LEMON is the spiritual successor to CHARM, I recommend you try it!

ZCS Electronic Storage Locations




ZCS Electronic Storage Locations




A master copy of the ZCS is stored in the vehicle electronically to provide the coding software a source for retrieval. The ZCS code is stored in the Instrument cluster or EKM and redundantly in the EWS module on vehicles produced from 1/95.

On vehicles that did not have a diagnostic link to the cluster (E36/5 and E36/7 up to 9/98) the ZCS was only stored in the EWS.

The ZCS code may be read out and printed using the DISplus/MoDiC coding software.
