Cutlass V6-191 3.1L VIN M SFI (1998)
Body Function Controller: Description and Operation
Battery Rundown Function
The Battery Rundown Function helps to prevent the Battery from deep discharge due to interior/courtesy lighting being inadvertently left ON. It
performs this function by turning OFF the inadvertent power output (which provides power for the interior/courtesy lighting).
When the Ignition Switch is turned to the OFF position a time out period is started. This time out period is 3 minutes when the odometer is less than 24
km (15 miles) and it is 20 minutes when the odometer is greater than 24 km (15 miles). When the time out expires the inadvertent power output is
turned off.
