The analog to digital converter in the ecm died ?

how do you fix that? i have that come up on my direct scan too.

 

[turbot2112]

do you think that would cause really messed up readings on directscan. thanks

Pull the eprom out, then the Netres, and then unplug the ecm.
Grab new ecm and do the reverse of the above.

As far as I know the GM A/D chip is custom, and about the only way to get one is to desolder it from another ecm.

And DS reported this?.
I wonder what DS sensed to report that.

With all those failures, I'd suggest re doing the DS connections. Something is amiss, and it's likely not your car.

Now that's a combination.
DE means DFCO, Decleration Fuel Cut Off, and that the injectors are off. If you car does run with that lit, then DS is seeing something wrong, or a bad ground. Clean the edge connector again, and the grounds, and see whatcha got.
