My Truck 2010 5.4L Fx4
edge CTS programmer

I just put new tires on my truck and wanted to correct the speedometer. So I downloaded the stock programming. Once complete I selected the stock programming again and set the tire size. All seemed well after initial drive last night.

This morning wake up to two codes P0605 and P1000. After reading I turned them off and went to work. Started truck up again and codes appeared.

After Lunch I will be returning all settings back to stock. I also replaced my air filter 1 day prior to updating my tire size.

I am currently waiting on custom tunes.

Do I need to try to reinstall the tire size?
leave it all stock untill custom tunes?

Any help would be appriciated.

Thanks

The p1000 is a relearn code....

The p0605 is a corrupt file code....

When changing tire size a canned/custom tune needed to be used......using stock programming it shouldnt be able to be done....

So after all this I returned the truck back to stock and still have the P1000 code (re learn). I am sure it will go away after re learning is complete.

I did not know that using the stock programming and using the custom features to modify the tire size could not be done.

thanks for the information

You can change the tire size only when a canned/custom tune is going to be loaded....
