SOURCE: My 2006 Dodge Stratus is

my guess is the ground to the rear lights is bad and when you hit the brakes the voltage loops back into the light circuit and overloads it

SOURCE: I have a 99 ram 4x4 slt laramie dome lights cargo light and map lights dont work, replaced #12 fuse 10amp under the black fuse keeper thingy on the drivers side but it keeps blowing it some times it l

Classic symptoms of a frayed wire carrying current somewhere in the circuit, but touching metal, bare metal against bare hot wire: instant SHORT! Maybe a little spark there. Fortunately for you, you have a 10 amp fuse in that circuit which blows, and keeps the wiring from melting, and maybe starting a fire somewhere in your vehicle. If the fuse doesn't blow right away, the bare wire has moved away from contact with metal, but eventually, with enough movement it gets back into position and shorts again.
Enlightening, but not very helpful, eh? I'm afraid that's the way it is, Richard. Shorts like that can be very difficult to trace and find, without time and patience, a decent understanding of auto electrical systems, a wiring diagram for your Laramie, and knowing just what circuits that fuse protects.
If you have the owner's manual, it should list the circuits for that #12 fuse. I'd start with the dome lights, and remember, the door switches are part of that circuit. Good luck.

I keep blowing the iod fuse

I unplugged the light harness under the hood. No success. I took the radio out and looked at the wiring harness and found some exposed wires. I taped them and no success. I've tried to look over the wires and havnt really found anything wrong. It was alos suggested to me to remove the sensors in the door jams and see if this solves the problem? The IOD sensor is controlling my overhead dome lights, my radio, and my lights under the hood and my PCU port so I can't pull any codes from the computer. Any ideas would be awesome. I'm looking forward to this forum

My IOD fuse keeps blowing

oid is there way of saying hot at times,(others use)
IOD, is correct name
ignition OFF, drain
these fuses are pulled when car leaves factory , keeping battery fresh, then put back , at dealer
the are are just keep alive features, (electroncs)
1: PCM ,memory (errors, and fuel trim learning values)
2: radio stations,
3: NAV settings;
4: all the various brains, in system, pcm bcm , tcm , an others)
Allen Turning called it a brain, so he wins, (lol)
all feature on car with LEARN in the descriptions, is this.
IOD fuse.
but you can read the schmetic right> and see what loads connect to your fuse , right? and then pull it and see if current falls to ok.
my guess, (i fix ECUs for years, and lots of controllers) at component level for 50 years. ) the electolytic caps some will go bad at too cold a temperature, good ones go to -40F or -40C (crossover) some china clones of these parts are pure rotten junk.
not even tested, there, they just clone the words, .....

finding which cap is shorting is not easy. (too intermittant, even hard for me with my fancy gear, (i have current logger, i designed)

post the real location of the fuse , a photo is best.
then we look it up
or you do it at
(google finds it in 1/10sec)
im hoping its some cheap radio doing this
so unplug it and see.
unpluggin pCM or BCM etc is not going to work, as car will not run.

i think normal current is about 0.020 amps max
ase/sae , averages. 20 mA.
blowing fuse is gross short.
i hope it says shorted,so is 1000x easier to find.

2003 pajero wiring diagram

You can invest in purchasing an online repair manual for the year, make, and model of your car; or buy one at a local auto parts center like NAPA, PepBoys, Autozone - make sure it includes wiring diagrams for the fuse panel.

Has the check engine warning light illuminated on the dash? Do you have any Diagnostic Test Code faults being generated by the OBD II system?

The Ignition Off Draw (IOD) is responsible for powering the Engine Control Module or Power Control Module (or whatever name your manufacturer gives theirs), in order to maintain its memory functions. Some recommend that this fuse be removed if the vehicle is going to be sitting for any undue length of time because of the parasitic draw of the computer and the other features, like security systems and such use as well.

Vehicles have a battery drain relay that kicks in once the battery voltage drops below a certain level so that the battery is not drained completely; making a battery re-charge viable, instead of going through the expense of having to buy a new one each time something like this happens.

Each manufacturer has specific draw test procedures to perform to properly diagnose the problem down to the component level- I really don't think that having just a diagram will suffice since the tests are detailed.

I purchased the Ford Motor Company's repair manuals that the dealership mechanic's use- for my Excursion and F-250; expensive, but then again, I do a lot of my own repairs. Especially when repair shops charge over $125.00/hour for diagnostic and repair work.

Below the odometer it indicates no fuse,

The IOD fuse is missing or burnt out. IOD is "ignition off draw" which serves as the dome lights, radio memory, locks and other things powered with the key off.

No dome light or radio

It's the IOD fuse. Trust me, I just fixed the exact problem on my '98 not ten minutes ago. The fuse is located in the fuse box inside the driver's side door. It will be the fuse on the bottom and toward the front of the panel with a black cover over it. Just pull the fuse holder straight out and snap the hinged cover forward to expose the fuse. Just a standard 10 amp automotive fuse and you're back in business!
