Manual Input of ZCS Code
WARNING: This page does not describe the selected car, but rather 136 other vehicles, including the 2008 BMW 760Li, 2008 BMW 650i, 2007 BMW Z4, 2007 BMW X5, and 2007 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
Currently when replacing control modules that store the ZCS code (IKE/KOMBI and EWS) the code is read out from the faulty module and stored for later coding. When replacing modules that store the ZCS on earlier vehicles, it requires that the code be read from the vehicle ZCS label and entered manually.
The control modules that require manual input are:
- IKE (E38 up to 1/95).
- EKM (E31).
- Instrument cluster (E32/E34 after 9/91 and E36).
- EWS II (E36/5 and E36/7 up to 9/98).
For later vehicles, as long as the defective module can communicate automatic coding is possible. If the data can not be read (module cannot communicate) then the ZCS code will be retrieved from the redundant location.
