Purpose
Outputs a request signal and specifies the remote transmitter location.
Function
The keyless antenna outputs request signals to the inside and outside of the vehicle based on the signals from the LF control unit.
Construction, Operation
The antennas for request signal output form the request signal output range at 5 locations.

Request signal output range
The keyless antennas for the vehicle exterior (driver-side, passenger-side, rear) form the request signal output area in the range of an approx. 80 cm {31 in}
radius from each location and communicate with the advanced key.
The keyless antennas for the vehicle interior (front, rear) form the output range inside the vehicle.

Fail-safe
Function not equipped.

Keyless Antenna [Keyless Entry System]Air Fuel Ratio (A/F) Sensor Heater Control [Skyactiv G 2.0]
Outline
Based on the control of the A/F sensor heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.
