Circuit/System Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The driver efficiency gauge shows when the vehicle is operating at a fuel efficient point. There are several zones on the gauge indicating different levels of efficiency. The gauge shall indicate fuel efficiency when the engine is running and will be set at the minimum scale position when the ignition transitions to a mode other than when the engine is running. The gauge will set at its half scale position when there is a loss of communication. The engine control module (ECM) provides information to the instrument panel cluster (IPC) for the driver efficiency gauge via the serial data circuit.
