9000 CSE L4-2290cc 2.3L DOHC Turbo EFI (1995)
The outside temperature sensor consists of an NTC resistor across which the resistance varies with temperature. The control module registers the outside
temperature by measuring the thermistor resistance.
If the outside temperature drops from a higher temperature down to 3° C (37° F) or rises from a lower temperature to -3° C (26° F), the outside
temperature will automatically be shown on the display irrespective of which display the Electronic Display Unit (EDU) control module is set to.
This display remains until the outside temperature leaves the range of -6° C (43° F) to 6° C (21° F) or until another function is selected by pressing the
INFO button.
The EDU control module then sends a temperature signal to the Automatic Climate Control (ACC) control module.
Battery Positive Voltage Indication
To show the battery positive voltage on the display, the Electronic Display Unit (EDU) control module registers the voltage from the ignition switch +15
lead at 1 second intervals.
The EDU control module measuring range is 7.5 to 16 V.
When the engine is started, the battery positive voltage is shown on the display. The value displayed is the lowest voltage measured while the starter
motor is turning the engine.
When the car has travelled 10 to 15 meters, the display reverts to the previously selected mode.
