So, I was driving to work this morning, and all of a sudden I get 4 warning lights come on, no power windows, no speedo, no power in the power point and no heat. I get to work, shut the truck off, turn it back on again and everything goes back to normal except the CEL is still on.

So I disconnected the battery to reset the PCM, and eveything is fine! Anybody have any ideas on what the heck happened? I am just wondering if this is going to happen again.

BTW, it's a 2006 QC 2WD 4.7L.

 

on the way home stop at one of the auto parts stores that do FREE scans check the history for the code, PS never erase a code without first recording the code #.
do you have a remote starter or aftermarket alarm?

knowing the code isstep 1

 

I thought i was the only one! That happened to me too! I brought it to the dealer and they said my PCM was fried....they installed a new one and it hasn't happened since!

 

Didnt Shibby have this happen with his FCM although his guages, etc never came back?

 

Yea bolt I believe you are right
