Cooper Convertible (R57) L4-1.6L (N12) (2009)
Observe the following information for service:
General information
The following general data is provided for servicing the IHKS:
Running in the air-conditioning compressor
IMPORTANT: After replacement, allow the air-conditioning compressor to run in.
After replacement of the air-conditioning compressor or refilling the refrigerant circuit, the air-conditioning compressor must be run in. Running in is
required to ensure lubrication (oil distribution). Running in can only be carried out using the BMW diagnosis system.
For this running in, the air-conditioning compressor must be operated within the specified engine speed range. Here, the oil volume filled by the
manufacturer mixes evenly with the liquid refrigerant.
IMPORTANT: Do not exceed the specified engine speed.
If the engine speed exceeds the specified engine speed range, running in is aborted automatically. The running-in procedure must then be repeated in its
entirety.
Replacement of the electrical auxiliary heater
The electrical auxiliary heater can be replaced in service (the heater/air conditioner must be completely removed).
Coding and programming
Coding
When coding the vehicle-specific data, the following details (among others) are taken into account:
-
Engine variant (diesel engine or petrol engine)
-
Version of the control module (IHKS)
Programming
Flash programming of IHKS control module via the K-CAN is possible.
No liability can be accepted for printing or other faults. Subject to changes of a technical nature.
Integrated Heater Control IHS (IHS Integrated Heating Control)
Integrated Heater Control IHS
This functional description covers the integrated heating control, IHS. The IHS can be used to adapt the in-vehicle climate to the individual needs of the
passengers. Information is exchanged between the vehicle components involved via the body CAN data bus.
There are no differences for left-hand drive and right-hand drive vehicles. The control module with operating unit is always fitted in the same position in
the vehicle.
The control module has the following functions (see also individual functional descriptions):
-
Temperature control
-
Air distribution
-
Air flow control
-
Recirculated-air mode
-
Heated windscreen and rear window
Brief description of components
Control module/operating unit
The IHS control module records the signals of the IHS components and controls/regulates the heating process. The control module is at the same time
the operating unit of the IHS.
