Error reading, OBD ll scanner.

Hi, all!
I have an OBD ll tool that I had been using on my '96 Chev. PU. I've never had any problems with it. I plugged it into my son's 2008 Chev. Malibu to check codes because he's getting a "check engine light" and all I keep getting is an error message after the scan. Any clues? Should I try actually running the engine or would that screw up the scanner? Thanx!

You should have key off when you plug it into the connector, then key on, and set the scanner to scan for codes. And yes you can run the engine if you want live data.

If it still won't recognize it, it may be an older OBD II that needs a software update. Those are usually available online from the company that mfgs the scanner.

It's pretty old, I dunno, 12 - 15 yrs? How could you get a software update into it? Guess I gotta get ahold of the manufacturer if they're still in business

C'mon, OP, simply drive to any parts store and have them read codes.
Or, your vehicle OBDII port is bust. Or, it really needs to be "wiggled in", as on my son's Mazdaspeed. There, slightest connector looseness will disconnect the scanner. My scangauge is about 10 yo too, and still works on any car.

Mini usb port. If it doesn't have a cable on it or computer software you may not be able to update. Google your scanner brand and model #.

Are you sure you don't need just a OBD reader for a '96? I know there was a cut off year where the OBD II won't work on older vehicles but I am not versed in when that was only that it won't work on a '92 T-bird. Might be worth checking.

Ron53... it works on his '96 but doesn't work on the 2008 model, which is what he's trying to scan.

I see I misread what he was trying to do. I was thinking he was mistaken on the unit he was using. My bad.

I do that all the time when my brain is somewhere else.

Thanx for the response guys! The tester is an Actron CP9035 and the date of publication of the manual is 2001 so I think it should work. My son did have the car checked and did get the codes but I wanted to check for myself to see if the problem was still there and possibly reset the control module. We tried 3 times and every time got the error message.

Ok, I just saw, on another forum, that beginning in 2008 all vehicles are to be can compliant which would make my CP9035 outmoded and according to Actron can't be updated. Would have to buy a newer OBDll reader with can protocol.
Thanx all!

Make sure there is power to the OBD data connector. Blown fuses wreak havoc with scanners.
