Auto Stop/Start Warning Indicator
On vehicles with auto stop/start system, an auto stop/start warning indicator is located in the Instrument Cluster (IC). The warning indicator illuminates green when the engine stops during a stop/start cycle, then expire when the engine restarts. The warning indicator illuminates white when the auto stop/start system is disabled. To illuminate the auto stop/start warning indicator, the Powertrain Control Module (PCM) sends a signal to the Body Control Module/Gateway Module (BCM/GWM) assembly via FlexRay bus. The BCM/GWM assembly transmits the request signal to the IC via the High Speed (HS) Controller Area Network (CAN) chassis systems bus.
