Check Engine Oil Pressure

The IPC illuminates the engine oil pressure indicator and activates an audible warning when the following occurs:
^ The Powertrain Control Module (PCM) detects that the engine oil pressure is outside the normal operating range. The IPC receives a class 2 message from the PCM requesting illumination.
^ The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
