9-5 Linear Sport Wagon (9600) L4-2.3L Turbo (B235) (2002)
When the control module grounds the output, the solenoid valve opens and creates a vacuum on the shut-off valve, which in turn stops the flow of
coolant.
The control module closes the shut-off valve if the requested mixed-air temperature falls below 6 °C for both zones (both zones must be cooled
considerably).
Diagnostics
In the event of an open circuit or short circuit, diagnostic trouble code B2375 is set and 18 is displayed instead of right-hand temperature when
calibrating.
