The solenoid valve is supplied from +54 via fuse 31 and is controlled on the ground side from the ACC unit's K1 pin 14.
When the control module grounds the output the solenoid valve opens and releases a vacuum to the shut-off valve which in turn shuts off coolant supply.
The control module closes the shut-off valve if the required blended-air temperature is below approximately 6°C for both zones (both zones must be
cooled down considerably).
