DTC Description: Notes

WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

Glow plugs provide rapid heating of the air inside the cylinder to aid in starting the engine during cold ambient conditions. The ceramic glow plug heating element extends into the combustion chamber area where the fuel will be injected. The voltage supplied through the glow plug control module is grounded through the cylinder head. When the glow plug control module commands the glow plugs to activate, the Wait to Start Lamp will be commanded by the ECM to turn ON. Allowing the Wait to Start Lamp to shut off before cranking the engine will ensure that the optimum conditions for starting are present in the cylinder.
