The engine runs unloaded while in the under-hood maintenance mode - you generate nothing.Uh... Time for a test. When you have the ign on, and pop the hood, the generator runs.
Will it charge while the ign is on in park?
If so, it is possible the charge rate could be higher.
It would be a neat experiment.
3. Circulate the oil after an oil change.The engine runs unloaded while in the under-hood maintenance mode - you generate nothing.
This mode exists solely for the benefit of the technician, not the vehicle's operation.
1. safety - know the vehicle is on and not be sticking your fingers into moving parts that could suddenly start up if you didn't know it was on
2. force the engine to turn to test various functions instead of having to wait for buffer level to reach a certain endpoint and have the engine kick on via normal programming
Ask his friend why he believes that to be the case.My husband has a friend with a 2012 Volt who says that if you pop the hood, the Volt will charge faster. This would be in a garage. Not sure if garage is heated, or whether it's charging on 110 or a Level 2. BS or ?????
