| Short Description |
This signal is the Low Frequency (LF) interrogation ping from a Nissan Qashqai (Intelligent Key / Keyless Entry system). The vehicle's Body Control Module (BCM) transmits short 125 kHz ASK-modulated pulses via internal and external antennas to detect the presence of the key fob. The system operates on a trigger-based logic: a single short pulse is transmitted when any door is opened or closed. If the key fob is not detected inside the cabin after a door closes, the system switches to a continuous cycling search pattern accompanied by a dashboard warning and an interior buzzer until a timeout is reached. |
