Control Panel/Module Coding

Control Panel/Module Coding

The IHKA control panel/module is coded with the central coding key (ZCS) using the OE Diagnostic Tool. The ZCS coding procedures is the same as on previous systems.

After coding a new or replacement control module, disconnect it from the battery completely (unplug the control module from the vehicle wiring harness) for a minimum of 10 seconds. This allows the new coding data to overwrite any previous coding data.







Coding Conversion Features




Coding conversions provide flexibility for various system functions and allow a vehicle owner to customize the car's climate control system.

The E36 IHKA is capable of the following conversions:

- Temperature C/F
- Blower enhancement - increase the blower default speed (only possible from software version 37, introduced September 1995)
- Air recirculation - retain the recirculate air function for use at restart.
