Meter, Gauge, Indicator Unit
Meter System Inspection
Check 2-1: Tachometer Brightness Sensor Inspection
NOTE
○
This meter unit has the automatically tachometer bright-
ness function by the sensor in addition to the manual
brightness setting.
•
Push the upper and lower buttons, and hold them in until
the all tachometer segments go on.
•
Check if the tachometer brightness [A] is changed by shin-
ing a light on the sensor [B] with the penlight.
•
Push the upper and lower buttons, and hold them to finish
the setting mode.
If the meter does not work, replace the meter unit.
Check 2-2: Water Temperature Inspection
•
Disconnect the water temperature sensor connector [A]
(see Water Temperature Sensor Removal/Installation in
the Fuel System (DFI) chapter).
•
Connect the variable rheostat [B] to the W/BL lead [C] and
W/R lead [D] terminals.

•
Turn the ignition switch on.
•
Read the temperature in the display.
The display range is 40 ∼ 119°C (104 ∼ 247°F).
If the temperature is out of the range, check the wiring
(see Meter Circuit).
If the wiring is good, replace the meter unit.
Check 2-3: Battery Warning Indicator Inspection
•
When the battery condition is low voltage (10.8 ∼ 11.2 V or
less) or high voltage (15.5 ∼ 16.5 V or more), the battery
warning indicator [A] and red warning indicator (LED) [B]
go on.
If the battery warning indicator and red warning indicator
(LED) go on, inspect the charging voltage (see Charging
Voltage Inspection).
If the charging voltage is good, replace the meter unit.
