Here is the expert solution to BMWDME/DDE module initialization problem

(Note: The document was translated from Korean. Credits to Mr.JIHUNX)

Background:

TheDME(Digital Motor Electronics module of theBMW automobile isa very important module that controls the main operation of the engine (Diesel vehicles include DDE and Digital Diesel Electronics modules).Unlike other modules, the DME / DME2 / DDE module must be coded with the power turned on (ACC On) without coding while the power is turned on at the time of coding.If theinitialization is done by pressing the button with theignition onCode,or the coding is done, the DME module will be blown and various warning lights willappear.Most of the beginner coders initializeECUs it, and after selectingall,Code it seems that these problems are caused by pressing.CodeIf you need to initialize by pressingCode, select the individual module and press to initialize it for each individual module.

If the DME module is blown, the starting will be turned off while coding, and if you try to start, there will be a phenomenon that the driving device error will not start.Then, various warning lights are turned on as shown in the figure below.

Solution

By default, the preparation process is the same as theBMW ENET E-syssoftware coding procedure.I am going to tell you about the theory, not the actual experience.Please note that the names and numbers of the coding files are different because they are synthesized by combining all screenshots.

1. Read SVT (VCM) Activate FA (VO) => Read SVT (VCM)),then proceed to the process(ACC ON state).
2. SVT With theDME module selectedin the area,Detect CAT for SWE clickthebutton on theright.

1. After selecting the most recent CAFDOK, press.The currentF020-13-11-504 CAFD list is selected becauseitis the most recent versionon the current capture screen.

1. TheDME modulewill probablyhave been changed to a blue, red color folder on the SVT list as shown below.

1. DME With the module name selectedCode, clickthebutton on theright screen.Oryou canDME right-click on the module nameCode and select the same.

1. If you continue to coded while the green bar is stretched as if you are coding, it is restored normally.
