IHKA E36 Control Panel/Module Functions

The control panel/module handles all the functions necessary to operate the IHKA system:

• Blower speed
• Auxiliary cooling fan
• Air intake flaps (fresh/recirculating)
• Air distribution flaps (face vent, foot-well, defroster)
• Heater core temperatures
• Evaporator temperature
• Special programmed functions
• Rear window defrost timing

And, like the E38 control panel/module, the E36 version has an EEPROM for fault code storage. The module can go into "sleep mode" to reduce power consumption when the ignition is switched "off," but still retain control panel settings and fault code information.

Another feature, unique to the E36 control panel/module  , is that temperature sensor readings, "Y-factor" values, software version and other information can be displayed on the panel face for diagnosis.
