INNOVA 3123 GM OBD1 Code Reader, Windows XP

I recently purchased a 94 Bronco that has some issues after warm up. I used this to read the codes after the check engine light came on. The codes helped me diagnose my issue. Works as advertised. You can use it to read stored codes as well as the codes that are being accumulated while the truck is running. Very easy to use with very complete instructions as well as a complete listing of what all the codes indicate.

Works good I recommend

This is for OBD1 cars up to 1995. 1996 and newer will not work with this. I got this for my 1995 Mazda 626 4-cylinder automatic (with Ford EEC-IV). It worked like a charm the first time! You can also use this to clear continuous memory codes (Keep Alive Memory) which is nice. You can also use this to run a cylinder balance test, KOEO test, and KOER tests if your car is capable of it. This thing has been the best $25 I spent for my 626. There are video tutorials on YouTube for using it with your Mazda 626.If you're wondering if you should get the extension cord you should if you can afford it. It does make things like ten times easier with the live test inputs you might have to do like turning your steering wheel, pressing the clutch, brake, or other inputs in order to run the KOER test. In order to do those inputs you need to see the prompt code to do them. That means running from the side of the engine bay into the car to perform those inputs (within 2 seconds of being prompted). It's easier if you're sitting in the seat with the reader in your hand, not feeling like Wylie Coyote running around your car. Get the extension cord if you plan on trying to run the more advanced diagnostics.The manual it comes with is thick (only because it's split into multiple languages) and might take you reading a couple times to digest all the info and procedures. Out of the whole manual there's only about 10 pages that you have to read and the rest are code descriptions. They have a long list of compatible cars and the Mazda 626 is not listed. I even emailed Innova about it and they didn't seem too interested in adding my car to the list because it's only for specific years (1993-1995), specific engine (2.0L), and transmission (Automatic).If you currently have to count the check engine light flashes and your car is NOT OBD2... then you'll want to see if you can use this because it's a huge time and frustration saver. Worth every penny.

Once I got this hooked up correctly, it gave some codes. the truck connector plugged in several different places on the reader. After much looking online, I got it right. What I missed and was not in the book. The ghost outline of the truck connector is on the face of the reader. There probably should have been a picture and instruction showing this.

Instruction book is great

Purchased as a gift for my son who got a “hobby” truck (an old F-150) to fix up that’s pre-OBD2. He had an OBD2 reader but of course could not use it on this old truck. Although OBD1 info is limited, he uses it primarily to check up on smog/emissions stuff (that’s just about all it can do as electronics used to be very primitive on these older vehicles) and he needed a Ford specific reader. He reports it is working well but that the prongs used to connect to the OBD port are a little “weak” so you have to be very careful when plugging it in to avoid damaging the reader.

We have all kinds of scanners in our shop....none for the 1990 vehicle. This was great, let us know our codes!

READ BEFORE PURCHASE!!! Then 3145 model I purchased did not work on my 93 f150 4.9. The male pins on it do not match up the the female pins on my trucks data tes t plug. Made 3 jumper terminal wires with males on one end and females on the other ends I tried every (9) combinaton. Nope. Called Innova tech support. They said it ONLY works with 91-94 fords with the 7.3l engine! Page 7 of the owners manual actually list my particular truck but was told that was an error. I asked what model reader do they have that would work for my truck and was told that they do not make one!!! All the reviews must be a conglomerate of all their readers for varoius other vehicles.
