UP-SHIFT INDICATOR : System Description

INFOID:0000000009189331

• The combination meter receives the engine speed signal from ECM and the shift position signal (manual

mode range) from TCM via CAN communication, and illuminates/turns off/blinks the up-shift indicator.

• The engine speed at which the up-shift indicator is illuminated/turned off/blinked can be set with the setting

function of information display.

- OFF: All of the up-shift indicators do not illuminate.
- 3,000 to 6,300 rpm: Engine speed can be set at which the up-shift indicator (green) is illuminated. 
- AUTO: Up-shift indicator (green) does not illuminate. The up-shift indicator (yellow) and up-shift indicator

(red) is turned on/off according to the set value.

UP-SHIFT INDICATOR (GREEN)

• Using the setting function of information display, the up-shift warning speed can be set.
• The up-shift indicator (green) is illuminated/turned off/blinked according to the engine speed.
- OFF: If the actual engine speed is lower than the arbitrarily set engine speed, which is 3,000 to 6,300 rpm

set by the setting function of information display, by 500 rpm or more, the up-shift warning lamp is turned
OFF. 
Also, while the up-shift indicator (green) is blinking or illuminated, if the actual engine speed becomes lower
than the arbitrarily set engine speed by 600 rpm or more, the up-shift warning lamp is turned OFF.

- Blink: If the actual engine speed is lower than the arbitrarily set engine speed by 500 rpm or more, the up-

shift indicator (green) is blinked. 

- ON: When the actual engine speed exceeds the arbitrarily set engine speed, the up-shift indicator (green) is

illuminated.
Also, while the up-shift indicator (green) is blinking or illuminated, if the actual engine speed becomes lower
than the arbitrarily set engine speed by 100 rpm or more, the up-shift indicator is blinked. 

UP-SHIFT INDICATOR (YELLOW)

The up-shift indicator (yellow) is turned ON/OFF according to the engine speed.
• OFF: When the engine speed is less than 6,300 rpm, the up-shift indicator (yellow) does not illuminate.

Also, while the up-shift indicator (yellow) is illuminated, when the engine speed becomes 6,200 rpm or lower,
the up-shift indicator (yellow) is turned OFF.

• ON: When the engine speed becomes 6,300 rpm or more, the up-shift indicator (yellow) is illuminated.

UP-SHIFT INDICATOR (RED)

The up-shift indicator (red) is turned ON/OFF according to the engine speed.
• OFF: When the engine speed is less than 6,800 rpm, the up-shift indicator (red) does not illuminate.

Washer level switch

Transmits the washer level switch signal to the combination meter.

Ambient sensor

Detects the ambient air temperature, and transmits the ambient sensor signal to the combina-
tion meter.

Also, while the up-shift indicator (red) is illuminated, when the engine speed becomes 6,700 rpm or lower,
the up-shift indicator (red) is turned OFF.

• ON: When the engine speed becomes 6,800 rpm or more, the up-shift indicator (red) is illuminated.

DIAGNOSIS SYSTEM (METER)

DIAGNOSIS SYSTEM (METER)

Diagnosis Description

INFOID:0000000009189334

SELF-DIAGNOSIS MODE

Using the self-diagnosis mode function, the combination meter can check the drive circuit of each meter
(speedometer, tachometer, engine coolant temperature gauge, and fuel gauge), dot matrix (odo/trip meter,
information display), and the LCD function of segment (shift position indicator).

OPERATION PROCEDURE

1.

Turn the ignition switch ON, and switch the tripmeter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” is reset to “0000.0”.
(The same way for “trip B”.)

2.

Turn the ignition switch OFF.

3.

While pressing the trip A/B reset switch (1), turn the ignition
switch ON again.

4.

Check that the tripmeter displays “0000.0”. 

5.

Press the trip A/B reset switch at least 3 times (within 7 seconds
after the ignition switch is turned ON).

6.

The combination meter self-diagnosis mode starts.
• On the information display (1), the dots of the dot matrix blink

alternately.

• Pointers of speedometer, tachometer, and engine coolant tem-

perature gauge return to zero, and all of the segments of shift
position indicator illuminate.

NOTE:
• If the self diagnosis mode of combination meter does not start, check the combination meter power sup-

ply and ground circuit. When everything is normal, replace the combination meter.

• If any section of the dot matrix on information display or of the segment in shift position indicator does

not illuminate, replace the combination meter.
