COMBINATION METER
DESCRIPTION
This combination meter mainly consists of the stepping motor, LCD (Liquid Crystal Display) and LED (Light Emitting Diode). This combination meter is light, thin and of high response compared to those currently in use because of this composition.
The rpm pointer is driven by the stepping motor.
The LCDs indicate Speed, Odo/Trip1/Trip2/Clock/Fuel reserve’s trip and Engine coolant temp./FI (DTC) respectively.
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 compared to the bulb.
Engine RPM indicator light
This speedometer is equipped the engine RPM indicator light. The engine RPM indicator light is adjustable from 7 000 – 16 000 r/min. (from 7 000 r/min to 10 000 r/min, every 500 r/min and 10 000 r/min to 16 000 r/min, every 250 r/min initial setting: 13 000 r/min)

INSPECTION
LED (LIGHT EMITTING DIODE)
Check that the LED lights [FI light, Fuel level indicator light, Engine RPM indicator light and immobilizer indicator light (For E-02, 19, 24)] immediately after turning the ignition switch on. Also, other LED lights (Neutral indicator light, High-beam indicator light and Turn signal indicator light) can be checked by depending on each switch position.
If the LED fails in operation, replace the combination meter unit with a new one after checking its wire harness/coupler.
STEPPING MOTOR
Check that the pointer calibrates itself immediately after turning the ignition switch on and stops at zero point.
If abnormal condition is found, replace the combination meter unit with a new one after checking its wire harness/coupler.

The pointer may not return to theAproper position even turning the ignition switch on under low temperature
condition. In that case, you can reset the pointer to the proper position by following the instruction below:
1)With the adjuster switch A pressed, turn the ignition switch on.
2)Release the adjuster switch A, 3 to 5 seconds after turning the ignition switch on.
3)Press the adjuster switch A twice (within 1 second). →Reset
* Complete the operation within 10 seconds after the ignition switch has been turned on.

NOTE:
If the engine stop switch is turned OFF or side-stand/ignition inter-lock system is not working while the ignition switch is ON, the LCD displays “CHEC”. But it is not a malfunction.
This condition implies that combination meter receives no signal from the ECM.
In that case, they are restored to normal indication by turning the engine stop switch to RUN position.

OIL PRESSURE INDICATOR
NOTE:
Before inspecting the oil pressure switch, check if the engine oil level is correct. ( 2-12)
•Remove the left under cowling. ( 8-5)
•Disconnect the oil pressure switch lead wire from the oil pressure switch.
•Turn the ignition switch ON.
•Check if the oil pressure indicator A will light and LCD B will flicker, when grounding the lead wire.
If any indications are abnormal, replace the combination meter with a new one after checking connection of couplers.
