FUEL WARNING LAMP SENSOR CHECK




1. Turn ignition switch OFF.
2. Disconnect fuel level sensor unit harness connector B108.
3. Connect a resistor (80 Ohm) between fuel level sensor unit harness connector B108 terminals 2 (OR/B) and 4 (B).
4. Turn ignition switch ON.

The fuel warning lamp should come on.

NOTE: ECM might store DTC during this inspection. If the DTC is stored in ECM memory, erase the DTC after reconnecting the fuel level sensor unit harness connector.

DIODE CHECK




- Check continuity using an ohmmeter.
- Diode is functioning properly if test results are as shown.

NOTE: Specification may vary depending on the type of tester. Before performing this inspection, be sure to refer to the instruction manual of the tester to be used.

- Check diodes at the combination meter harness connector instead of the combination meter assembly. Refer to "Wiring Diagram - WARN -".
