Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning supplies, basic hand tools.
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Check and Replace ABS Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove any blown ABS fuses.
Replace with fuses of the same amperage rating.

3. Inspect and Clean Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the ABS wheel speed sensors.
Clean the sensors with a soft cloth or brush to remove dirt and debris.
Reinstall the wheels and lower the vehicle.

4. Brake Fluid Inspection and Refill

Remove the cap of the brake fluid reservoir located near the master cylinder.
Check the fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4).
Reinstall the cap securely.

5. ABS Module and Pump Testing

Reconnect the battery terminal.
Use a multimeter to check the ABS module connections for proper voltage.
If the module is malfunctioning, replace it with a new unit following manufacturer specifications.
