Hi All,

I have a 2004 Ram 2500 HO CTD SRW SWB. I'm showing a fault code P0633.
Does anyone know what that is?
I just had the truck to the dealer last week to replace the transfer
pump. They also listed on the work order that they re-flashed the
truck. I would assume that re-flashing would clear any old codes so
this must be something new since last week.

TIA,

SKIM (Sentry Key Immobiliztion Module) secret key not entered. Do you have
the Sentry Key (big fat gray key)? If so, it's no longer enabled. If not -
the dealer enabled the SKIM feature in the ECM accidentally.

Hi Tom,

Thanks for the reply.
Yes, I have the fat gray key. Is this anything to worry about or
should I take it back to the dealer to get it re-set?

Yes, you should go back. Your Sentry Key system isn't operative - if
someone shoves a screwdriver into your ignition and turns it, the truck will
start.
