Wait To Start Light: Description and Operation

ENGINE CONTROL COMPONENTS

Glow Plug Indicator Lamp
The glow plug indicator lamp 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 IC 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 ignition cycle even though the glow plug system may not be required.
