"A" is not a valid OBD II code. 4-65 is not either. It should start with a P for powertrain followed by four digits. When you enter the code, don't just enter the numeric portion.....enter a PXXXX where X is the numeric portion or no matches will be found.

Codes are different on the 3rd gen trucks.

Not sure OBDII has them yet.

Someone posted the codes on here about a month or so ago.
Check in the 3rd gen forums, or maybe an admin added them to the Tech Facts section.

I suspect you got an instrument panel failure code. I do not even think those are standard from year to year, but seem different based on the electronics installed.
