I have figured out how to change the serial number of the VCM2 as well as enter test mode, and get a root shell on it.

You’ll need a microSD card for this to work.

1. Use IDS 86.

2. Recover yourVCM2.

a. Describing how to recover is beyond the scope of this post. Search the forums for instructions.

b. Afterrecoveryyour VCM2 should be at VCM2 FW version 2.1.1.5.

3. Wait about 90 seconds after the VCM2 beeps before proceeding. We are waiting for the SD card to be populated.

4. Unplug the VCM2 and eject the SD card.

5. Mount the SD card with alinuxmachine.

6. On the SD card open ‘apps/ vci- diags/ hwtest-scripts/self-test.sh’ for editing.

7. Add the following line to the file:

touch /etc/ vci/config/ testmode

8. Cleanly unmount the SD card and insert it back into the VCM2.

9. Plug theVCM2 unit into the computer and wait 90 seconds past beep before proceeding.

10. Launch IDS.

11. Go to system utilities

You are now in the test mode web server.

a. To set a new serial number select ‘Set New Serial Number’ and proceed with serial number setting.

The default serial number is: 1211-31605352

b. To get a root shell Telnet to 192.168.171.2 you will be dropped to a root shell without providing login credentials.

c. To stay intestmodeat next reboot select ‘Set Repair Test Mode’. This has to be done once per boot or you will have to go through this whole process to re-enable test mode.

Here Be Dragons:

To those who would go poking around , tread carefully. I accidentally rancgi-bin/total-reflash and wiped my VCM2.

My bootloader was stillintactedand available on pins 24 & 25 of the HDL26-PL-B connector.

Here is a tutorialofhow to do it: useSD connect C4mux to enable tank info & L/100KM into KM/LmercedesW211 (W203) (w221) and more

InDAS Developermode:

Kombiinstrument->DiagnosenachWerkangabe->Steuergerate-Anpassungen->

If youallsowanna adjust the way fuelconsumtionis showed

if you watch your InstrumentCluster ,you notice that scrolling through themenu , nothingchanged .

Forthis ,the "Kombiinstrument ”needs a reboot.

to do this inDevelopermode we go back by hittingF1->3times

For adding cruise control on vito viano w639

It is not my discovery, i find that on internet.

Add cruisecontrol / limiter to your Vito/Viano W639 it’s configuration.

This should work for all W639 till AJ08

InDAS Developer modetested version 10-200

Used withSD connect C4multiplexer

In engine control unit:

Entwicklungen (Development data) ->F3

Password : flexecu ->F3

Steuergerate – Anpassungen (Control unit adaption) ->F3

Steuergerate-Anpassungen (Variantencoderierung) ->F3

VCD_Transporter->F3

a Pop-up tells you : "Mindest eine Codiereinstellung ist ungultig” confirm -> OK

Here you will find the option settings

write down the line that is blue.

For example : NSG or NAG_Klima_Wasserstandschalter

Now we search for the string that contains the same options + Tempomat and Begrenzer

So that will look like : NSG or NAG_Tempomat_v-Begrenzer_Klima_Wasserstandschalter

Once you find it , click it and confirm with ->F3

"Soll die Codierung in Steuergerat ubertragen werden ?”->F3

JA or YES->F2 to proceed

Now we log out the engine ecu and go to the :

Instrument Cluster ( Kombi instrument) (Magnetti Marelli)

Steuergerate-Anpassungen (Variantencoderierung) ->F3

Variantencoderierung Algemeine Daten->F3

Scroll down untill you see "Limiter” set to Ja or Yes ->F3

F2 -> F1 -> F1

Ansteuerungen -> Gesamstliste aller Ansteuerungen ->

Scroll down untill you see the line : Steuergeraet Resetten (PowerON-Modus) (FN_Reset_SG_Power_ON)

Press F3 and confirm again with F3

Now you will see the "Kombiinstrument” reboots

Cruise control coding is added succesfully to your W639 now
