In contemporary cars, the fuses perform an important function in protecting the electrical system from faults.
The IOD (Ignition off Drawer) fuse is important for many Chrysler products like Dodge, Jeep, Fiat, and Ram.
Knowing its importance, the reasons for its failure, and diagnosing problems will help you understand this case.
In this article, we will discuss the significance of the IOD fuse.
We will also discuss common attributes that reveal a failed fuse, and how to proceed as you attempt to fix or even replace the blown fuse.
The IOD Fuse – What is it?
The IOD fuse is installed in vehicles to supply power to the Body Control Module (BCM) when the ignition is switched off.
The BCM carries out several functions in the car and these include among others. It is also used in lights, security door locks, and the car radio.
However, once the IOD fuse is blown it becomes a sad failure for its users.
It can cause numerous malfunctions that electrical circuit problems can cause and that’s very annoying to the car owners.
Common signs to know if an IOD Fuse has blown
If the IOD fuse blows, you may find that a few functions are impaired.
Here are some common symptoms to look out for:
Nonfunctional Headlights
The likelihood of you noticing some faulty lights will be quite accurate.
For instance, the headlights even with the key removed from the ignition would be unable to come on or go off, as expected.
- Inoperable Door Locks: The lock switch of the door might get damaged. It would not allow you to lock or unlock the doors effectively.
- Key Fob Malfunctions: This will entail that the key fob may break down completely. It will not be possible to carry out either a remote locking or a remote unlocking of the vehicle.
- Radio Problems: There may be a problem with the radio either in the situation. Where it will not come on or it may misbehave in such a manner that even when the door is opened it does not go off.
- HVAC Control Troubles: Hesitation may also be experienced in the heating or air conditioning control sections.
- Instrument Panel Trouble: The average user may find that the vehicle’s instrument panel warns with an engine light or other gauges even after being switched off by the other system in the vehicle.
What to do with a Blown IOD Fuse
If you suspect that your IOD fuse may be blown, follow these steps to understand how you can diagnose the problem:
- Check the Fuse: Make sure you locate the IOD PDC fuse that is placed within the engine compartment as instructed in the manual.
- Do not be alarmed about The Blown Iod Fuse: Take out the fuse and examine it to see if it has been burned or has a wire damaged inside it.
- Do not be alarmed about the blown fuse: If the blown fuse is a tangible issue, replace this with the same ratings as that of the broken fuse. In most Chrysler vehicles this fuse rating is the 20amp fuse.
- Validate the Electrical Systems: After replacing the fuse, the malfunctioning electrical systems are tested for functionality.
- Monitor for Recurrence: Pay attention to whether the new fuse blows again. If it does, there may be an underlying electrical issue that needs further investigation.
Replacing the IOD Fuse
Changing a blown fuse of the IOD space in the system is an operation that anyone can perform at home.
Below is a detailed process on how to change the Chip by yourself Step by step:
First, make sure that the vehicle is shut down and the keys are out of the vehicle.
Then open the latching or the trailer connector under the hood and Find the fuse holder on the driver’s side and the mini box on the passenger side.
Then with the help of fuse pullers or needle-diagnosed pliers, take out the fuse that has blown out with due consideration.
Place the replacement fuse of similar rating in amperage to the ‘head’ slot (this is normally rated 20A).
Fasten the hood and covers of the fuse box & try turning on the vehicle, check all electrical components once if the systems are working normally.
Why You Should Always Disconnect the Battery
This usually includes a negative cable on the battery.
In most cases, the negative battery cable gets disconnected after every step before the engagement of screws Such as installing the stereo.
Most of the electrical components are through bolts or interfaces and such installations.
It may look easy but it can generate unfathomable issues if the battery hasn’t been shut down.
Conclusion
In conclusion, among the various fuses and fuse holders within Chrysler, Dodge, Jeep, Fiat, and Ram’s electrical systems, the IOD fuse is extremely important.
It is quite useful to understand the symptoms of a blown fuse and be able to expeditiously find and interchange such a fuse.
And always, when working on the electrical parts within the vehicle. Do not forget to disconnect the battery to prevent accidents and damage.
With this knowledge, you can confidently address any issues related to the IOD fuse and keep your vehicle running smoothly.
