Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a soft cloth.
Disconnect the electrical connector and inspect for corrosion; clean if necessary.
Reconnect the connector and ensure it is secure.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the brake fluid level; if low, top it up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Check for any visible leaks in the brake lines or connections.

4. Inspect ABS Module and Wiring

Locate the ABS module, usually found near the master cylinder.
Check the wiring harness for any signs of wear, damage, or corrosion.
If any wires are damaged, repair or replace them as necessary.

5. Test Steering Angle Sensor

Use a scan tool to check if the steering angle sensor is functioning correctly.
If the sensor is faulty, it will need to be recalibrated or replaced according to the manufacturer’s specifications.
