Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve and Address Error Codes

Reconnect the OBD-II scanner and note any error codes related to the ABS.
Clear the codes and check if they reappear after a test drive. If codes persist, proceed to the next steps.

3. Inspect and Replace ABS Components

Inspect ABS Wheel Speed Sensors:
- Locate the wheel speed sensors at each wheel assembly.
- Remove any debris or dirt from the sensor and connector.
- If damaged, replace with new sensors.
Check ABS Module:
- Remove the ABS module from the vehicle.
- Inspect for corrosion or physical damage to the module and its connectors.
- Replace if necessary.

4. Brake Fluid and System Check

Refill the brake fluid reservoir if low, using the manufacturer-recommended fluid type.
Inspect brake lines for leaks and replace any damaged sections.
Bleed the brake system to remove any air pockets.

5. Reassemble and Test

Reconnect all connectors and components.
Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light is still illuminated.
Perform a test drive to ensure the ABS system operates correctly.
