Wait To Start Light: Description and Operation

ENGINE CONTROL COMPONENTS

Glow Plug Indicator
The glow plug indicator is located in the instrument panel cluster and informs the operator when the engine is ready to be started. The indicator is controlled by the instrument panel cluster based on an electronic command signal from the PCM through the CAN. The on-time of the indicator 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 operating.
