Construction
Operation
1.When the ignition is switched ON (engine off or on), the instrument cluster receives (1) a vehicle speed signal from the PCM, and a driver's side/passenger's side buckle switch signal and occupancy sensor signal from the SAS control module via CAN communication.
2.The instrument cluster turns the transistor on (2) based on each signal.
3.When the transistor turns on, a ground circuit with the seat belt warning alarm is established and the seat belt warning alarm sounds (3).
