## Overview

The Innova 3123 GM OBD1 Code Reader is a precision diagnostic tool designed for General Motors vehicles from 1982 to 1995. It safely accesses engine and ABS codes via the vehicle’s self-test connector, providing real-time and stored trouble code data. With multilingual instructions and a professional build, it empowers you to troubleshoot with confidence and avoid costly mechanic visits.

## Description

The INNOVA GM Code Reader accesses the vehicle's on-board computer to retrieve engine and electronic transmission codes and ABS vehicle computer codes. It connects to the vehicle's computer self-test connector and shows the trouble through vehicle's "check engine" light. It includes detailed instructions in English, French, and Spanish with illustrations and code definitions applications.

Review: Nice book with lots of clear ENGLISH instructions and extra general info about how the computer works etc., and a full list of codes. Unit itself is professional looking high quality gear, you won't be embarrassed to use it. (Unlike how dirt-cheap some certain orange colored tools from a certain unnamed place can appear) I bought a '93 Lincoln Towncar, and it has an intermittent MIL. It's "EGR insufficient flow" so can be largely ignored. If a couple cans of Seafoam won't cure it in the next couple of weeks, I'll replace the $35 EGR valve and/or clean the carbon out of the manifold passageways. A note about the OBDI which is what these cars have: unlike 'modern' OBDII, the MIL operates in real time. (MIL = Malfunction Indicator Light or "check engine" light) With OBDII, if the MIL is triggered, it stays on for the most part. If it's a one time event, many start/stop cycles might turn it back off, but it usually needs to be cleared. With OBDI, the light may go back out, come back on, go back out as you drive. (It does in my case) The car's computer has a stored code area, which this tester has access to, so, you can see what's triggering the MIL as it happens, AND check the stored codes too. In my case, the codes just refer to the (probably intermittently sticking) EGR valve and nothing else, so the price paid for the code reader is worth the piece of mind at the very least. As for buying the extension cable, (or not) on the Towncar, the OBDI connector is on the driver's side fender, so I can prop the tester up and read it by leaning out the window during run-up testing. It depends on where your diagnostics port is as to whether you need the extension cable. You do need to see the display during real-time testing. If you're chasing an intermittent MIL, you'll need a cable to run under the hood and into a window so you can have the tester inside while you drive and have a friend watch the display.

## Questions & Answers

**Q: Is this Bluetooth??**
A: Thank you for your question. No, the 3123 is not Bluetooth.

**Q: It does suppot my car model : opel astra f 1992 1.4si engine code: c14se, 10 pin daignostic contener ??**
A: Thank you for your inquiry. The vehicle you are referring to was built for a foreign market and cannot be read by our tools.

**Q: Will it turn off the check engine light?**
A: When dealing with an OBD 1 car, the 3123 will not turn off the check engine light. Disconnecting the battery for a few minutes, up to 15 minutes in some cases, will clear the codes. However, if the problems were not fixed, they will come back and set the service engine soon light.

**Q: so where does it show the codes at? I have an OBD2 that is right on the reader, this one doesnt have a screen, and will it work on a 96 chevy silverad**
A: Thank you for your question. No, the 3123 will not work with a 1996 Chevy. The 3123 scan tool only works with most 1981 to 1995 vehicles. 1996 and newer vehicles use OBD2 scan tools.

Habe durch das Gerät einige Euros an Werkstattkosten gespart - Natürlich muss man sich mit der Materie etwas auskennen.
