Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake fluid, cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Use a multimeter to check for continuity in the fuse; replace it if faulty.

3. Inspect Brake Fluid

Open the master cylinder reservoir cap.
Check the brake fluid level; top up with the manufacturer-recommended brake fluid if low.
Inspect the fluid for contamination; if dirty, a brake fluid flush may be necessary.

4. Clean and Inspect Wheel Speed Sensors

Jack up the vehicle safely and remove the wheels as needed for access.
Locate the ABS wheel speed sensors at each wheel hub.
Clean the sensors and their mounting surfaces with brake cleaner.
Reconnect any disconnected sensors and check for physical damage.

5. Test ABS Module

Reconnect the battery and use an OBD-II scanner to clear any existing codes.
Start the vehicle and check if the ABS light returns.
If the light returns, use a multimeter to test the voltage at the ABS module; replace the module if it does not meet specifications.
