what does error code B10C1 mean for my Porsche Cayenne E3 (2018-Present)?

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, basic hand tools, refrigerant gauge.
• Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Wiring and Connectors

• Sub-steps:
  • Remove the interior trim panel to access the HVAC control unit.
  • Visually inspect all wiring and connectors for damage.
