Hi its been a while since my last Mitsubishi. also have not used the 708 for quite some time now, I mostly use the Mitsubishi mut3 . normally autel tools don't require a pin code on Mitsubishi and Honda. first you need to re-write the vin number if it doesn't take the first time try again until it does, then go to immobilizer function\special function or misc function and register keys. if by any chance the 708 can not do it and you happen to have a t-code pro or any other similar tool then here is the codes.  I believe 1530 does all vehicles for usa region mmna. hope this helps good luck.
