Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface and the ignition is turned off before beginning work.

2. Check ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the ABS fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with one of the same amperage.

3. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it on jack stands.
Access each wheel speed sensor located near the brake rotor.
Clean any dirt or debris from the sensor and the mounting area.
Check the wiring harness for cracks or disconnections. Repair or replace as necessary.

4. Examine Brake Fluid Levels

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid level is within the recommended range. If low, top up with the manufacturer's specified brake fluid.
Inspect the reservoir for any signs of leaks or cracks.

5. Test ABS Pump and Module

With the OBD-II scanner, perform a function test of the ABS pump to see if it activates.
Check for any fault codes related to the ABS module and address them accordingly.
If the ABS module is malfunctioning, it may need to be repaired or replaced.
