Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensors using a clean cloth.
Check the sensor wiring for fraying or disconnection, and repair as necessary.

3. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the brake fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4).
Inspect for any visible leaks around the brake lines and connections.

4. Examine ABS Module Wiring

Locate the ABS module, usually near the brake master cylinder.
Inspect the wiring harness for any signs of wear, corrosion, or loose connections.
Reconnect any loose wires and repair damaged wiring using electrical tape or heat-shrink tubing.

5. Test and Replace Faulty Sensors

If error codes indicate a specific faulty sensor (e.g., wheel speed sensor or throttle position sensor), remove the component:
- Disconnect the electrical connector.
- Remove the mounting bolts.
- Install the new sensor by reversing the removal steps, ensuring proper torque specifications are followed (typically around 10-15 Nm).
