DTC B27A6: Open in Rear Floor Electrical Key Oscillator Circuit [10/2013 - ]: 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 indoor electrical key oscillator (for center floor). To detect the key inside the cabin, the indoor electrical key oscillator (for center floor) creates a detection area in the cabin.
DTC B27A6 is detected by the certification ECU (smart key ECU assembly) when an open circuit occurs between the certification ECU (smart key ECU assembly) and indoor electrical key oscillator (for center floor) terminals (between CLG6 and CLG4, or CG6B and CLGB).
