Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to avoid electrical shorts while working.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect ABS Fuse

Locate the fuse box and find the ABS fuse.
Use a multimeter to check for continuity in the fuse. If it is blown, replace it with a fuse of the same amperage.
Reconnect the battery and check if the ABS light is still illuminated.

3. Check Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate each wheel speed sensor on the brake assembly.
Inspect the sensor for physical damage or disconnection.
Use a multimeter to measure the resistance of the sensors; it should fall within the manufacturer's specifications.
Clean the sensors and connectors if dirt or debris is present.

4. Inspect ABS Module Connections

Locate the ABS module, usually found near the brake master cylinder.
Check all electrical connectors to ensure they are securely attached and free from corrosion.
If necessary, clean connectors with electrical contact cleaner and reconnect.

5. Test ABS Module

Reconnect the battery and use the OBD-II scanner to clear any error codes.
Take the vehicle for a test drive to see if the ABS light reappears.
If the light returns, further diagnostic testing of the ABS module may be required, which may involve specialized equipment.
