2398896 - P30 DOORS / BOOT OPEN BUZZER NOT PRESENT WITH CAR IN MOTION

With the vehicle moving, the accidental opening of one of the doors or the boot is not indicated by the buzzer.
The instrument panel node acquires from the network the signal indicating the status of the door switches or boot and the vehicle speed. If a door or the boot are opened and the vehicle speed is over 4 km/h, an acoustic signal is emitted.
This function can be enabled/disabled via the MODE +/- keys on the controls switch panel unit. Make sure that the function has not been disabled incorrectly by the user
