Note Regarding Version Coding

Version coding with HHT
a) Version coding can be performed automatically and manually only with the Hand-Held Tester.
- Automatic
Before removing the IFI control module, read existing version code with HHT. After installation of the new control module, enter the previously read version code (menu program in HHT).
- Manual
If the code number can not be read, the vehicle equipment/version must be determined. The corresponding code number is obtained from the Spare Parts Microfiche, Group 54 and manually entered with the HHT.

The following vehicle version data must be observed for coding:
- Vehicle model
- ABS
- Manual transmission
- 4-speed automatic transmission
- With cruise control
- Without cruise control
- ETS
- Country version

When returning a new control module to a PDC, the code number must be erased.

Trial installation of a control module from an other vehicle is not possible. Trial installation of a new control module from spare parts stock is possible, but only to a maximum of 40 engine starts. After 40 engine starts, the control module is permanently assigned to the vehicle.
