DTC B27A8: Open in Outside Luggage Compartment Electrical Key Antenna Circuit: Description
The certification ECU (smart key ECU assembly) generates a request signal and transmits the signal to the electrical key antenna (outside luggage). For the electrical key antenna (outside luggage) to detect when the electrical key transmitter sub-assembly is brought close to the vehicle, the received request signal is transmitted within approximately 1.0 m (3.28 ft.) of the back door. DTC B27A8 is stored by the certification ECU (smart key ECU assembly) when an open circuit is detected between the certification ECU (smart key ECU assembly) and electrical key antenna (outside luggage) (between terminals CLG8 and ANTE8, or terminals CG8B and CLGB).
