  • Easy to use reader.
    I use it on my 1987 IROC Camaro which has two methods of diagnosing the Engine lights. One is a jumper cable, the other is using a tool such as this. All I have to do is pop it in, turn the key to ON, and read the codes. Very simple, very light, does not require a degree to use. The booklet that comes with it has a list of codes, their descriptions, and how to start collect the codes from the ECU. However, any GM car repair manual will/should have the same list. It is cheap, and it does what I need it to do.
  • Nice gadget
    This product is handy to have to locate a source of a "Service Engine Soon" light. It merely grounds the ECM engine pin or the ABS brake pin which are located in the diagonsitc port under the dash and causes the SES light to flash the ECM codes. A paper clip can do the same thing but the GM Code Reader is better because it a accurate and positive fit. The GM Code Reader will only indicate the ECM code and will not tell you anything else after the SES light is seen. Then you must determine what is causing the code to appear. This product is a OBD-1 Code Reader for 1982-1993/4 vehicles and is not the OBD-2 Code Scanner that must be used on the 1995 and later vehicles. The latter has a screen and gives more information with the code. Using the GM Code Reader is a fifteen minute job and gives you a good starting point for locating the trouble and saves you $90 or more by not requiring a so-called "professional" auto mechanic do it for you. It will more than pay for itself after you use it one time. <br /> <br />The first code I observed when I first used the GM Code Reader on my 1991 Chevrolet S10 Blazer SUV was the infamous Code 32, a EGR system malfunction. It apparently was a false code or a temporary code because I did not do or replace anything to correct the problem and the "SES" light has never returned.
