The engine control unit will switch the air conditioning off under certain circumstances. That is the case if the engine load or temperature is too high, for example. As there is no additional AC cutoff relay, the engine control unit switches the relay K 60 off in the event of an overload. Trouble-shooting for relay K 60 is outlined in test step 31.
