Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel on which the sensor is located using a socket set.
Locate the wheel speed sensor and unplug the connector.
Clean the sensor with brake cleaner and a soft cloth.
Check the wiring for any signs of wear or damage; repair or replace as necessary.
Reconnect the sensor and reinstall the wheel.

3. Check ABS Module and Wiring

Locate the ABS module under the hood or inside the vehicle, depending on the model configuration.
Inspect the module for any signs of corrosion or damage.
Use a multimeter to check the voltage at the module’s power supply and ground pins.
Repair any faulty wiring or connectors as needed.
Reconnect the module and ensure all connections are secure.

4. Verify Brake Fluid Condition

Locate the brake fluid reservoir and check the fluid level.
If low, top off with the recommended brake fluid type (DOT 4).
If the fluid appears contaminated (dark or has debris), perform a brake fluid flush.
Bleed the brakes to remove any air from the system.

5. Test Steering Angle Sensor

Reconnect the battery and turn on the ignition.
Use a diagnostic tool to access the steering angle sensor readings.
Compare the readings with the manufacturer specifications.
If out of range, recalibrate the sensor according to the service manual.
