Car theft is a persistent concern for vehicle owners, and modern thieves are increasingly sophisticated, often targeting the OBD2 port as a gateway to bypass security systems. For owners of the 2018 Toyota 86 (and similar models), understanding the 2018 86 Obd2 Connector Location is the first step in taking proactive measures to protect your prized possession. This article will guide you on locating your OBD2 port and explore effective, free methods to deter thieves by limiting their access.
The factory OBD2 port in your 2018 86 is typically designed for easy access, primarily for diagnostics and emissions testing. However, this accessibility can be exploited by criminals. The port is usually held in place by simple clips, making removal surprisingly easy. By understanding this vulnerability and the 2018 86 obd2 connector location, you can implement simple yet effective deterrents.
To access the OBD2 port, you’ll typically find it located beneath the dashboard on the driver’s side. In the 2018 86, it’s often positioned near the steering column. You can usually remove the port by depressing two retaining clips from the cabin side. This can often be done with just your fingers, as shown in the image below once the port is removed from its housing.
Once you have removed the OBD2 port from its standard location, you gain access to the wiring harness. This access point allows for several security enhancements. A simple and cost-free method is to physically relocate or hide the OBD2 port. By making it less visible and accessible, you can significantly deter opportunistic thieves who rely on quick and easy access to the OBD2 system.
The wiring configuration of the OBD2 port in a 2018 86 is relatively straightforward. Typically, only a subset of the 16 pins are actually used. In many models like the 2018 86, you might find around eight wires in use for essential data and power. Understanding the pinout can be helpful if you plan more advanced modifications, but for simple relocation, it’s not strictly necessary.
For those interested in deeper understanding, the schematic and pinout diagrams provide a detailed look at the function of each pin in the OBD2 connector. This knowledge can be valuable if you are considering more complex security measures or need to understand the diagnostic communication protocols.
A primary deterrent strategy is simply hiding the factory OBD2 port. After removing it from its original 2018 86 obd2 connector location, you can tuck it away in a less obvious place behind the dashboard. This simple act can be surprisingly effective. A thief expecting a readily accessible port might be discouraged or move on to an easier target if they cannot quickly locate it. When you need to access the port for legitimate servicing, you can easily retrieve it. This is especially useful if you use a range device for AFM deactivation and prefer to keep it discreet when not in use.
For an added layer of deception, consider installing a fake OBD2 port in the original location. This can further confuse thieves. To enhance the realism of the fake port, you could even wire it to provide 12V and ground, making it appear functional when a scan tool is connected. Adding resistors to the data pins can simulate the presence of communication signals, further deterring potential thieves. OEM OBD2 ports, pins, and retainers are readily available and inexpensive, making this a viable and cost-effective upgrade.
To populate the fake OBD2 port with pins to give it a more authentic look and potentially provide power, you will need compatible pins and a retainer. Parts like the WM3324CT-ND and Molex 0504208000 are reported to be compatible and can be sourced from electronic component suppliers.
Important Warning: Do Not Reverse Polarity
While the idea of reverse polarity wiring might cross your mind as a more aggressive deterrent, it is strongly discouraged. Rewiring the OBD2 port with reverse polarity (12V on ground and signal pins, and grounding the 12V pin) could severely damage any scan tool connected to it. This includes tools used by thieves, but also crucially, tools used by legitimate mechanics. You could be held liable for damages to professional diagnostic equipment.
Even with a warning cover, the risks and potential liabilities associated with reverse polarity wiring are significant and not worth the minimal additional deterrent effect.
A simple, inexpensive cover for your hidden OBD2 port is, however, a good idea. This protects the pins from accidental shorts, especially depending on where you choose to relocate the port.
Conclusion:
Securing your 2018 86 against OBD2 port theft doesn’t have to be complicated or expensive. By understanding the 2018 86 obd2 connector location and implementing simple strategies like relocating or hiding the port, you can significantly increase your vehicle’s security. These free and easy DIY methods offer a practical approach to deterring thieves and protecting your investment, providing peace of mind without the need for costly aftermarket security systems. Take these steps today and enhance your car’s defense against modern theft techniques.
