Battery Rundown Protection

Battery Rundown Protection helps prevent the battery from deep discharge when you have inadvertently left the interior/courtesy lighting on (rear compartment lid open, door ajar, map light on, etc.). Battery Rundown Protection performs this function by turning off the inadvertent power output. This provides a battery voltage for the interior/courtesy lighting.

Once the ignition switch is turned off, a 20 minute time-out period begins. When the time-out expires, the inadvertent output is turned off. While the inadvertent power output is off, the inadvertent feed back is monitored. If a high to low transition occurs, or if a hardware/software wake up occurs, the inadvertent output is turned back on and the timer is restarted.
