Wiring Harness on Valve Block, Connection Diagram
WARNING: This page is about a different car, the 2024 Audi SQ7, 2024 Audi Q7, 2023 Audi SQ7, and 2023 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.
- The valve block valves -1- are currently identical in construction. They are allocated through the wiring harness connector assignment -2- and are activated accordingly by the Thermal Management Control Module -J1024-. Refer to
Wiring Diagram.
- The allocation and activation of the valves (Refrigerant Shut-Off Valve 2 -N640-, Refrigerant Shut-Off Valve 3 -N641-, Refrigerant Shut-Off Valve 4 -N642- and Refrigerant Shut-Off Valve 5 -N643-) in the valve block -1- only occurs through the layout of the wiring harness connectors -2-. If the valve block is installed turned at 180 degrees in the bracket and the wiring harness is connected correctly as shown, this changes the function of the individual valves (they are mirrored), but the function of the valve block itself remains the same.
