DTC B27A5: Open in Front Floor Electrical Key Oscillator Circuit: Description
WARNING: This page is about a different variant/trim than selected.
The certification ECU (smart key ECU assembly) generates a request signal and sends it to the No. 1 indoor electrical key antenna assembly (for front floor). To detect the key inside the cabin, the No. 1 indoor electrical key antenna assembly (for front floor) creates a detection area in the cabin.
DTC B27A5 is detected by the certification ECU (smart key ECU assembly) when an open circuit occurs between the certification ECU (smart key ECU assembly) and No. 1 indoor electrical key antenna assembly (for front floor) terminals (between CLG5 and ANTE5, or CG5B and CLGB).
