Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Scan and Clear Codes

Use an OBD-II scanner to scan for ABS-related trouble codes.
Take note of any codes present and clear them to see if the ABS light returns.

3. Inspect ABS Fuse

Locate the fuse box (refer to owner's manual for location).
Remove the ABS fuse and inspect for continuity using a multimeter.
- If the fuse is blown, replace it with one of the same amperage.

4. Check Wheel Speed Sensors

Remove the wheels to access the wheel speed sensors.
Disconnect the sensor connectors and test the sensors with a multimeter:
- Measure resistance; it should be within manufacturer specifications.
If a sensor is faulty, replace it with a new one.

5. Inspect and Test Brake Fluid

Check the brake fluid reservoir for proper fluid level.
If low, top off with the correct type of brake fluid (consult owner’s manual).
If the fluid is contaminated, perform a brake fluid flush.

6. Check Brake Pedal Switch

Locate the brake pedal switch and inspect its operation.
Test for continuity when the brake pedal is depressed.
If faulty, replace the brake pedal switch.
