DTC B27A8: Open in Outside Luggage Compartment Electrical Key Antenna Circuit: Description

The certification ECU (smart key ECU assembly) generates a request signal and sends it to the outside electrical key oscillator (for luggage compartment). To detect the key near the driver door, the outside electrical key oscillator (for luggage compartment) creates a detection area towards the area approximately 1.0 m (3.28 ft.) from the luggage compartment door.

DTC B27A8 is detected by the certification ECU (smart key ECU assembly) when an open circuit occurs between the certification ECU (smart key ECU assembly) and outside electrical key oscillator (for luggage compartment) terminals (between CLG8 and CLG3, or CG8B and CLGB).
