Control Description

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

Power ON

VCM monitors the 12V battery voltage during POWER ON cycle and immediately starts charging when VCM judges that the voltage is lowered.

When Vehicle is Left for a Long Period of Time

VCM measures the time of no operation using its internal timer. If the time of no operation reaches 120 hours, VCM performs automatic charge for 5 minutes.

VCM resets the no operation status continuous time when the vehicle satisfies one of the following conditions.

NOTE:
  • During automatic 12V battery charging, the charging status indicator blinks.
  • The automatic 12V battery charge control does not start within approximately one hour when the power switch is turned ON/OFF.
