Where it lives

For P2C78, start at the module the description names.

Check these first

• An active grille shutter module D that overheated from a binding actuator
• A shutter D actuator drawing high current
• Repeated stalling of shutter D against debris
• A module D driver stressed by a shorted actuator

What to do next

1. Read active grille shutter module D temperature on a scan tool
2. Command shutter D and watch its current draw
3. Inspect shutter D for debris or binding
4. Test the shutter D actuator for a short
5. Replace the active grille air shutter module D if it keeps overheating
