Coding Code (Code Number)
E32 and E34 vehicles produced from 9/90 to 10/91 were not ZCS compatible. For this limited range of production a coding code is required in order to properly code the following control modules
- IHKR 2 & 3
- EDC III
- DWA
All other replacement control modules (except DME) within this production range are precoded at the factory.
The coding code is a single digit. Like variant coding, the code is entered via the DISplus/GT1/SSS. By entering a valid code into the module a set of operational data specific to the code entered is assigned to the operating program of that control module.
