The vehicle system check provides the status of the following MyKey® parameters:
- MYKEY DISTANCE - This odometer only tracks mileage when a MyKey® is used. If mileage does not accumulate, the intended MyKey® is not being used. The only way to reset this odometer to zero is by clearing the MyKey®. If this odometer is lower than the last time it was checked, the MyKey® system has been cleared.
- MYKEY(S) PROGRAMMED - Indicates how many MyKeys® are programmed to the vehicle. It can also be used to determine if a MyKey® has been cleared.
- ADMIN KEYS PROGRAMMED - Indicates how many admin keys are programmed to the vehicle. It can also be used to determine if an additional spare key has been programmed to the vehicle.
Refer to the Owner's Literature for information on accessing the MyKey® system status in the message center.
