Low Oil Indicator

The Power Control Module (PCM) via the class II data line controls the LOW OIL level indicator. The PCM samples the oil level 1 per ignition cycle, only at power-up. Test for low oil level at the start-up when one of the following conditions present:

^ If the engine coolant temperature was between 15°C (59°F) and 90°C (194°F) at the last key OFF, ensure that the engine coolant temperature at key ON is at least 12°C (22°F) cooler than the engine coolant temperature at the last key OFF.
^ If the engine coolant temperature was higher than 90°C (194°F) at the last key OFF, ensure that the time between the last key OFF and the present key ON is sufficient in order to allow the oil to drain back to the sump. The PCM will remain powered up for 10 seconds in order to ensure that the oil has drained back to the sump. If the key is turned back to ON while the PCM is still powered up, the oil level will not be tested.
^ The LOW OIL level indicator lights under the following conditions:
- When the PCM determines that a low oil level condition exists.
- During a period of time when the ignition is first turned ON for a bulb test.
