Like the title says I have a weird issue. An e I plug a scanner into the ob2 port my truck will idle fine it'll it starts the scan then just shut off. It'll do it everytime old hot don't matter tried diffrent scanners same results I tried the search bar but nothing comes up with the same problem.

Thanks

 

Need a nicer scanner, or the scanner cord has a short in it.

 

I've tried diffrent scanners an all have been for diesel even my buddies snap on scanner will make it die

 

Ford OBS trucks need the scanner setup different than most diesels. It uses an old "PWM" protocol to connect to the PCM.

Is your buddies diesel a Ford OBS (94-97) or something different?

APPLES <--&--> ORANGES

 

Oh no he doesn't have a 7.3 he's got a worthless d-max only thing it's got going for it that it is a six speed. He use to work on nbs 7.3&6.0s an it's his scanner.

 

That's what I thought. Think I remember you have to set it up for non-OBDII protocol but I'll let others chime in that have actually had to set one up. Instruction manual is your friend when trying to get a scanner to work with these rigs.

 

Thought it was obd2 plug in port is in the truck on passenger side

 

The plug is called the OBDII port, the engine doesn't speak the OBDII language. You have to plug in the scanner to the port, but then adjust the settings so it reads a non-OBDII engine. The plug has nothing to do with what language the engine communicates in.

 

Is this on the 97 ?...

 

Yes 97 f-250. Sorry please forgive my ignorance I'm use to gas engines it's my first diesel. I'm finding out that it's a whole diffrent beast.

 

It should be OBDII already ...

 

What I had thought but like I said diffrent beast then I'm use to so It would surprise me that I didn't know something. Theres nothing wrong with the truck that I can tell but wanted to double check but it keeps cutting off when the scan starts

 

If your just checking for codes the truck doesn't have to be running. It only needs to be running to see live data

 

Great Idea....

 

My scan gauge will reset codes at 70mph.
