Where is the 1994 Toyota Land Cruiser OBD port located?

I started helping a friend fix up an old Toyota Land Cruiser but we can’t locate the OBD port to diagnose its engine issues. Where is it?

Don’t worry, your vehicle’s OBD port didn’t disappear! The 1994
Land Cruiser OBD port is located underneath the hood on the passenger’s side of the engine bay in a black plastic box labeled Diagnosis. When you open the box you’ll see a bunch of pins and a chart that indicates the location of each pin—similar to a fuse box.
Newer vehicles have an OBD-II port, that’s usually located below the steering wheel near the foot pedals—but most vehicles didn’t become OBD-II compliant until around 1996.
You won’t be able to use an OBD-II code reader on a 1994 Toyota Land Cruiser, but you can still diagnose it if the
Check Engine Light is on
. If you have an OBD-II code reader, consider using an adapter so that you can plug it into the OBD-I port. Code readers are the easiest way to pinpoint the trouble codes stored in your vehicle’s Engine Control Module (ECM).
