Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, level location.
Tools Required:
- Wrench set (for battery terminal)
- OBD-II scanner (for checking error codes)

2. Disconnect the Battery

Use a wrench to loosen the nut on the negative battery terminal.
Carefully remove the negative terminal from the battery post.
Ensure the terminal does not contact the battery during the reset.

3. Wait for System Reset

Allow the system to remain disconnected for at least 10 minutes. This duration allows residual power to drain, effectively resetting the TCM.

4. Reconnect the Battery

Reattach the negative battery terminal to the battery post.
Tighten the nut securely with the wrench to ensure a good connection.

5. Check for Error Codes

Use an OBD-II scanner to read any error codes present in the system.
If codes are found, address them accordingly before concluding the reset.
