GF07.16-P-3010P CDI AC Compressor Shutoff, Function
ENGINE 642 in MODEL 164.8 /1, 203.2, 251.1, 203.0, 251.0 up to Model Year 2008 /AEJ 07
ENGINE 642.9 in MODEL 463 up to 31.5.12
ENGINE 642 in MODEL 211.0 /2, 219.3, 211.6, 209.3 /4

A functional requirement for the AC compressor shutoff function is the AC system is running. The CDI control unit (N3/9) receives the message "COMP_ON" (refrigerant compressor (A9) activated) over the Controller Area Network bus Class C (engine compartment) (CAN-C) from the EIS [EZS] control unit (N73). Where the following requirements are met, the CDI control unit interrupts actuation of the refrigerant compressor:
^ Engine speed less than 2000 rpm
^ Value of the accelerator pedal (B37) greater than 95 %

If the conditions for the AC compressor shutoff function are no longer satisfied, then the refrigerant compressor is reactuated by the CDI control unit.
