Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Gather necessary tools and safety equipment.
Disconnect the vehicle’s battery to prevent any electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench.
Remove the wheel corresponding to the ABS sensor that is faulty (as indicated by the error codes).
Disconnect the ABS sensor plug and carefully remove the sensor from its mounting location.
Clean the mounting area to remove dirt and debris.
Use a multimeter to test the sensor for proper resistance; replace if out of specifications.
Install the new ABS sensor, ensuring it is seated properly and torque to manufacturer specifications.
Reconnect the sensor plug securely.

3. Repair or Replace Damaged Wiring

Inspect the wiring harness leading to the ABS sensor for any signs of wear or damage.
If damaged, use electrical tape or heat shrink tubing to repair minor damage.
For severe damage, cut out the affected section and splice in new wiring, ensuring all connections are secure and insulated.

4. Check and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram on the cover.
Remove the fuse and check for continuity using a multimeter.
Replace with a new fuse of the same amperage if blown, ensuring a snug fit.

5. Reconnect Battery and Reset ABS Light

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored ABS error codes and reset the ABS light.
Start the vehicle and check if the ABS light remains off.
