Solution

1. Preparation

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

2. Inspect and Replace Wheel Speed Sensors

Locate Wheel Speed Sensors:
- Identify the location of the wheel speed sensors at each wheel hub.
Remove Sensor:
- Use a socket set to remove the mounting bolts and carefully pull out the sensor from the hub.
Inspect Sensor:
- Check for physical damage or dirt buildup on the sensor and the connector.
Replace if Necessary:
- If damaged, install a new wheel speed sensor and secure it with the bolts to the recommended torque (typically 15-20 ft-lbs).

3. Check ABS Module and Wiring

Visual Inspection:
- Inspect the ABS module on the vehicle for any visible damage or corrosion.
Test Wiring Connections:
- Ensure all wiring connectors are secure and free from corrosion.
Repair or Replace:
- If issues are found, repair the wiring or replace the ABS module as necessary.

4. Brake Fluid Inspection

Check Fluid Level:
- Open the brake fluid reservoir and check if the fluid is at the recommended level.
Fluid Quality:
- Inspect the fluid for contamination or discoloration; if necessary, flush the brake system with new brake fluid (DOT 3 or DOT 4).
Refill:
- Refill with fresh brake fluid and securely close the reservoir cap.

5. Reconnect Battery and Reset ABS Light

Reconnect Battery:
- Reconnect the negative battery terminal and ensure it is tight.
Clear Codes:
- Use the OBD-II scanner to clear any stored ABS trouble codes.
Test Drive:
- Conduct a test drive to verify that the ABS light remains off and the braking system operates correctly.
