Ignition-off draw fuse
Ignition-off draw fuse
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is removed when the vehicle is shipped from the factory. This fuse feeds various accessories that require battery current when the ignition switch is in the Off position, including the clock and radio station preset memory functions. The fuse is removed to prevent battery discharge during vehicle storage.
When removing or installing the IOD fuse, it is important that the ignition switch be in the Off position.
Failure to place the ignition switch in the Off position can cause the radio display to become scrambled when the IOD fuse is removed and replaced.
Removing and replacing the IOD fuse again, with the ignition switch in the Off position, will correct the scrambled display condition.
The IOD fuse should be checked if the radio is inoperative. The IOD fuse is located in the Power Distribution Center (PDC). Refer to the PDC label for IOD fuse identification and location.
