Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any fault codes related to the ABS system.

3. Inspect ABS Components

ABS Fuse Inspection:
- Locate the fuse box according to the owner’s manual.
- Remove the ABS fuse and visually inspect it. Replace if blown.
Wiring and Connector Check:
- Follow the wiring harness from the ABS control module to the wheel speed sensors.
- Look for frayed wires, loose connections, or signs of corrosion.

4. Wheel Speed Sensor Testing

Resistance Measurement:
- Disconnect the electrical connector from each wheel speed sensor.
- Use a multimeter to measure resistance; it should typically fall within the manufacturer's specifications (check service manual).
- Replace any sensor that shows open or short circuit conditions.

5. ABS Control Module Inspection

Inspect the ABS control module for any signs of physical damage or corrosion.
If necessary, remove and replace the module following vehicle manufacturer specifications.
