SPEEDOMETER AND PILOT LAMP BOX
DESCRIPTION
This speedometer mainly consists of the stepping motor, LCD (Liquid Crystal Display) and LED (Light Emit-
ting Diode). This speedometer is light, thin and of high response compared to those currently in use
because of this composition.
The speedometer pointer is driven by the stepping motor.
The LCD indicates Odo/Trip 1/Trip 2/Clock/Fuel level and FI (DTC) respectively.
NOTE:
* If the engine stop switch is turned OFF while the ignition switch is ON, the LCD displays “CHEC”. But it is
not a malfunction.
* This condition implies that speedometer receives no signal from the ECM.
* In that case, they are restored to normal indication by turning the engine stop switch to RUN position.
LED (Light Emitting Diode)
LED is used for the illumination light and each indicator light.
LED is maintenance free. LED is less electric-power consuming and stronger to vibration resistance com-
pared to the bulb.
1Adjuster switch (Odo/Trip/Clock) 6LED (Turn signal indicator light)
2LED (Engine coolant temperature indicator light) 7LED (High-beam indicator light)
3LED (Oil pressure indicator light) 8LED (Neutral indicator light)
