INDICATOR UNIT

id092200037400


Purpose

•  The indicator unit notifies the user of the following conditions.
―  Passenger's side seat belt fastened condition
―  Second-row seat belt/third-row seat belt fastened condition (Australian specs.)
―  Seat warmer operation condition (With seat warmer system)
―  Heated steering wheel operation condition (With heated steering wheel system)

Functions

•  The indicator unit turns the passenger and second-row/third-row 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 indicators turned on) 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 indicators turned on) when the ignition is switched from ON (engine off or on) to off, and operates at the recorded temperature level (number of indicators turned on) 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.


Heated steering wheel switch function (With heated steering wheel system)

•  The indicator unit sends a heated steering wheel on/off signal according to the heated steering wheel switch operation.


Structure/Construction

•  The indicator unit is positioned in the front console.
•  The indicator unit consists of the following parts.
―  Passenger's side seat belt warning light
―  Second-row seat belt/third-row seat belt warning light (Australian specs.)
―  Seat warmer switch (With seat warmer system)
―  Heated steering wheel switch (With heated steering wheel system)

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 (Australian specs.)

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).
