Room Oscillator does not Recognize Key [02/2014 - 11/2016]: Description

WARNING: This page is about a different variant/trim than selected.

If code verification cannot be performed in the vehicle interior, there may be problems with the communication between the vehicle (indoor electrical key antenna assembly (front floor), (rear floor) or (inside luggage compartment)) and electrical key transmitter sub-assembly, or the certification ECU (smart key ECU assembly) may be malfunctioning. When the electrical key transmitter sub-assembly is brought into the vehicle, verification of the key ID code transmitted from the electrical key transmitter sub-assembly and the key ID code stored in the certification ECU (smart key ECU assembly) is performed. If verification cannot be performed or the codes do not match, the power switch cannot be turned on (IG) and the hybrid control system cannot be started.

When a door is unlocked and the electrical key transmitter sub-assembly is brought into the vehicle, the certification ECU (smart key ECU assembly) activates the indoor electrical key antenna assembly which transmits radio waves to detect the electrical key transmitter sub-assembly. If the electrical key transmitter sub-assembly recognizes that it is in the detection area, it responds with the key ID code. This information is received by the indoor electrical key antenna assembly and then sent to the certification ECU (smart key ECU assembly).
