Solution

1. Preparation

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

2. Replace Faulty ABS Wheel Speed Sensor

Tools Required: Socket set, torque wrench, multimeter
Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the electrical connector from the faulty sensor.
Remove the sensor using a socket set; note the torque specifications for reinstallation.
Install the new sensor and reconnect the electrical connector.
Torque the sensor to manufacturer specifications.

3. Check and Replace ABS Fuse

Tools Required: Multimeter, fuse puller
Locate the ABS fuse in the fuse box; consult the owner’s manual for the exact location.
Use a multimeter to check for continuity in the fuse.
If the fuse is blown, replace it with a new one of the same amperage.

4. Refill Brake Fluid (if necessary)

Tools Required: Brake fluid, funnel
Check the brake fluid reservoir; if low, add the appropriate type of brake fluid as specified in the owner’s manual.
Ensure there are no leaks after refilling.

5. Reconnect Battery and Perform System Reset

Reconnect the negative battery terminal.
Start the vehicle and use the OBD-II scanner to clear any stored ABS fault codes.
Test drive the vehicle to ensure the ABS light is no longer illuminated.
