id092200037400
Purpose
• The indicator unit notifies the user of the passenger seat belt status.
Function
• The indicator unit turns the passenger seat belt warning light on/off based on the request signal sent from the instrument cluster.
Seat warmer switch function (with seat warmer system)
-
• The indicator unit switches the temperature level (number of times indicator illuminated) in the order of 3, 2, 1, and OFF according to the seat warmer switch operation and sends the temperature level signal to the seat warmer unit.
• The indicator unit records the temperature level (number of times indicator illuminated) when the ignition is switched from ON (engine off or on) to off, and operates the recorded temperature level (number of indicator illumination) when the ignition is switched ON (engine off or on) again.
• If the battery power supply is disconnected, the temperature level recorded by the indicator unit is eliminated.
Construction
• The indicator unit is positioned to the center lower panel.
• The indicator unit consists of the following parts:
-
― Passenger's side seat belt warning light
― Seat warmer switch (with seat warmer system)
Operation
Passenger's side seat belt warning light
1. When the ignition is switched ON (engine off or on), the indicator unit receives (1) the passenger’s side seat belt warning light turning on request signal from the instrument cluster.
2. The indicator unit turns the transistor on (2) based on the passenger’s side seat belt warning light turning on request signal from the instrument cluster.
3. 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).
