Reduced Engine Power
WARNING: This page is about a different car, the 2007 Suzuki XL7. 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 serial data message from the body control module (BCM) requests illumination. The BCM receives a controller area network (CAN) serial data message from the powertrain control module (PCM) when the PCM determines that a certain amount of engine power has been lost.
