THEFT DETERRENT / KEYLESS ENTRY: SMART ACCESS SYSTEM WITH PUSH-BUTTON START (for Entry Function): B27A7:
Open in Inside Luggage Compartment Electrical Key Oscillator Circuit
B27A7 - Open in Inside Luggage Compartment Electrical Key Oscillator Circuit
DESCRIPTION
The certification ECU (smart key ECU assembly) generates a request signal and sends it to the indoor electrical key oscillator (for rear floor). To
detect the key inside the cabin, the indoor electrical key oscillator (for rear floor) creates a detection area in the cabin.
DTC B27A7 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 rear floor) terminals (between CLG7 and CLG6, or CG7B and CLGB).
