The driver side indicator in the Cluster is activated by 'Driver Seat Belt Indicator Status' CAN signal and the assistant side indicator is activated by the IPM output 'Assist Seat Belt Indicator'.
Seat Belt Warning Sound:
In case of Driver side 6sec Indicator, the cluster module operates it after receiving 'Driver Seat Belt Indicator Status' from the IPM. So if the IPM sends 'Driver Seat Belt Indicator Status = blinking' over 6sec then the IPM sounds buzzer warning one more time.
Frequency: 800 Hz
Sound period: T2 = 1sec
Sound duration: T1 = 6sec
Assistant Seat Belt Indicator:
Duty: 50%
Period: T2 = 1sec
Duration: T1 = 6sec
Driver Seat Belt IND and Buzzer Sound Logic Condition

- The in-circuited magnetic buzzer sound is used for seat belt warning.
