Wait To Start Light: Description and Operation

GLOW PLUG INDICATOR LAMP


Glow Plug Indicator:






The glow plug indicator lamp (GPIL) is located in the instrument cluster and is used to inform the operator when the engine is ready to be started. The indicator is controlled by the instrument cluster based on an electronic command signal from the PCM through the standard corporate protocol (SCP) communications network. On-time normally varies between 1 and 10 seconds and is independent of glow plug relay on-time. As a prove out, the indicator is commanded on at every key cycle even though the glow plug system may not be required.
