1. Preparation

Gather necessary tools.
Ensure all electrical components are turned off.
Tools required: OBD-II scanner, socket set.

Locate the negative terminal of the battery, usually marked with a "-" symbol.
Use a socket wrench to loosen the bolt on the negative terminal.
Carefully remove the terminal from the battery post and secure it away from any contact.

Allow the vehicle to remain disconnected for at least 15 minutes. This will ensure that all adaptations and learned values are cleared.

4. Reconnect Battery

Place the negative terminal back onto the battery post.
Tighten the bolt with a socket wrench until secure but avoid over-tightening.

5. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner prompts to clear any existing codes and reset adaptations as necessary.

6. Test Drive

Start the engine and let it idle for a few minutes.
Drive the vehicle under various conditions to allow the engine and transmission to relearn their adaptations.
