Solution

1. Preparation

Tools Required: OBD-II scanner, brake fluid, multimeter (if needed), basic hand tools (sockets, wrenches).
Ensure the vehicle is parked on a level surface, and the ignition is turned off before starting.

2. Clear ABS Codes

Connect the OBD-II Scanner:
- Plug the scanner into the OBD-II port, typically located under the dashboard near the driver's seat.
Turn on the Ignition:
- Turn the ignition key to the "ON" position without starting the engine.
Access ABS Module:
- Navigate through the scanner menu to access the ABS module and retrieve any trouble codes.
Clear Fault Codes:
- Follow the scanner prompts to clear the ABS fault codes. This process may vary by scanner model, but it generally involves selecting an option like "Erase Codes."

3. Test the ABS System

Start the Engine:
- Start the vehicle and allow it to idle.
Perform a Brake Test:
- Drive the vehicle at a slow speed (under 5 mph) and apply the brakes firmly to ensure the ABS system activates. You should feel a pulsing sensation in the brake pedal.
Check the ABS Light:
- Monitor the ABS light on the dashboard. If it remains off after the test, the reset was successful.
