DIAGNOSTIC PROCEDURE - OIL PRESSURE INDICATOR NOT OPERATING PROPERLY
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 |
NOTE:
Ensure that the engine has normal operating oil pressure before proceeding with test. Refer to the Service information for specifications. Without starting the engine, turn the ignition on.Does the Oil Pressure Indicator illuminate?Yes --> Go To 2No --> Go To 4 |
All |
| 2 | Start the engine. Does the Oil Pressure Indicator turn off? Yes --> The condition is not present at this time. Monitor DRBIII® parameters while wiggling the related wire harness. Refer to any Technical Service Bulletins (TSBs) that may apply. Visually inspect the related wiring harness and connector terminals. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 3 |
All |
| 3 | Turn the ignition off. Disconnect the Instrument Cluster harness connector. Disconnect the Oil Pressure Switch harness connector. Measure the resistance between ground and the Oil Pressure Switch circuit. Is the resistance below 5.0 ohms? Yes --> Repair the Oil Pressure Indicator circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1 . No --> Replace the Oil Pressure Switch in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 4 | Remove and inspect the Oil Pressure Warning Indicator Lamp bulb and socket. Is there a problem with the bulb or socket? Yes --> Replace the Indicator bulb or socket as necessary in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 5 |
All |
| 5 | Turn the ignition off. Disconnect the Instrument Cluster harness connector. Disconnect the Oil Pressure Switch harness connector. Turn the ignition on. Measure the voltage between the Oil Pressure Indicator circuit and ground. Is there any voltage present? Yes --> Repair the Oil Pressure Indicator circuit for a short to voltage. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 6 |
All |
| 6 | Turn the ignition off. Disconnect the Instrument Cluster harness connector. Turn the ignition on. Using a 12-volt test light connected to ground, check the Fused Ignition Switch Output circuit. Does the test light illuminate brightly? Yes --> Go To 7 No --> Repair the Fused Ignition Switch Output circuit for an open or high resistance circuit. If the fuse is open make sure to check for a short to ground and repair as necessary. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 7 | Turn the ignition off. Disconnect the Oil Pressure Switch harness connector. Turn the ignition on. Using a 12-volt test light connected to ground, check the Oil Pressure Indicator circuit. Does the test light illuminate brightly? Yes --> Go To 8 No --> Repair the Oil Pressure Indicator circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 8 | Turn the ignition off. Disconnect the Oil Pressure Switch harness connector. Measure the resistance between the Oil Pressure Switch terminal pin and ground.
NOTE:
With the engine not running the Oil Pressure Switch should be closed to ground. Does the Oil Pressure Switch terminal pin have continuity to ground? Yes --> Replace the Instrument Cluster in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . No --> Replace the Oil Pressure Switch in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . |
