yeah, that looks like it would work, also.

First, sorry if this has already been asked, but I searched and found nothing.

I did this 3-button to 5-button DIC mod on a 04 GP that had ~ 80k miles on it. The 5-button DIC had under 10 miles on it when I installed it.

Still have the 3-button DIC hidden away racking up miles. As far as I know it matches the BCM. The 5-button has over 12k miles now.

Question - how can I get the 5-button DIC odometer updated (reprogrammed) to match the BCM as well?

Right now I always take the 5-button out and put the 3-button back in when I take it in for oil changes. I don't want the service records to show the lower mileage because some database somewhere might show this as a rollback of the odometer.

I'd like to get the 5-button mileage to match the car's actual mileage so I can stop doing the swaps.

I talked with the service manager at my local GM dealership. Said he would research it and get back to me. That was over 3 moths ago...
