RECOMMENDATIONS

 No failure must be present or memorized.

The injection computer is not noticing the air conditioning starting control.

Check the insulation and continuity on the line from pin 23 (climate control of type Info Power
Absorbed by compressor) or from pin 46 (climate control of type Logical connection) of the injection
computer.
Mend if necessary.

  

If the problem is persisting  consult the climate control diagnostic.

AFTER

Restart the conformity checking from the beginning.
