0803600 - CIRCUITS AFFECTED BY IGNITION OFF DRAW FUSE
Date: 11/17/00
Model year(s): 2001
Description: The components/features that are disabled by the Ignition Off Draw (IOD) fuse varies from vehicle model to vehicle model. Below is a listing of what components/features are affected when the IOD fuse is removed in the WJ.
Details: (Labeled JB Power) Audio Amp, BCM Memory - BCM controlled components/features operate normally when the ignition switch is in the RUN position Flipper Window Power Release, Glovebox Lamp, HEVAC module (ATC), Instrument Panel Courtesy Lamps, Key Chime, Overhead Lamps, Power Outlets (front and rear) Radio, Rear Wiper, SKIM Module - Sentry Key equipped vehicles may require a longer crank time to start engine, Underhood Lamp, and Vehicle Theft Alarm (VTA) Set Lamp (VTA is disabled with IOD pulled).
The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from the battery with the ignition switch in the Off position. A normal vehicle electrical system will draw from five to thirty-five milliamperes (0.005 to 0.035 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper working order. Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control Module (PCM), digital clock, electronically tuned radio, and other modules which may vary with the vehicle equipment. A vehicle that has not been operated for approximately twenty days, may discharge the battery to an inadequate level. When a vehicle will not be used for twenty days or more (stored), remove the IOD fuse from the Power Distribution Center (PDC). This will reduce battery discharging.
