9-32 ELECTRICAL SYSTEM ENGINE COOLANT TEMPERATURE METER AND INDICATOR ECT sensor inspection (7-7 to -8) • Lift and support the fuel tank. (5-3) • Disconnect the ECT sensor coupler 1.  When connecting and disconnecting the engine cool- ant temperature sensor lead wire coupler, make sure to turn OFF the ignition switch, or electronic parts may get damaged. • Connect the variable resistor A between the terminals. • Disconnect the oil pressure switch lead wire from the oil pres- sure switch. NOTE: Leave the oil pressure switch lead wire open. • Turn the ignition switch ON. • Check the LCD and LED operations when the resistance is adjusted to the specified values. E Resistance A LED B LCD C LCD D Water temperature 2.45 kΩ and over OFF “---” ------- 19 °C and below L Approx. 0.811 kΩ OFF “50” ------- Approx. 50 °C P Approx. 0.1 kΩ ON ON “120” – “139” Flicker 120 – 139 °C 0 Ω (Jumper wire) ON “HI” Flicker 140 °C and over M If either one or all indications are abnormal, replace the combi- nation meter with a new one. A NOTE: S 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.
