NOTE:
- If compressor shutoff criterion is present ( Display group 002), A/C Compressor Regulator Valve -N280- cannot be actuated; this also applies during output Diagnostic Test Mode (DTM). Output Diagnostic Test Mode (DTM) (Function 03)
- A/C Compressor Regulator Valve -N280- must not be actuated if pressure signal is not detected by High Pressure Sensor -G65-.
- Climatronic Control Module -J255- calculates pressure in refrigerant circuit by way of duty cycle (display zone 3).
- If refrigerant circuit has been correctly filled, pressure will be 2.6 bar at a temperature of -3 degree C. To avoid a malfunction being stored at low temperatures, Climatronic Control Module -J255- does not register a refrigerant circuit malfunction until pressure drops below 1.8 bar (occurs at -12 degree C). High Pressure Sensor -G65- is however no longer checked at this temperature.
- The permissible specifications can be found in the table stored in the "Guided Fault Finding" function.
