INDICATORS

CHANGE ENGINE OIL
The instrument panel cluster (IPC) illuminates the CHANGE ENGINE OIL message in the message center when the powertrain control module (PCM) determines that the engine oil needs to changed. The PCM sends a class 2 message to the IPC requesting illumination. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System - Resetting in Maintenance and Lubrication.

LOW ENG OIL LEVEL
The instrument panel cluster (IPC) illuminates the LOW ENG OIL LEVEL message in the message center if the powertrain control module (PCM) detects low engine oil level, and the signal circuit is high. The PCM only monitors the signal circuit of the engine oil level switch for a brief period when the key moves from ON to START. The IPC receives a class 2 message requesting illumination from the PCM.

LOW FUEL
The instrument panel cluster (IPC) illuminates the LOW FUEL message in the message center when the powertrain control module (PCM) determines that the fuel level is less than 12 percent. The IPC receives a class 2 message indicating the fuel level from the PCM.

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

OVER SPEED
The instrument panel cluster (IPC) illuminates the OVER SPEED message in the message center when the powertrain control module (PCM) detects that the vehicle speed is greater than 120 km/h (74.5 mph).
