Low Oil Indicator
The Instrument Cluster's internal circuitry will only check the
Oil Level Sensor at Ignition "ON" if Drainback Times are met (
35 minutes after Ignition "OFF" if the Engine was still cold, or
4 minutes after Ignition "OFF" if the Engine was hot. Hot is defined as running for at least
17 minutes). Drainback Timer sets at Ignition "OFF". The sensor has normally closed contacts that are open under a low oil condition. After determining a low oil condition exists, the "LOW OIL" Indicator is provided a ground for illumination. The Indicator also receives a ground for approximately
one second during the Cluster's bulb check function right after Ignition "ON".
