●Check the Sensor and Senor Connection Harness.
●Check the Illumination Power Signal Wire of the Power Supply Harness.
●Calibration of the sensor is required when Pressure Meter does not display
“0” at atmospheric pressure. (See Below)
【
Method
】
Turn Ignition [ON] – without turning the engine on. Wait for at least 10
seconds. (during this time, the unit will calibrate the value to “0”). When
sensor calibration is completed,“
ＣＡＬ”
will appear on the digital meter
display for at least 1 second. If engine is turned on before 10 seconds, then
the sensor calibration procedure will need to be repeated.
Check each Sensor harness and Sensor again.
Main Display Unit or Sensor Unit may have
operation failure, please consult with your dealer of
purchase.
Temperature displays ”
－－．－”
when the temperature is at freezing point (below
０℃)
or when the temperature sensor is disconnected or not securely connected.
Pressure displays ”
－.－－”
when the pressure sensor is disconnected or not securely
connected.
Check the Sensor Harness connections.
The analog needle of the meter
display does not move or is moving
abnormally.
Display brightness does not change
when parking lights are turned ON.
If Pressure Meter displays a value
that is not “0” at atmospheric
pressure (engine turned off).

● Turn Ignition to the [ON] position, check to make sure the meter display
needle sweeps up and back down.
● Turn Ignition to the [ON] position, check to make sure the LED indicators
change color.
● Turn Ignition to the [ON] position, check to make sure the Digital Meter
numerical values are displayed in 1,2,…order sequence, and back to zero.
● Make sure the pressure sensor is calibrated.
※ Refer to [Frequently Asked Question] for calibration method.
● Please check for any unusual noise or odor coming from the unit.
● Once the engine is running, be sure to check for water or oil leaks.
● Once the engine is running, be sure to check that there is no interference
for each individual part.

● Meter parameters are displayed in a real-time analog needle display
(As shown in Diagram: A-1 & A-2). When the measured value
exceeds the numerical value displayed, the analog needle will
transition into an over-scale display (Temperature only). During the
over-scale display, the analog needle will illuminate brighter to
indicate the measured value (As shown in Diagram: A-3). However,
when only the indicator needle line is displayed as shown in
{Diagram: A-1}, the values will change.
Temperature 1・・・Normal Scale ３０℃～１３０℃
Over-Scale 1３０℃～１９０℃
Temperature 2・・・Normal Scale ５０℃～１５０℃
Over-Scale １５０℃～１９０℃
