I ended up purchasing a Foxwell NT644 Pro. It could not reset the service interval.
It did have an option to revert to before the last service confirmation. Last service I did was B.
I then tried confirming service was done and it was able to reset the B service I did maybe 3 or more years ago!
So now it says Service A is due in 365 days. Should be B, but I’m not complaining. No messages for the dealer to offer service for $$$ while it is in for the front driver and passenger airbag recall.
I believe the system will not allow reset if there is an error/code in the instrument cluster module. I scanned the car and none found there. The failure message also notes it can not reset if it has been less than “100” since the last reset. I am guessing this 100 is km, most likely, or mi, less so. The units were not defined. Since the car has been stored it has not been driven and fails this.
