Backup Communication Function
When key authentication between the remote and the body control module is not possible because of a system abnormality or a drop of the battery voltage of the remote, the immobilizer function can be canceled by pressing the engine start/stop switch button once and bringing the remote close to the engine start/stop switch while the engine start/stop switch indicator is flashing. This causes the immobilizer signal to be sent to the body control module via the LF antenna of the engine start/stop switch.
