INNOVA 3123 GM OBD1 Code Reader, Windows XP

Got it for a 1992 Ford F150 and it worked like a charm reading codes. Was a little hard figuring out how to connect to the connector on the truck but once we figured it out, it was able to tell us what errors the truck had quickly.

This tool is a must have if you're diagnosing an odb1 Ford. Infinitely easier than the paper clip trick. I'm not worried about the device breaking, however if you leave the manual in your glovebox over summer the binding may come undone and the book fall apart on you

It do wat is subpose to do, I used for my For F150 1983

I have a 1989 Corvette that was showing a "service engine soon" light. I've got an OBD2 reader, but that's no use on a car of this age. This unit worked exactly as advertised. I plugged it in, and then read the blinking dash light to get the codes. In my case, the accompanying book indicated I had a problem with my mass airflow sensor and/or my manifold absolute sensor. I cleaned the MAF sensor with the correct cleaner and found that my year's engine does not have a MAP sensor. I also replaced the two relays that control the MAF sensor. No more "service engine soon" light!!!!I read negative reviews of this device and how the pins will can come loose and retract into the plastic housing making the device useless. Not sure if they've improved their manufacturing, or I got lucky, but mine is fine. Finally, The internet is full of very good advice on how you can use a paperclip to jump two of the pins on an OBD-1 port and read the blinking code on the dashboard of these older vehicles. I completely agree that this will work and save you the cost of this device. However, the gymnastics (for me) of holding a paperclip precisely in place (with one hand), while turning on the key and reading (and writing down) the blinking light codes up on the center of the dashboard (with the other hand) made this device an easy decision. Maybe if I had a pickup truck or some other large vehicle with plenty of room in the interior to maneuver, I might have gone with the paperclip.

1989 Ford. Product worked perfectly. Connected to OBD 1 and gave me all the active faults. Very good product

Believe the reviews. The pins push right into the unit as soon as you try and connect it to car.I purchased the extension cable being I want to be inside the car with it running to check codes. Here is what I did to use the reader successfully:-Remove to battery and battery door-Using a flat head screwdriver carefully split the case on the scanner-Using small needle nose pliers, hold the pins from the back on the inside of the scanner-Carefully and slowly work each pin back thru the top of the scanner case and into the extension cable-Temporally electrical tape the scanner case back together-Insert battery and replace battery cover-Test unit on vehicleIf the scanner works correctly at this point, you can remove the tape and use some kind of adhesive glue around the edge of the vase to permanently reattach it. As long as you dont remove the extension cable, it will work as intended.The book of codes and instructions that comes with it is very good. Lots of detail and explanations. Without the extension cable, one would have to figure a way to glue or permanently afix the pins to the top of the case. Doesnt seem like an easy or lasting way.My take:Get the extension cable, follow some form of my instructions, be happy with scanner.

Obd1 scanner works great cheap in price easy-to-use

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.
