Determination Process

Never order a replacement basic control module or EPROM directly from the parts fiche or EPC. ALWAYS USE THE MoDiC DETERMINATION PROCESS!

Programming VX.X software provides a feature known as the "Determination Process". It is extremely important to perform the determination process correctly and follow all instructions in this section.

[1][2]DME Programming required by a direct result of a service action or recall will be covered in the specific SI Bulletin. Each bulletin could have different procedures due to the specific DME being reprogrammed. The differences can cause unique messages to display in the MoDiC. Always read the SI Bulletin thoroughly and become familiar with the possible unexpected display messages before attempting any programming.

Prior to any programming, it is good practice to review the vehicle history file to see if any previous programming was performed. There may be a program added to the current EPROM that will not be recognized by the determination process or the new programming will not include the previous addition. Only after performing all specific dealership procedures should the technical hotline be contacted.

The determination process is used in all programming procedures:
- Customer Service Measures,
- Basic control module replacement and
- EPROM Replacement and Programming

With the MoDiC connected to the old control module through the diagnostic link, the software interrogates the old control module for proper identification.
It also recognizes any updates that have been added previously to the old EPROM.

With the determination information stored in the MoDiC memory, the programming software:
- Suggests updates for the connected control module (Service Measure)
- Provides the part number for the replacement
- Basic Control Module
- EPROM
- Reuses the data when the replacement control module or EPROM is programmed as long as the MoDiC is not used for another purpose after the determination process.
