The glow plug control module is located in the right front side of the engine compartment.

There are three phases of glow plug heating:

The Powertrain Control Module (PCM) determines the power levels for each phase and heating times from the coolant temperature.

When the stop/start switch is operated to start the engine, the PCM calculates any required heating times and, if heating is required, sends a Local Interconnect Network (LIN) bus signal to the glow plug control module. The glow plug control module energizes the glow plugs with the required power levels. If required by the PCM, the glow plug control module keeps the glow plugs energized during cranking and for the duration of any post heating phase.

The glow plug control module monitors the drive circuit of the glow plugs for plausibility of operation, continuity, and short and open circuits. If a fault is detected, the glow plug control module sends a signal to the PCM, which then stores a related fault code.
