The IPC illuminates the CHANGE ENGINE OIL indicator when a class 2 message from the body control module (BCM) requests illumination. The BCM receives a CAN serial data message from the engine control module (ECM) when the ECM determines that the engine oil should be changed. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System Resetting in Maintenance and Lubrication.
The IPC illuminates the Low Fuel indicator when the IPC detects that the fuel level is less than a pre-determined value. The IPC receives a class 2 message indicating the fuel level percent from the BCM.
The IPC illuminates the engine oil pressure indicator when the engine control module (ECM) detects low engine oil pressure, and the signal circuit is low. The ECM sends a CAN serial data message to the BCM indicating low engine oil pressure. The BCM sends a class 2 message to the IPC requesting illumination when the engine oil pressure is low.
The IPC illuminates the REDUCED POWER indicator when a class 2 message from the body control module (BCM) requests illumination. The BCM receives a CAN serial data message from the engine control module (ECM) when the ECM determines that a certain amount of engine power has been lost.
The IPC illuminates the service vehicle soon indicator during any of the following conditions:
• | The BCM detects a security failure. The BCM sends a class 2 message to the IPC requesting illumination. |
• | The BCM detects a malfunction in the passive trunk release system. The BCM sends a class 2 message to the IPC requesting illumination. |
• | The BCM detects a failure in the traction control system. The BCM sends a class 2 message to the IPC requesting illumination. |
• | The IPC detects a mismatch between its part number and the vehicle platform configuration sent by the BCM via a class 2 message. |
• | The IPC receives a class 2 message from the BCM when certain malfunctions that are not related to the emissions system are detected. |
The BCM receives a CAN serial data message from the ECM when the ECM determines that the vehicle should be shifted to the next higher gear. The IPC illuminates the shift indicator when the BCM sends a class 2 message requesting illumination.
