CHECK OIL LEVEL Message
This information applies to 1999-2007 Chevrolet Silverado Classic and GMC Sierra Classic, 2002-06 Cadillac Escalade, Chevrolet Avalanche, Suburban, Tahoe, and GMC Yukon and Yukon Denali.
The CHECK OIL LEVEL message may display after a repair if the key is left on when doing an oil change, or after topping off the engine oil due to a low oil condition.
When using the Tech 2 to view the Engine Oil Level Switch data parameter, it will show OK, but the CHECK OIL LEVEL message will still be displayed on the DIC.
These conditions could result if the engine coolant temperature criteria have not been met to reset the CHECK OIL LEVEL. The system must see a 50° F (10° C) drop in engine coolant temperature to recheck the engine oil level.
To correct this concern, allow the engine to run until operating temperature is reached. Then shut the engine off and allow the engine to cool down for 1 to 2 hours with the key in the off position.
On the next key cycle, if the engine oil level is OK, the DIC message will remain off.
