How to exit CALIBRATION MODE in IHKA climate control module R53
I hope you can help with this issue since I'm baffled by it.
I tried IHKA diagnostics to try to fix foot air vent function but i ended up being stuck on loop on Mode 2 (calibration) even after switching the ignition off or unplugging the car battery for 5 minutes didn't work.
Now when starting the car it shows "CA" which indicates Calibration mode starting and I hear the vents opening and closing them just shows "FF 01" which indicate Solar Sensor error and I can't exit or change to other modes when pressing "OFF" or "+" instead I can't switch on the A/C at all.
What make things worse is that the car isn't mine and i was trying to help fixing the problem, secondly I don't have access spare Solar Sensor to replace and check if it solve the problem.
Thank you in advance.
I really appreciate it.
