Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to prevent any electrical short circuits.

2. Inspect and Replace Wheel Speed Sensors

Step 1: Raise the vehicle using a jack and secure it on jack stands.
Step 2: Remove the wheel on the affected side to access the wheel speed sensor.
Step 3: Disconnect the electrical connector from the wheel speed sensor.
Step 4: Remove the sensor from its mounting location using a socket set.
Step 5: Install the new wheel speed sensor and reconnect the electrical connector.
Step 6: Reinstall the wheel and lower the vehicle.

3. Check and Repair Brake System

Step 1: Open the hood and locate the brake fluid reservoir.
Step 2: Check the brake fluid level; refill if low using the manufacturer's recommended fluid.
Step 3: Inspect brake lines and hoses for leaks or damage, and repair or replace as necessary.

4. Inspect and Repair ABS Module

Step 1: Locate the ABS module, typically found near the brake master cylinder.
Step 2: Inspect wiring and connections for corrosion or damage; repair or replace if needed.
Step 3: If the ABS module is suspected to be faulty, follow the manufacturer's instructions for removal and replacement.

5. Check Steering Angle Sensor

Step 1: Use a diagnostic tool to access the steering angle sensor data.
Step 2: Compare the readings to the specified range in the service manual; if out of range, proceed with recalibration or replacement.
Step 3: Recalibrate the sensor using the diagnostic tool as per the manufacturer’s instructions.
