Looking at diagnostic scanners for OBD1 and OBDII

Recommended Posts

I'm looked for a good code scanner. I'm fairly new to codes scanners so I'm not too sure what they can and cannot do. Basically I need one that will do my 510 ('91 KA24DE), acura CL and friends and relatives cars.


If the scanner says it reads OBD1 and it gives a list of makes it reads, will it read all OBD1 or just the ones listed? Do I just need to buy the correct connector to read other OBD1's not on the list?


I was looking at the Equus Innova 3140. Anyone using one of these on their OBD1 Nissan? Are they any good?


What scanners are you guys using?

I've have the 3140 at work. It works well for OBD2. Never used it on a OBD1 vehicle because I didn't have the right adapter for my Z32. I use different Nissan specific software for it anyway.

The problem with OBD-1 scanners is that you need vehicle specific connectors.

Whereas OBD-2, its a common DLC(Data link connector.)


If only using the reader for codes-anything will work. Don't go all out.

But if you want one to watch data stream and freeze-frame data, spend some extra money.


Blue Point/Snap-On have a neat little scanner.

Not too much money for what it can do.

Pay cash to a Snap-On man, and it just dropped price by 30-50%.
