When Monitored
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The DTC is monitored during a valid localization period. A valid localization period starts when the vehicle had been stationary (ignition off) for 19 minutes and is then driven at speeds greater than 15 mph. It ends when all sensors are no longer sending LOCALIZATION messages.
