Battery Ignition Off Draw (IOD)

CIRCUIT OPERATION
A completely normal vehicle will have a small amount of current drain on the battery with the key out of the ignition. It can range from 5 to 25 milliamperes after all the modules time out. If a vehicle will not be operated for approximately a 20 days, the Ignition Off Draw (IOD) fuse should be pulled to eliminate the vehicle electrical drain on the battery. The IOD fuse is located in the Power Distribution Center (PDC). Refer to the PDC cover for proper fuse.
