I have a 1715 programmer and I keep getting the p1635 code. Tire/axle out of acceptable range. What does that mean???? Thanks

 

This Diagnostic Trouble Code (DTC) indicates the tire and axle information contained in Vehicle ID block (VID) does not match vehicle hardware.

CAUSES:
Incorrect tire size
Incorrect axle ratio
Incorrect VID configuration parameters

Does your programmer allow you to change tire size and gear ratio settings in the pcm? Maybe your settings are off and causing the code. I have never used the 1715 programmer, so I am not sure. Hope this helps some.

You must have larger tires than stock.Find the larger tire OAD in inches and put that number into the tuner.The 1715 gives an option to do that. Your speedo will change too because it was off with the larger tires.
good luck
