That cause our trucks aren't really obdII

 

When they were 1st built, your are rite about ob1 . I ordered my truck from ford. Rec,d it in April 1995. In late May I had the injector O-rings replace because it smoke like crazy when starting it cold. When ford did the O-rings they also updated the PCM to OB11. So if the truck went back to ford for warranty work or complaints on how they ran Ect. they usually were updated to OB11. Now I,m waiting for help to-morrow Friskyjake

 

They just open the OBDII port that doesn't make it obdII. Most dealers did this so they didn't have to use the old outdated system.

 

a quick question for Mike I hope your still on.
Is there a chance auto ingenuity wont work on my 97?

 

Are you setup the way Glenn post in post 8

 

You may be rite. I was there when they updated mine. They hooked up a computer to my ob11 port under the dash & flashed [ or whatever they did} & stuck a decal to my firewall which have a bunch of # ect. Is this what you meant by opening a port? So what is the difference in the ob1 & the ob11? This is very interesting no know. Thanks Friskyjake

 

Differences between OBD 1 and OBD 2 ? Scan Tool Center

 

yes Mike exactly

 

Another thing to consider is that if you have an ACPM, I have been told that it has to be disconnected to get a good read on the OBD 2.

 

mkieth54 So what is ACPM? {110v personal ?} Not sure.

 

It's a auxiliary idle control

 

Thank you for responding. All these shortcut terminologies make a old man wondering. I don,t have that unit on my truck. Thank you again.

 

I'm pretty frustrated right now. I really wish i could figure it out. ae says they have seen this in the past with a flashed pcm, whatever the hell that is

 

Either a dealer or a tuner 'updated' your PCM but I never heard of this causing ae not to work.

 

what would you guys do at this point? i don't want to give up
