Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
IOD Fuse: Description
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is mounted in an asymmetrical holder within the Integrated Power Module (IPM). Prior to delivery to the customer, this fuse is positioned to provide power for the "always on" equipment only when the ignition is in the ON position. This avoids long term drain on the battery during shipping and storage. Dealer personnel are to reverse the IOD fuse in its holder, switching these features to battery power just prior to new vehicle delivery.
