Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire to access the wheel speed sensor.
Disconnect the sensor harness and inspect the connector for corrosion or damage.
Use a multimeter to test the sensor's resistance. Replace if out of specification.
Reinstall the wheel and tire.

3. Check Steering Angle Sensor

Tools Required: OBD-II scanner
Reconnect the battery and turn the ignition to the ON position without starting the engine.
Use the OBD-II scanner to check the steering angle sensor readings.
If necessary, recalibrate the sensor according to the manufacturer's specifications using the scanner.

4. Examine ABS Module

Tools Required: Torque wrench
Locate the ABS module and inspect its wiring harness for damage or corrosion.
If error codes indicate a failure, remove and replace the ABS module.
- Disconnect the battery.
- Unbolt the ABS module and disconnect the hydraulic lines cautiously.
- Install the new ABS module and torque the bolts to the manufacturer's specifications.
- Reconnect the battery.

5. Tire Check

Tools Required: Tire pressure gauge
Inspect tires for wear or damage.
Check tire pressures and adjust to manufacturer's recommendations.
Replace any worn or damaged tires.
