Climate Control system calibration - Alfa Giulia

[dusan147]

I have problem with connecting of brand new humidity sensor for Alfa Giulia. Two bought sensors don't work and I have errors in MES.
Maybe is the solution to perform "System calibration" in the "Adjustments" subsection
of section "Comfort seat and wheel (CSWM) Bitron" for recognition of new sensor?
It is illogical, but in the section "TRW climate control (Automatic)" there is no any kind of system calibration.

have you enabled it in proxi?

Factory original sensor works few days (but with intermittent errors) and then it stops working (shows present error).
After removing it from system and wait few days out, I reconnect sensor again and it works few days.
Described "works - pause - works - pause - ..." behavior is annoying and I bought two new sensors.
Both new sensors don't work in any way.
I don't remember that "humidity sensor" or something similar is on PROXI list.
What item on PROXI list is dedicated to humidity sensor?

what errors do you get?
sensor is on LIN bus. check body ECU, HVAC for any abnormal errors. could be problem somewhere else.

B1938-96 - Humidity sensor - Component internal failure.
