The instrument panel cluster (IPC) illuminates the CHANGE ENGINE OIL SOON message when the engine control module (ECM) determines that the engine oil should be changed. The IPC receives a class 2 message from the ECM requesting illumination. Once the oil is changed, perform the engine oil monitor reset procedure in order to clear the Change Engine Oil indicator.
