Operation


Passenger's side seat belt warning light

1.  When the indicator unit receives (1) the passenger's seat belt warning light on request signal from the instrument cluster while the ignition is switched ON (engine off or on), it turns on (2) the transistor.

2.  When the transistor turns on, a ground circuit with the passenger's side seat belt warning light is established and the passenger's side seat belt warning light turns on (3).

Second-row seat belt/third-row seat belt warning light

1.  When the ignition is switched ON (engine off or on), the indicator unit receives (1) the second-row seat belt/third-row seat belt warning light turning on request signal from the instrument cluster.

2.  The indicator unit turns the transistor on (2) based on the second-row seat belt/third-row seat belt warning light turning on request signal from the instrument cluster.

3.  When the transistor turns on, a ground circuit with second-row seat belt/third-row seat belt warning light is established, and the second-row seat belt/third-row seat belt warning light turns on (3).
