Vehicle ID Block corrupted or not programmed
Does anybody know what this means? and what would be involved in fixing it. also we have p1635 (tire/axle ratio out of acceptable range) that pops up first. and then p1639 (Vehicle ID Block corrupted or not programmed). I'm trying to buy a new 2000 SUV and would like to know what im getting into before I buy it.

Someone probably messed with the ECM (chip, programming, etc.) These errors could be the tip of an iceberg, and there might be some other issues. ECM may need to be reprogrammed or replaced. Get a dealer and a junkyard quote.

I hadn't thought about it till the other guys brought it up, but I wonder what errors you get when you replace the instrument cluster? If it's possibly related to that, then you may not be able to trust the mileage.

Those codes are just what the discription says.
The softwere block in the program has id data on the gear ratio and other Id info.
If it were messed up even more the truck would not start.
The fix is to reflash the PCM.
For this the dealer has top go to the "as built" data base to retrieve the info the truck was originally buit as.
If there are mods where the gear ratio has bee changed, the speedp won't be correct.
A dash HEC dignostics will also show a fault code pointing to the same PCM codes but by another code number.
If this truck is a dealer sale, tell them to re-flash or no 'buy'.
It cost them nearly nothing to fix this as a sale item.
Normally you need to have this fixed if you have inspection or it fails from just having the light on.
You buy without having then fix this, then you pay for the same action, later.
Tell them to take $150 off the price and you get it reflashed at some other dealer.

You think this is bad? There is an owner in the UK that has an 04 with a fault and no one will touch the truck! It's an expensive looking lawn fixture until it gets fixed.
