There are three phases of glow plug heating:
- Pre heating
- Crank heating
- Post heating.
The Powertrain Control Module (PCM) determines the heating times from the Engine Coolant Temperature (ECT) sensor. The lower the ECT, the longer the heating times. If the ECT sensor fails, the PCM will use a predefined temperature as a default value.
The PCM monitors the feedback from the glow plug control module. If a fault is detected, the PCM stores a related fault code and permanently illuminates the glow plug warning indicator while the ignition is on.
