Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid, wire brush.
Gather all necessary tools and ensure the vehicle is parked on a level surface with the ignition turned off.

2. Inspect ABS Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the ABS fuse.
Use a multimeter or continuity tester to check if the fuse is blown.
Replace the fuse if defective, ensuring to use the same amperage as specified in the owner's manual.

3. Check Brake Fluid

Open the hood and locate the master cylinder reservoir.
Inspect the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the appropriate type of brake fluid as specified (typically DOT 3 or DOT 4).
If the fluid is dark or contaminated, consider a brake fluid flush.

4. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors on each wheel hub.
Visually inspect the sensors and wiring for any signs of damage or disconnection.
Clean any debris or corrosion from the sensor area using a wire brush.

5. Test ABS Module

Reconnect the OBD-II scanner to the vehicle and check for any stored ABS codes.
If codes are present, note them for further analysis.
If no codes are found and the light remains on, use a multimeter to check the voltage and ground at the ABS module connector.
Repair any wiring issues or replace the ABS module if necessary.
