Solution

1. Preparation

Gather all 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 electrical shock.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, flathead screwdriver
Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the sensor connector by gently prying open the locking tab with a flathead screwdriver.
Use a multimeter to test continuity; if the sensor is faulty, proceed with replacement.
Remove the mounting bolt securing the sensor and pull it out of the hub.
Install the new sensor by reversing the removal steps and securing it with the bolt.

3. Check and Replace ABS Fuse

Tools Required: Fuse puller, multimeter
Locate the fuse box (refer to the owner’s manual for location) and find the ABS fuse.
Use a fuse puller to remove the fuse and inspect it for damage.
Test the fuse with a multimeter for continuity; replace if faulty.
Reinsert the new fuse into the slot.

4. Brake Fluid Inspection

Tools Required: Brake fluid tester, clean rag
Check the brake fluid reservoir under the hood for proper fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for any visible leaks around brake lines and fittings.

5. Reconnect Battery and Clear Codes

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