There is a self test to find this.
With the ignition off, depress the "trip odometer reset button". Hold it until Sof and a number comes up. That is the current software version. Then release the button and it will give a DTC. This code number is what I need. It will be 400.1 or 200.6 etc.
This self test may make it work again.
