Does anyone know which scanner out there would be suitible for home use ? I have a 94 Grand Am and a 2002 Corvette Coupe and was wondering which company and model would be the one to use. I would assume that one with software that could be updated would be the most useful. Thanks Nick :seeya
You will need two different scanners. For cars 1995 or older, there is no set standard. Most GM vehicles of the early 90's used the ALDL bus. You can do a search for this bus on Gran Am web sites or LS1.com.
1996 was the first year for OBDII. Each car company uses a different OBDII interface. Their are at least 3 different ones.
It really depends on what you want to do with the scanner. If you want to monitor a lot of stuff, then you will need a PC based scanner. A simple hand held one may not do everything you may want.
One factor: many scanners (X-Ray among them) can scan both OBDII and older vehicles. Most of the home scanners will scan ECM readings only (engine stuff), and will not scan transmission readings. This can be important if you have an automatic with a sensor problems (pressure or shaft speed). Not an issue on my 6 speed couple, but has been an issue on our Suburban with electrically controlled shift points.
