INDICATOR UNIT

id092200037400


Purpose

•  The indicator unit notifies the user of the following conditions.
―  Passenger seat belt status
―  Rear seat belt status (With rear seat belt reminder system)
―  Passenger air bag deactivation (PAD) switch status (With passenger air bag deactivation (PAD) system)
―  Seat warmer operation status (With seat warmer system)

Function

•  The indicator unit turns the passenger and rear seat belt warning light on/off based on the request signal sent from the instrument cluster.
•  The indicator unit turns the seat warmer switch on/off based on the panel light signal sent from the instrument cluster. For details on the panel light, refer to [PANEL LIGHT]. (With seat warmer system) (See PANEL LIGHT.)

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
―  Rear seat belt warning light
―  Passenger air bag deactivation (PAD) lettering illumination (With passenger air bag deactivation (PAD) system)
―  Passenger air bag deactivation (PAD) OFF/ON indicator light (With passenger air bag deactivation (PAD) system)
―  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).

Rear seat belt warning light (With rear seat belt reminder system)

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

2.  The indicator unit turns the transistor on (2) based on the rear seat belt warning light turning on request signal from the instrument cluster.

3.  When the transistor turns on, a ground circuit with rear seat belt warning light is established, and the rear seat belt warning light turns on (3).
