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

WARNING: This page is about a different car, the 2010 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

The certification ECU generates a request signal and transmits the signal to the electrical key antenna (outside luggage). The electrical key antenna (outside luggage) detects that the electrical key is brought close to the vehicle, and when a request signal is received from within 1.0 m (3.28 ft.) of the back door, the signal is transmitted. DTC B27A8 is stored by the certification ECU when an open circuit is detected in the circuit between the certification ECU and electrical key antenna (outside luggage) (CLG8 - CLG5, CG8B - CLGB).
