U0306 software incompatibility with FICM

[sleeps]

Any ideas what this could be?

any history like when this popped up
new FICM ?

I have this code constantly. I had SCT make me a stock file that will show my VIN so my gauges read correctly when the truck is tuned. That's when I get this code as well. Doesn't cause any problems or even throw a CEL.

 

[what a mess]

is the ficm tuned?

Each time I've seen this code its accompanied w a p1000 code...I've seem a pcm ref lash fix it..

I've also seen contribution and balance codes with it. But in both scenarios the 0306 code was first.

Did you recently install the new ficm?

 

[Zmann]

yes the ficm is tuned too.

did this happen after you tuned your FICM's logic side ?

assuming it was a tune and not a different logic side ?
