Speedometer off

[JBrake]

Does anyone know how to reset my 2002 KJ speedometer to taller tires. I'm running 18x70x255 (31")

The Dealers can program it...I think in the BCM but I may be wrong!

It is called "pinion reset"

Thanks, I know it can be done on some vehicles

Need a DRBIII or compatible, look for pinion factor in the trans menu.
