Alarm Phase
WARNING: This page is about a different car, the 2015 Infiniti Q70. However, it is still accessible from the selected car via links, so may be relevant.
BCM transmits "Theft Warning Horn Request" signal and "High Beam Request" signal intermittently to IPDM E/R via CAN communication. In this phase, horns and headlamps are activated intermittently for approximately 50 seconds to warn that the vehicle is accessed by unauthorized means. ON/OFF timings of horns and headlamps are synchronized.
To cancel the ALARM operation, refer to the switching condition of No. 12 in OPERATION FLOW .
NOTE:
If a battery terminal is disconnected during the ALARM phase, theft warning alarm stops. But when the battery terminal is reconnected, theft warning alarm is activated again.
