Solved! MB SD C4 “00” Icon and Initialization Multiplexer Failed

Problem:

I got the MB SD C4 Xentry and EVG7 tablet full kit.   EVG7 displays “00” icon on Toolbar.  Also failed to configure SD C4 main unit.  How can i fix it?

Xentry Software displays error:

Initialization of diagnosis multiplexer failed

Autonumen.com engineer working solution:

Run an sd connect c4 firmware update:

Go to C:\Program Files\Mercedes-Benz\SDConnect Toolkit, change update_automaticx, update_manualx and update_specicalx 3 files to update_automatic, update_manual and update_specical (delete the x letter).

Go to C:\Program Files\Softing\Diagnostic Tool Set 8\8.03\Interfaces\DCDI_DPduApi\eCOM_Toolkit, change update_automaticx, update_manualx and update_specicalx files to update_automatic, update_manual and update_specical (delete the x letter)

Restart computer update change the files’ name.

Install 6 AA batteries to SD C4/SD C5 main unit  (* SD C4 Item No. SP100-E does not require battery installation)

Connect OBD main cable with vehicle with 12V adapter.

Right click on lower right corner of the computer and select Administrator, then choose Software Update

Update 01_Bootimage_2_3.zip, 02_CSD_2_10.zip and 03_PmPic29_Cpld13.zip three files one by one until succeed.

Note: The update process can be applied to SD Connect C5 clone as well.
