Where is the 1994 Jeep Grand Cherokee OBD port location?
I recently purchased an old Jeep Grand Cherokee that I’m planning on fixing up, but I can’t find the OBD port to save my life. Where is the OBD port located on a 1994 Jeep Grand Cherokee?

The 1994 Jeep Grand Cherokee reportedly has not one but two OBD port locations. That’s right—you can find an OBD port located on the driver’s side right above the brake pedal and under the hood on the passenger’s side next to the powertrain control module (PCM). Considering your Jeep’s model year, you also likely have an OBD-I port as all vehicles manufactured after 1996 come standard with an OBD-II port as mandated by federal law.
The OBD or On-Board Diagnostics port is a critical onboard computer system that monitors vehicle data such as emissions, mileage, and speed, along with other various other vehicle information. The main difference between the first and second generations of OBD systems is that the OBD-I system was usually externally linked to the vehicle’s console, while the OBD-II system is now a part of the vehicle itself.
So now that you know where the OBD port is located in your 1994 Grand Cherokee, you’ll need to use an OBD-I scanner to uncover any possible problems you may have with your mid-size SUV. If you understand car OBD codes, just insert the scanner into the appropriate diagnostic connector and you can start repairing!
