repair any damaged wires with appropriate connectors or electrical tape.

4. Test and Calibrate Steering Angle Sensor

Reconnect the battery and turn the ignition on without starting the engine.
Use a scan tool to access the steering angle sensor data.
If calibration is necessary, follow the manufacturer's procedure for recalibrating the sensor.

5. Replace Faulty Components

If any components such as the wheel speed sensors or steering angle sensor are found to be faulty, replace them with OEM parts.
Follow the specific installation instructions for each component and ensure proper torque specifications are met.
