• Set the main switch to “ON”.
• Set the shift rod to “N”.
• Measure the voltage (DC 12V).
• Is the voltage within specification?

3. Wiring
Check the entire signaling system’s wiring.
2. Fuel level gauge
• Set the main switch to “ON”.
• Move the float up or down.
• Check that the display segments of the fuel
level gauge increase or decrease to “E” or
“F”.
TIP:
Before reading the fuel level gauge, leave
