Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the battery to prevent any electrical shorts.

2. Check ABS Wheel Speed Sensors

Locate each wheel speed sensor (typically found near the brake rotor).
Remove the wheel if necessary for better access.
Inspect the wiring and connectors for damage.
Clean the sensor and mounting area to remove any debris.
Reconnect any loose connectors securely.

3. Inspect the ABS Control Module

Locate the ABS control module, usually near the master cylinder or under the hood.
Check for any visible corrosion or loose wiring connections.
If corrosion is present, clean the terminals with electronic cleaner and a soft brush.
Reconnect any damaged wiring and ensure all connections are secure.

4. Replace Faulty Components

If any error codes indicate a specific sensor failure, replace the faulty ABS wheel speed sensor.
If the ABS control module is malfunctioning, it may need to be replaced or reprogrammed.
Ensure any replaced components match OEM specifications.

5. Reassemble and Test

Reconnect the battery.
Reinstall any components removed during inspection or repair.
Clear the error codes using the OBD-II scanner.
Test drive the vehicle to ensure the ABS light is off and the system is functioning properly.
