Demonstration function

Note
•  The demonstration function force-displays the active driving display without the engine being started, such as on an indoor exhibition vehicle, so that customers can verify the display status.
•  Because the demonstration function launches the active driving display with the ignition switched ON (engine off), take measures to prevent battery discharge such as connecting an external power supply to the vehicle.
•  The demonstration function launches the active driving display with the ignition switched ON (engine off) to display the vehicle information in the display.
Demonstration function on/off setting procedure (digital speedometer type (type B))
1.  With the tripmeter switch in the instrument cluster pressed, switch the ignition as follows.
•  Ignition off→Ignition ON (engine off)→Ignition off→Ignition ON (engine off)
2.  Release the tripmeter switch when [test] is displayed in the instrument cluster.
Note
•  When the tripmeter switch is released with [test] displayed in the instrument cluster, the entire instrument cluster is turned on.
3.  Press the tripmeter switch and display [06 on] or [06 off] in the instrument cluster.
•  Select [06 on] to turn on the demonstration function.
•  Select [06 off] to turn off the demonstration function.
4.  Switch the ignition off.
Note
•  If the ignition is switched off with [06 on] displayed in the instrument cluster (demonstration function on), the demonstration function will operate the next time the ignition is switched ON (engine off).
•  If the following is performed with the demonstration function on, the demonstration function turns off.
―  The battery power is interrupted or the ROOM fuse is removed.
―  The vehicle is driven at 20 km/h {12 mph} or more.
Demonstration function on setting procedure (digital speedometer type (type A))
1.  Verify that the all doors are closed.
2.  After switching the ignition ON (engine off), switch the light switch within 5 s as follows.
•  OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF
3.  Switch the light switch (dimmer switch) within 5 s after Step 2 as follows.
•  OFF→Headlight HI ON→OFF→Headlight HI ON→OFF→Headlight HI ON→OFF
4.  Switch the light switch as follows to turn the demonstration function on.
•  OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF→TNS (parking lights)→OFF→TNS (parking lights)
Note
•  After Step 4, the combiner closes when the demonstration function turns on.
5.  Switch the ignition off.
Note
•  If the ignition is switched off with the demonstration function turned on, the demonstration function will operate the next time the ignition is switched ON (engine off).
•  If the following is performed with the demonstration function on, the demonstration function turns off.
―  The battery power is interrupted or the ROOM fuse is removed.
―  The vehicle is driven at 20 km/h {12 mph} or more.
Demonstration function off setting procedure (digital speedometer type (type A))

•  After Step 3, the combiner displays “Demonstration Mode OFF” when the demonstration function turns off.
4.  Switch the ignition off.


Construction

•  The active driving display is assembled to the instrument cluster.
•  The active driving display consists of a display device which produces the display content and emits the content over a light beam, a reflector which reflects the light beam emitted from the display device, a combiner which reflects the light beam from the reflection and displays the screen, a motor which opens/closes the combiner, and a photo sensor which detects the brightness surrounding the display device.
•  The combiner is a processed, clear panel for reflecting the light beam from the display device.
•  The combiner opens at the top of the meter hood and displays vehicle information in the forward visual range of the driver. As a result, the time in which the driver's line of vision changes from the view at the front of the vehicle to the view of the vehicle information reflected in the combiner has been shortened.
•  By using a concave shaped combiner, the image reflected in the combiner is positioned virtually 1.5 m {4.9 ft} forward of the eye point. As a result, the eye point adjustment time in which the driver's line of vision changes from the view at the front of the vehicle to the view of the vehicle information reflected in the combiner has been reduced.

Operation

1.  When the ignition is switched ON (engine on), the instrument cluster opens the combiner based on the following CAN signals. (1)
―  ROOM fuse status signal from BCM
―  Combiner target angle signal from connectivity master unit (CMU)
Note
•  When the position memory switch is operated, the active driving display adjusts the angle of the combiner based on the CAN signal (1) from the position memory control module.
2.  When the combiner opens, the instrument cluster displays the opening screen (vehicle name) for approx. 2 s. In addition, it sends an active driving display execute signal and combiner current position signal (2) to the connectivity master unit (CMU).
Note
•  The connectivity master unit (CMU) records the current position of the combiner based on the combiner current position signal from the instrument cluster. When the ignition is switched from off to ON (engine on), it sends the target angle signal based on the recorded current position.
•  The combiner current position recorded by the connectivity master unit (CMU) is not cleared even if the battery power is disconnected.
•  If the connectivity master unit (CMU) has not recorded the combiner current position, it sends the target angle signal of the initial value.
3.  After the opening screen is turned off, the instrument cluster displays the current vehicle speed based on the vehicle speed signal (3) from the PCM, and displays the warning or other screens based on request signals (4) from related modules.

Fail-safe

•  The instrument cluster turns off the active driving display images under the following conditions and stops the display at the current position.
―  Error signal from connectivity master unit (CMU) is received, and CMU malfunction is determined (digital speedometer type (type A))
―  Communication with connectivity master unit (CMU) is interrupted (digital speedometer type (type A))
―  Motor malfunction for combiner operation is detected
