9004307A2022-09-26. Service bulletin. EQUIPMENT; ENGINE. TRANSMITTER, Integrated Key FOB Due to a global semiconductor shortage, service availability of this part is limited. To maintain production and service requirements, FOBIKs affected by the shortage will be available on an ?as required basis?. This FOBIK should only be ordered in the event the vehicle is inoperable, and there are no other FOBIKs available. It is requested the customer uses their spare FOBIK until supply is once again available.
