- Close power windows in front doors to their top positions using electrical switches.
- Operate all power window switches again for at least one second in "close" direction to activate automatic one-touch function.
- Set clock to correct time.

- Check DTC memory:

Note:
DTCs will be stored in the memory because connectors have been disconnected. Therefore, check and erase DTC memory after installing the engine.
