Infiniti QX56 (Z62). Manual — part 942
MWI-22
< SYSTEM DESCRIPTION >
SYSTEM
The combination meter measures and displays travel time (ignition switch ON time).
Travel Distance
The combination meter calculates mileage, based on the following signals and displays the mileage on the
information display.
Ambient Temperature
• The combination meter corrects an indicated temperature, based on various signals.
• The combination meter calculates ambient air temperature based on the following signals, and the calcu-
lated value is displayed on the information display.
Correction Process (Temperature indicated soon after the ignition switch ON)
• A temperature indicated soon after the ignition switch is turned ON depends on the time from the ignition
switch OFF to ON and a temperature detected by the ambient sensor.
When any condition described below is met, an ambient sensor-detected temperature is indicated.
- Time from the ignition switch OFF to ON
≥
Predetermined time
- Sensor-detected temperature < Temperature at the last ignition switch OFF
Correction Process (Temperature at the Ignition switch ON)
• A temperature indicated when the ignition switch is ON depends on a vehicle speed, an ambient sensor-
detected temperature, and traveling time.
The temperature on the information display is corrected to an ambient sensor-detected temperature when the following condition
is met.
- Ambient sensor-detected temperature < Temperature on the information display
A temperature on the information display is not updated when the following condition is met.
- Ambient sensor-detected temperature
≥
Temperature on the information display
- Vehicle speed
≤
20 km/h (12 MPH)
A temperature on the information display slowly rises to an ambient sensor-detected temperature when the following condition is
met.
- Ambient sensor-detected temperature
≥
Temperature on the information display
- Vehicle speed
≥
20 km/h (12 MPH)
A temperature on the information display rapidly rises to an ambient sensor-detected temperature when the following condition
is met.
- Ambient sensor-detected temperature
≥
Temperature on the information display
- Vehicle speed
≥
20 km/h (12 MPH)
- When driving more than set time
A/C auto amp. connection recognition
• The combination meter judges the A/C auto amp. connection/disconnection, based on an A/C auto amp.
connection recognition signal to judge the presence/absence of the ambient sensor power output.
NOTE:
• After an ignition switch is turned ON, “–––” is displayed until after a 2.5 seconds.

• The ambient sensor input value that is displayed on “Data Monitor” of CONSULT-III is the value before the
correction. It may not match the indicated temperature on the information display.
• After removal and installation of the battery and combination meter, an ambient sensor-detected tempera-
ture is indicated on the information display.
• Depending on engine heat or heat on the road surfaces, an ambient temperature may be indicated higher
than actual one.
INTERRUPT INDICATION
• The combination meter displays an interrupt regarding a warning, alert, and maintenance on the information
display, based on signals received from each unit and switch.
• When conditions are satisfied, the normal screen switches to a warning screen to display an interrupt.
Door Open Warning
• When all the following operating conditions are satisfied, the combination meter displays a door open warn-
ing on the information display by an interrupt.
• The combination meter judges showing/hiding of “door open warning”, according to the signals below:
Parking Brake Release Warning
• When all the following operating conditions are satisfied, the combination meter displays a parking brake
release warning on the information display by an interrupt.
• The combination meter judges showing/hiding of “parking brake release warning”, according to the signals
below:
Low Fuel Warning
• When all the following operating conditions are satisfied, the combination meter displays a low fuel warning
on the information display by an interrupt.
