Reduced Engine Power
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) illuminates the REDUCED POWER indicator when a class 2 message from the body control module (BCM) requests illumination. The BCM receives a controlled area network (CAN) serial data message from the engine control module (ECM) when the ECM determines that a certain amount of engine power has been lost.
