Wait To Start Light: Description and Operation
GLOW PLUG INDICATOR LAMP (GPIL)
Glow Plug Indicator
The 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 controller area network (CAN). The on-time normally varies
between 1 and 10 seconds and is independent of the 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.
