Solution

1. Preparation

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

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Brake cleaner

2. Inspect and Replace ABS Sensors

Locate the wheel speed sensors on each wheel assembly.
Remove the sensor mounting bolts using the socket set.
Disconnect the wiring harness from the sensor.
Clean the mounting surface and inspect the sensor for damage.
If damaged, install a new ABS wheel speed sensor by reversing the removal steps.
Torque the sensor bolts to the manufacturer's specifications (typically around 7-15 ft-lbs).

3. Check and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the ABS fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with a fuse of the same amperage.
Reinstall the fuse and securely close the fuse box.

4. Inspect and Repair Wiring

Visually inspect the wiring connected to the ABS module and wheel speed sensors.
Use a multimeter to check for continuity in the wiring.
Repair any damaged wires using electrical tape or replace as necessary.
Reconnect any loose connectors securely.

5. Reset ABS Light

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any error codes from the ABS system.
Start the vehicle and verify that the ABS light is no longer illuminated.
