Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. ABS Fuse Inspection

Locate the fuse box and identify the ABS fuse using the diagram on the cover.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown, replace with a fuse of the same amperage and secure it back in place.

3. Wheel Speed Sensor Inspection

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensors.
Disconnect the sensor connector and use a multimeter to check for resistance; it should be within manufacturer specifications.
- If faulty, replace the wheel speed sensor.

4. ABS Module Inspection

Locate the ABS module, typically near the brake master cylinder.
Inspect connectors and wiring for signs of corrosion or physical damage.
If necessary, clean connections with electrical contact cleaner and reconnect.

5. Brake Fluid Check

Open the brake fluid reservoir cap and check fluid level and condition.
If contaminated or low, flush the brake system and refill with the manufacturer-recommended brake fluid.

6. Reconnect Battery and Test

Reconnect the battery and ensure all components are secure.
Start the vehicle and check if the ABS light remains illuminated.
