Oil Level Warning

The DIC CHECK OIL LEVEL message is displayed to alert the driver of a low oil level condition. The low oil sensing circuit consists of an oil level module and low oil level sensor This system is active only at initial engine starting and not while the engine is running. The oil level is measured if the engine has been off long enough for top engine oil to have returned to the oil pan.

The oil level module receives battery power at all times to retain memory of engine on and off times. If the ignition on input as been at 0 volts for at least 8 minutes, the oil level module activates the low oil level sensor. If the sensor returns a signal indicating a low oil condition, the DIC displays CHECK OIL LEVEL 15 to 25 seconds after the ignition switch is turned to "RUN." If the ignition switch is turned off for less than 20 seconds, the oil level module remembers and sends the previous oil level status to the Driver Information Center (DIC) and ignores the present oil status. If the ignition switch has been "OFF" for more then 20 seconds, but less than 8 minutes, the oil level module ignores the low oil sensor.
