Playing around in the truck I decided to do the cluster test. Well got three codes,
0D-35 PRNDL switch input circuit open
A7-65 VIN checksum error
AA-65 PCM messages not received
Anyone have any ideas what to look at to correct these. The codes are activate I think because cycling the key and redoing the test increments the key cycle numbers.

Oh and not my rig just asking for someone. -

I'd reset the computer and see if they still come up because it doesn't sound like they are anything seriously wrong with the truck. If it was my truck; I wouldn’t even worry about it. The computer will retain codes even if the problem was corrected, or it only happened once. -
