Self-Diagnosis Mode of Triple MeterNKS0006L
SELF-DIAGNOSIS FUNCTION
Triple meter operation can be checked with self-diagnosis mode of combination meter.
OPERATION PROCEDURE
1. While pressing the odo/trip meter switch, turn ignition switch ON.
2. Make sure that the trip meter displays “0000.0”.
3. Press the odo/trip meter switch at least 3 times (within 7 seconds after the ignition switch is turned ON).
4. All the segments on the trip computer illuminate. At this time, the triple meter is turned to self-diagnosis
mode.
NOTE:
If any of the segments is not displayed, replace triple meter.
5. Press the odo/trip meter switch. voltmeter and oil pressure
gauge should indicate as shown in the figure while pressing odo/
trip meter switch.
NOTE:
If voltmeter or oil pressure gauge is not activated, replace triple
meter.

switch is turned ON.)
NOTE:
If the meter is powered up with the ambient sensor disconnected,
ambient air temperature display will show “---” even if the sensor is
reconnected. In this case, with the sensor connected, disconnect
and reconnect the battery, then the correct temperature will be dis-
played.Refer to ATC-92, "
AMBIENT TEMPERATURE INPUT PRO-
CESS" in “ATC”.
