Took my truck in for service last week, reflashed runs great. I flipped the key four times to get the codes out of curiousity and guess what. P0633 comes, I am thinking whats this and rush to a dealership in the town I am at. He tells me the code, some SKIM security thing.
Well tongiht I was trying to track a bad interferance noise which sounds like a bad ground some place when my foot is on the brake. I pulled the fuse panel open to have a look and much to my surprise the SKIM circuit breaker is missing?????????? number 26 in my 2003.
I know it was there before the truck went in for service, why is it missing now. I can't imagine it's mean't to be missing after the reflash. I am thinking they want me to bring the truck back for another 100 bucks diagnotic. I got news for them

TOTAL Edit

Gonna start the service managers day off right tomorrow and chew him Edit.

 

dont you just love the service dept., i dont know where they find so many retards, and liers. Honesty goes a lonnng way with me. Sent my buddy back to diff. dealer today with this same truck, i gave him a list for them to check out. The flash you mentained, cp3 check, inj. return back check, and 1 or 2 more. I hope this works for him, has the flash and your tank line thing helped you much?

 

i've got the same code on my truck too. say there is a fuse gone in the panel? if so, u goin to put another one in it, i;ll check mine, and try it if u do...
