Indicators

INDICATOR/WARNING MESSAGE DESCRIPTION AND OPERATION





























INDICATORS

CHANGE ENGINE OIL
The instrument panel cluster (IPC) illuminates the CHANGE ENGINE OIL indicator in the message center when the powertrain control module (PCM) determines that the engine oil should be changed. The IPC receives a class 2 message from the PCM indicating the remaining oil life percent. Once the oil is changed, perform the engine oil monitor reset procedure in order to clear the CHANGE ENGINE OIL indicator. Refer to GM Oil Life System - Resetting in Maintenance and Lubrication.

CHECK GAS CAP
The instrument panel cluster (IPC) illuminates the CHECK GAS CAP indicator in the message center when the gas cap is not tightened properly. The IPC receives a class 2 message from the engine control module (ECM) or the powertrain control module (PCM) indicating fuel tank pressure.

LOW FUEL
The instrument panel cluster (IPC) illuminates the LOW FUEL indicator in the message center when the fuel level is less than 11 percent (1/16) of a tank. The IPC receives a class 2 message from the engine control module (ECM) or the powertrain control module (PCM) indicating fuel level percent.

LOW ENG OIL LEVEL
The instrument panel cluster (IPC) illuminates the LOW ENG OIL LEVEL indicator in the message center when the engine control module (ECM)/powertrain control module (PCM) detects a low engine oil condition, the signal circuit is high. The IPC receives a class 2 message from the ECM/PCM requesting illumination.

LOW OIL PRESSURE
The instrument panel cluster (IPC) illuminates the LOW OIL PRESSURE indicator in the message center when the engine control module (ECM)/powertrain control module (PCM) detects a low oil condition, the signal circuit is low. The IPC receives a class 2 message from the ECM/PCM requesting illumination.

SERVICE VEHICLE SOON
The instrument panel cluster (IPC) illuminates the SERVICE VEHICLE SOON indicator in the message center when the engine control module (ECM)/powertrain control module (PCM) or the body control module (BCM) detects certain non-emissions related malfunctions. The IPC receives a class 2 message from the ECM/PCM or from the BCM requesting illumination.
