Climate Control In Diagnostics

Climate control will operate in whatever mode was being commanded just prior to depressing OFF and WARMER buttons, upon entering diagnostics. Even though CCP display may change just as buttons are touched, prior operating mode is remembered and will resume after diagnostics is entered. Extended Compressor at Idle (ECI) is not allowed while in diagnostic mode. This allows observation of system parameters during normal compressor cycles.
