Warning Lamps

FUEL WARNING LAMP SENSOR CHECK




1. Turn ignition switch OFF.
2. Disconnect fuel level sensor unit harness connector B108.
3. Connect a resistor (80 Ohms) between fuel level sensor unit harness connector terminals 2 (OR/B) and 4 (B).
4. Turn ignition switch ON.
The fuel warning lamp should come on.

NOTE: ECM might store the 1st tip DTC P0180 during this inspection. If the DTC is stored in ECM memory, erase the DTC after reconnecting the fuel level sensor unit harness connector.
Refer to "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION".




OIL PRESSURE SWITCH CHECK
Check the continuity between oil pressure switch terminal 1 and body ground.




DIODE CHECK
- Check continuity using an ohmmeter.
- Diode is functioning properly if test results are as shown in the figure.
- Check diodes at the combination meter harness connector instead of the combination meter assembly. Refer to "Wiring Diagrams-WARN".

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