Ignition-Off Describe (IOD) is a normal circumstance where ability drains from a auto'south battery while the ignition switch is off. Vehicles that have not operated for 20 days or more will experience heavy bombardment drainage. Earlier storing a vehicle, remove the IOD fuse to reduce discharge. Merely where is the IOD fuse located?

The Ignition-Off Draw (IOD) fuse is located in the Total Integrated Ability Module (TIPM), commonly found near the battery in the engine compartment. Depending on your vehicle model, it may elsewhere, such every bit below the steering wheel or dashboard.

This article provides a consummate guide on the IOD fuse, including its location in dissimilar vehicle types. Information technology also covers its functions, how to remove and supervene upon it, and tests y'all can perform.

What Is the IOD Fuse?

The IOD fuse is a device used to prevent battery discharge while the vehicle is not in use. It's beneficial when shipping or for long-term storage. The IOD fuse provides overcurrent protection of electrical circuits that goes through it. A protective clip encases the fuse, which a vehicle owner can pull up to break the circuit. Information technology is a sacrificial device equally information technology melts or gets burnt when likewise much current flows through it.

The IOD fuse may disconnect from the TIPM to reduce the normal drainage of a vehicle's battery depletion. Disconnection is nigh common during transportation and pre-commitment storage. Dealer personnel must reconnect the IOD fuse once the automobile is ready for delivery to restore its full electrical system operation. Information technology is important to note that disconnecting the IOD fuse will not eliminate IOD, but only reduce or slow it down. Should an owner disconnect the battery's negative cable to stop normal IOD, the battery should withal be tested and recharged at regular intervals to prevent it from condign damaged.

Where Is the IOD Fuse Located?

The IOD fuse location varies depending on the make and model of the vehicle. The listing below is not exhaustive but should give you lot a good thought of where to look for the IOD fuse depending on the car you ain:

Indications of a Bad IOD Fuse

When the IOD fuse blows, it usually produces problematic symptoms and alerts the driver of a potential issue.

Systems Afflicted by a Blown Fuse:

  • Interior dome/reading/map lights
  • Power locks
  • Open-and-close door module & window motors
  • Radio/CD/Cassette player (the unit may still show trim lighting)
  • The trip odometer memory (would reset each time the car is shut down)
  • Left/Right visor vanity and underhood lamps
  • DLC connector
  • Electric or retention seats
  • GPS equipment
  • Wireless control module or WCM
  • Clock
  • Remote key receiver
  • Remote engine starting time module
  • Heater fan on warm engine detect
  • CCN wake-up with ignition off & Homelink (for PT Cruiser models)
  • Security organisation & alert (security light stays on the dash despite your vehicle not turning over)

Blown IOD Fuse Symptoms:

  • Parasitic battery drain
  • No fuse fault message
  • Nuance cluster blinking wildly
  • Engine won't creepo
  • Radio, dome lights, and cargo lights quite working
  • Windows wouldn't go downwardly
  • Horn sounding when the doors are locked

These symptoms would unremarkably hint of a blown IOD fuse. Merely to be certain, do the following steps:

  1. Buy a fuse tester/puller at a local machine parts store to individually pull the fuses related to your motorcar functions. They include those in the fuse box by the driver's left knee joint inside the auto and a 40-amp fuse upwardly in the PDC under the hood. If all these bank check out okay, then information technology would be an indicator that your IOD fuse is the culprit.
  2. Disconnect the negative cablevision from the battery. Take one end of the multimeter, put it on the negative postal service, and so put the other on the negative cablevision terminal. And so pull the fuses 1 by i. Pulling the faulty fuse would give a reading of 0 amp or testify a sudden drop in amperage reading.
  3. Dominion out defective components by doing the following:
  • A load test and a diode test – to come across if both your battery and alternator are good.
  • Clean all of the grounds, including whatsoever of the electric connections and terminals.
  • Replace the positive and negative battery terminals with something slightly heavier duty.
  • Replace the Key Play a joke on batteries with a proficient quality proper noun brand.

Farther Tips:

Take annotation of known problematic cars similar Contrivance Grand Caravans and 1st generation Jeeps with the old wireless control module spike issue. For Jeeps, the battery bleed happens when the security system goes through a panic attack, or if the (WCM) metallic key bract gets static electricity buildup and fails to read the transponder. A 2008 TSB instructed Jeep owners to do an IOD fuse disconnect for 10 seconds. If this step failed, the technician was to replace the WCM. These vehicles may prove symptoms similar to a blown IOD fuse, so information technology is best to eliminate all other possible reasons earlier last that the IOD is the crusade.

Ignition-Off Draw Tests

For vehicles with or without electronic automated transmission, load-leveling suspension, or alert systems, test for college amperage IOD to foreclose impairment to most milliamp meters. Use a standard 12-volt test light and a milliamp meter equipped with two leads that can handle up to two amps. Once you lot have the equipment you need, perform the following:

  1. Verify that all electric accessories are off. Allow these to time out in approximately 30 seconds.
  2. Remove the engine compartment lamp bulb later on verifying that information technology is working by opening and endmost the hood.
  3. Detach the negative battery cable and connect the 12-volt test low-cal betwixt the negative cablevision clamp and the negative battery post.
  4. For vehicles with alarm systems, bike the key lock on the driver's door to disarm the warning. This volition stop the parking lights from flashing.
  5. Look the test low-cal to be brightly lit for upward to 3 minutes or non lit at all, depending on your vehicle'due south model and electronic components.
  6. If the test low-cal remains brightly lit after 3 minutes, do not disconnect. Instead, disconnect each fuse or circuit breaker until your test low-cal is dimly lit or off to eliminate higher amperage IOD. Once washed, it volition be safe to install the milliamp meter to check for low amperage IOD.
  7. Disconnect the alternator's wiring harness if your test light is even so brightly lit after disconnecting each fuse and excursion breaker. Call back non to disconnect the exam light.
  8. Check for depression amperage IOD by connecting the milliamp meter betwixt battery negative post and negative battery cablevision. Avoid opening the doors or turning on any electrical accessories while yous practise this equally your milliamp meter may harm.
  9. Disconnect the exam light and encounter if the milliamp meter reading is less than 30 milliamperes. If not within specifications, disconnect the 60-way connector, the 25-way connector, the circuits to the clock and radio, and the alternator'south wiring harness.
  10. Check each component until there is excessive IOD. Take notation that the exam light or meter must remain connected for all tests.

Regardless of the result of both loftier and low amperage IOD tests, annotation the following:

  • Locate the Power Distribution Center and remove the 50-amp fuse.
  • Let your vehicle an additional 25 minutes minimum of electronic shut off time if it is equipped with electronic automatic transmission and where yous suspect loftier or low IOD.
  • If your vehicle has an automatic load-leveling system and you suspect high or depression IOD, allow an additional 65 minutes minimum of electronic shut off fourth dimension.

How to Remove the IOD Fuse

Getting the IOD fuse out of its clip can be a fleck tricky. Kickoff past removing the housing top to the air filter. To practice this, disengage the clips on the left and the right front sides and the spiral that holds the retaining band. Using a tiny, sparse, or curved-tip screwdriver, pry the tabs on the left side of the opening (the plastic hinges on the right) to allow admission to the fuse.

Pull the fuse with pocket-sized pliers and make sure not to go the low-contour fuses. Supersede a new IOD fuse in the casing, put the pocket-size plastic carrier back on, and close the top of the clip. Reinsert the IOD into the fuse box past pushing the larger plastic casing back into its original position symmetrically (if not done correctly, you will feel two detents as each side of the fuse holder snaps by the pre-concur position). And so, check that all accessories and functions are back in working condition. And voila! You have successfully replaced your diddled IOD fuse.
