Solution

1. Preparation

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

2. Address Faulty ABS Sensors

Remove the wheel and tire assembly to access the ABS sensor.
Unplug the ABS sensor connector.
Inspect the sensor for dirt or damage; clean with brake cleaner if necessary.
If the sensor is damaged, replace it with a new one.
Reconnect the ABS sensor and ensure the connector is secure.
Reinstall the wheel and tire assembly.

3. Check Brake Fluid Level

Locate the brake master cylinder reservoir.
Remove the cap and check the brake fluid level; it should be above the minimum mark.
If low, add the recommended type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Secure the cap back onto the reservoir.

4. Inspect ABS Control Module

Locate the ABS control module, usually found near the master cylinder.
Ensure all electrical connectors are firmly attached.
Look for signs of corrosion or damage; clean any corroded connections with an electrical contact cleaner.
If the module appears faulty, it may need replacement.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any ABS trouble codes.
Start the vehicle and observe if the ABS light remains off.
