Checking the fuel meter/fuel level warning light

This model is equipped with a self-diagnosis device for the fuel level detection circuit.

1. Check:

Fuel meter/fuel level warning light "1" (Turn the main switch to "ON".) Warning light comes on for a few seconds, then goes off → Warning light is OK.

Warning light does not come on → Replace the meter assembly.

Warning light flashes eight times, then goes off for 3 seconds in a repeated cycle (malfunction detected in fuel sender) → Replace the fuel pump assembly.

Checking the oil level warning light

This model is equipped with a self-diagnosis device for the oil level detection circuit.

1. Check:

• Oil level warning light "1" (Turn the main switch to "ON".) Warning light comes on for a few seconds, then goes off → Warning light is OK.

  Warning light does not come on → Replace the meter assembly.

  Warning light flashes ten times, then goes off for 2.5 seconds in a repeated cycle (malfunction detected in oil level switch) → Replace the oil level switch.
