INSPECTION

LED (LIGHT EMITTING DIODE)
• Check that the LEDs (Oil pressure indicator light and meter
panel illumination) immediately light up when the ignition
switch is turned to ON.
• Check that other LEDs (Neutral indicator light, High-beam
indicator light and Turn signal indicator lights) light up/go off
by operating each switch.
• If abnormal condition is found, replace the combination meter
unit with a new one after checking its wire harness/coupler.
FUEL LEVEL INDICATOR
To test the fuel level indicator, perform the following test.
Test 1
This test will determine if the fuel level indicator is operating.
• Remove the fuel tank mounting bolts.
• Disconnect the fuel level gauge lead wire coupler 1.
• Connect a jumper wire A between the Y/B and B/W lead
wires from the wire harness.
• Turn the ignition switch to ON.
• Check if the fuel level indicator (LCD) indicates full position.
NOTE:
It takes approx. 30 seconds that the fuel level indicator indicates
the detected fuel level.
Test 2
This test will determine the accuracy of the fuel level indicator in
the empty and full positions.
• Connect a 180 Ω resister B between the Y/B and B/W lead
wires from the wire harness.
• The fuel level indicator is operating correctly if the LCD bars
decrease to empty when the ignition switch is turned to ON.
