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)
― Heated steering wheel operation condition (with Heated steering wheel system)

Function

• The indicator unit turns the passenger seat belt warning light on/off based on the request signal sent from the instrument cluster.
• The indicator unit turns the rear seat belt indicator light on/off based on the request signal sent from the instrument cluster.
• The indicator unit turns the 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, For details on the panel light, refer to [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.


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.


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 (with 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)
― Heated steering wheel switch (with Heated steering wheel 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.If a rear seat belt is not fastened while the ignition is switched ON (engine off or on), the BCM sends (1) a rear buckle switch on signal to the instrument cluster.

2.The instrument cluster sends a rear buckle switch on signal to the indicator unit (2).

3.The indicator unit turns the rear seat belt warning light on (4) when it receives the rear buckle switch on signal from the instrument cluster.

4.When the rear seat belt is fastened, the BCM sends a rear buckle switch off signal to the instrument cluster (5).

5.The instrument cluster sends the rear buckle switch off signal to the indicator unit (6).

6.When the indicator unit receives the rear buckle switch off signal from the instrument cluster, it turns the rear seat belt indicator light on (8).

7.The BCM sends a rear buckle switch on signal to the instrument cluster (9) when the fastened rear seat belt is unfastened.

8.The instrument cluster sends a rear buckle switch on signal to the indicator unit (10).

9.When the indicator unit receives the rear buckle switch on signal from the instrument cluster, it flashes the rear seat belt warning light (11).
