• Engine -> Engine revolution XXXX rpm
A revolution sensor is mounted to the injection pump gear.
The gear ratio varies with the model as described below.
KX41-3's gear ratio: 46
KX61-3 and KX71-3's gear ratio: 54
KX91-3S·D, KX101-3D, KX121-3S·D, and KX161-3S·D gear ratio: 68
Calculation Method
A single rotation of the injection pump corresponds to two engine rotations.
The revolution of the engine is calculated by measuring the passing period of the number of gear tooth
specified by the timer and obtaining the revolution under the same condition for 60 seconds.
• Battery: Battery Voltage
The battery voltage is input into the meter through two diodes. Therefore, the voltage displayed is added
with 1.4 V in consideration of the potential drop caused by the diode.
• E. oil: Engine oil switch ON and OFF.
• Charge: Alternator L terminal ON and OFF.
These switches are turned ON with the engine stopped and turned OFF with the engine started while in
normal operation.
• Lever: Lever lock.
• Trave: Running in second gear.
• Start: Start position of key switch.
• Water: Water temperature voltage and water temperature ( C).
• Fuel: Fuel voltage and fuel quantity (in liters).
The quantity of fuel (in litters) displayed is a reference value.
The fuel (in liters) is displayed from data measured according to the model.
• Non anti-theft ver.: Not connected to theft prevention ECU (i.e., no communication is possible with the
theft prevention ECU).
