Solution

1. Preparation

Gather necessary tools and ensure the vehicle is in a safe working environment.
Tools required:
- Socket set
- Torque wrench

2. Disconnect Battery

Using a socket wrench, loosen the nut on the negative battery terminal.
Remove the negative terminal and tuck it away to prevent accidental contact.
Safety Warning: Ensure the vehicle is off and in park before disconnecting the battery.

3. Wait Period

Leave the battery disconnected for at least 10 minutes to ensure complete system reset.

4. Reconnect Battery

Reattach the negative battery terminal, ensuring it is snug and securely fastened.
Use a torque wrench to apply the manufacturer’s specified torque if necessary.

5. Idle Relearn

Start the engine and let it idle for about 5 minutes without any load.
This allows the engine control unit to relearn idle parameters.

6. Test Drive

Drive the vehicle smoothly, varying speeds and throttle inputs (light acceleration, hard acceleration, and deceleration).
This will help the transmission control unit adapt to the new driving conditions.
