Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter
Ensure the vehicle is parked on a level surface and the ignition is off before starting.
Disconnect the battery for safety (remove the negative terminal).

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Select the option to read and clear diagnostic trouble codes (DTCs) from the traction control system.
Confirm that the codes have been cleared successfully.

3. Reconnect Battery

Reconnect the negative terminal of the battery.
Ensure connections are tight and secure to prevent any electrical issues.

4. Test Traction Control System
