 | If replacing the control unit, it is essential to carry out the self-learning procedure using the Examiner diagnostic equipment. This procedure allows the engine management control unit to identify the presence of the new air conditioning control unit and to correctly set the parameters necessary for the system to function correctly. The presence of the air conditioning can be deduced when the ignition key is in the MAR position, when a passenger compartment interior climate control system activation request is present for at least 8 seconds. After recognising the presence of the climate control system, the engine control unit will activate the diagnosis, controlling the activation relay. |
