Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Screwdriver set

2. Address Fault Codes

Connect the OBD-II scanner and retrieve the ABS fault codes.
Note down the specific codes for reference.

3. Inspect and Clean ABS Sensors

Raise the vehicle and securely support it with jack stands.
Remove the wheel to access the ABS sensor.
Disconnect the sensor wiring harness.
Clean the sensor and the area around it with brake cleaner.
Reconnect the sensor and wheel, then lower the vehicle.

4. Check and Replace Faulty Components

If the OBD-II scan indicated a faulty sensor, remove the old sensor using a socket set.
Install the new ABS sensor and torque it to the manufacturer’s specifications (typically around 7-10 ft-lbs).
Repeat for all wheels if multiple sensors are faulty.

5. Inspect ABS Module and Wiring

Locate the ABS module (usually near the master cylinder).
Check for any loose or damaged wiring connections.
Inspect for signs of corrosion or damage on the module.
If faulty, replace the ABS module with a new one and follow installation procedures.

6. Final Assembly

Reconnect the battery and ensure all tools are removed from the undercarriage.
Perform a brake fluid check and top up if necessary.
Test the brakes to ensure proper function.
