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.

The glow plug control unit is mounted on the driver side of the engine compartment close to the air filter box. The glow plug control unit communicates to the Engine Control Unit (ECM) via a J1939 (250k baud) data link. The glow timing and intensity are calculated inside the glow plug control unit on the basis of controller area network signals provided by the ECM (engine speed, engine torque, engine coolant temperature, intake air temperature, air pressure, key switch, and engine state).

The glow plug control unit has three connections:
