Porsche Panamera 2015–2016 Coolant Fan Wiring Diagram (Hybrid & Non-Hybrid)

This official wiring diagram focuses on the Coolant Fan control system for both Hybrid and Non-Hybrid Porsche Panamera models (2015–2016). Designed for advanced diagnostics and electrical troubleshooting, the document outlines relay logic, control modules, fan motor integration, and fuse assignments. It enables technicians and electrical engineers to accurately interpret cooling system functions and integrate them into broader diagnostic procedures, particularly for high-performance hybrid systems where thermal management is critical.

Coverage includes:

• Dual Cooling Fan Control

  • Supports hybrid and non-hybrid configurations.

  • High-power fan motors illustrated with separate circuits.

• Power Supply Integration

  • Detailed mapping of fuses and relays specific to fan circuits.

  • Clear voltage supply pathways and protection logic.

• Control Module Communication

  • Interaction with Front-End Electronics (FEE) and Engine Control Unit (ECU).

  • CAN bus lines highlighted for signal transmission.

• Temperature Sensor Feedback

  • Sensor-to-ECU wiring for coolant temp regulation.

  • Links to additional sensors in hybrid models.

• Relay Logic and Actuation

  • Fan relay triggers via PWM signal or control ground switching.

  • Pinout specification for connectors and logic flow.

• Connector Identification & Wire Colors

  • OEM connector IDs, color-coded wiring legend, and function tagging.

• System Ground Points

  • Ground distribution layout specific to coolant fan grounding.
