Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather necessary tools and parts before starting the repair.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the cap and check the fluid level; top off with manufacturer-recommended brake fluid if low.
Inspect for any signs of leaks around the master cylinder.

3. Inspect ABS Fuses

Locate the fuse box (typically under the dashboard or engine compartment).
Use a fuse puller or pliers to check the ABS fuses.
Replace any blown fuses with the correct amperage rating.

4. Examine ABS Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Check for any signs of physical damage, corrosion, or loose connections.
Clean the sensors with electrical contact cleaner if necessary.

5. Test ABS Pump and Module

Connect a multimeter to the ABS pump's power supply terminals.
Check for proper voltage when the ignition is turned on.
If the pump does not activate, replace the ABS control module as needed.

6. Clear Codes and Test Drive

Use the OBD-II scanner to clear any stored ABS trouble codes.
Perform a test drive to ensure the ABS system is functioning correctly and the light is off.
