The OBD port is powered by a 15A fuse which is typically located in the power distribution center, near or under the hood of the vehicle. The exact location may vary depending on make and model of the car. It supplies power to various components such as ECU, transmission control module, ABS system etc.
Depending on your vehicle’s make and model, you can find this fuse using either its label or its color code or both. It is important to check that fuse before attempting any type of diagnosis with the OBD port because without it no communication could take place between diagnostic tools and other modules in the car.
The OBD port on your vehicle is powered by a fuse. This tiny component is what sends power from the battery to the diagnostic port so that you can access information about your engine, transmission and other components of your car. Without this simple yet important part, it would be impossible to get useful data while troubleshooting or tuning up your ride.
Make sure you know where this important piece of equipment is located in order to keep it safe and running smoothly!

Where is the Fuse Located for the Obd?
The OBD fuse is typically located in the interior fuse box, which can be found underneath your dashboard. It’s usually a black or grey rectangular box with several slots for different fuses and relays. To locate the specific OBD fuse, you’ll need to consult your car’s wiring diagram or service manual.
Once you’ve identified the correct slot, use a fuse puller tool to remove it from its slot – never attempt to lever out a fuse with other tools such as screwdrivers! If your vehicle doesn’t have an interior panel for easy access to these components, then chances are that the OBD port is only accessible from under the hood of your car. In this case, you’ll need to locate either the battery junction box (BJB) or power distribution center (PDC), both of which house numerous relays and fuses associated with various parts of your car’s electrical system.
The exact location of each will vary depending on make and model; again, consult your owner’s manual or wiring diagram if necessary.
Why is My Obd Port Not Getting Power?
One of the most common problems experienced with an OBD port is lack of power. This can be caused by a variety of factors, including a faulty connection or even damage to the OBD port itself. If your OBD port is not getting power, you may have trouble reading any diagnostic data from it.
The first step in troubleshooting this issue should be to inspect the wiring that runs between your car’s computer and the OBD port itself. Check for loose connections or frayed wires, as these could cause a break in continuity which would prevent power from reaching the port. Additionally, if there are any visible signs of physical damage to either the wiring or connector ports on either end then they should be replaced immediately as this will restore functionality and allow for diagnostic readings again.
Finally, if all else fails then it may be necessary to replace the entire OBD unit in order to get back up and running properly again.
What Would Cause the Obd2 Reader to Not Work?
Given the complexity of modern car engines, it is not uncommon for an OBD2 reader to fail to work properly. There are a variety of reasons why this might happen and they range from incorrect installation or connection issues to hardware malfunctions. In some cases, the cause may be something simple such as a bad fuse or loose connection causing the power to not reach the device.
Other times, it could be due to incompatible software that fails to recognize certain data codes or communication protocols. It could even be caused by an internal error in the OBD2 reader itself, leading it not being able to read vehicle information correctly. Whatever the case may be, diagnosing and fixing these problems requires a professional mechanic with access to proper diagnostic equipment and expertise on how OBD2 readers function correctly in order for them do their job effectively.
What is a Dlc Fuse?
A DLC fuse is an acronym for a Dual Element Low Current Fuse. It is a type of electrical protection device designed to work with low-current systems, such as those found in computers or electronic circuits. They are commonly used in residential and commercial applications where space may be limited, because they take up less room than traditional fuses.
The DLC fuse consists of two elements: the first element detects current overloads while the second acts as a backup should the first element fail. They also have higher interrupting ratings than other types of fuses, which can help protect equipment from damage due to short circuit events or high voltage surges. Additionally, these fuses are self-resetting after power outages so no manual resetting is required when power returns – this makes them ideal for protecting sensitive electronics from unexpected power fluctuations or outages.

Data Link Connector Fuse Location
The data link connector (DLC) fuse is typically located in the engine bay, usually on or near the fender. It provides power to the vehicle’s diagnostic system and needs to be replaced if it becomes faulty or blown. In most cases, this fuse will have a red cover with a white label indicating its purpose.
For further information about your specific vehicle’s location of the DLC fuse consult your car owner’s manual or contact an automotive technician for assistance.
Conclusion
This blog post has clearly demonstrated the importance of understanding what fuse powers the OBD port. From knowing why it is important to having a clear understanding of what fuses are used, this article has been an informative and helpful guide for anyone looking to learn more about their vehicle’s electrical system. It is essential that car owners have a basic knowledge of how their car works, including its electrical systems, so that they can properly maintain their vehicles and keep them running smoothly and efficiently.
By making sure you know exactly what fuse powers your OBD port, you can make sure your car remains in top condition at all times.
