This TSB involves 2006-2007 Chrysler PT Cruiser, 2006-2007 Dodge Ram truck and 2007 Dodge Caliber models. The notice relates to intermittent operation of electrical components due to the IOD (Ignition Off Draw) fuse not being fully seated.
The IOD fuse is used to prevent battery discharge during vehicle shipping and long term storage. The IOD fuse is located in the TIPM (Total Integrated Power Module). If the fuse is not completely inserted, partial contact of the fuse terminals could occur. Note: If the vehicle is to be stored for a long period of time, the IOD fuse should be release/removed.
Check to make sure that the IOD fuse is fully seated. When depressed into the carrier, an initial detent will be felt to overcome the “pre-hold” position. You must then continue to push straight down on the IOD pre-holder until no further downward movement is encountered. Note: If the fuse is not pushed down symmetrically (if pushed down crooked), two detents may be felt as each side snaps past the pre-hold position. Be sure to push to seat both sides fully.
