Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse/Relay

Locate the fuse box (refer to the owner's manual for location).
Remove the ABS fuse and inspect for continuity using a multimeter.
- If blown, replace it with a new fuse of the same amperage.
Check the relay for proper function using a multimeter; replace if necessary.

3. Check and Clean Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors near each wheel hub.
Disconnect the sensor connector and inspect for corrosion or damage.
Clean the sensor and mounting area with brake cleaner.
Reconnect the sensor and ensure all wiring is intact.

4. Examine ABS Module and Wiring

Inspect ABS module connections for corrosion or damage.
Use a multimeter to check for proper voltage at the ABS module connectors.
Repair or replace any damaged wiring as necessary.

5. Brake Fluid Level Check

Check the brake fluid reservoir for proper levels.
Top off with manufacturer-recommended brake fluid if low.
Inspect for any visible leaks in brake lines or around the brake calipers.
