Mercedes-Benz S350 CAN-BUS Troubleshooting with Star Diagnosis

Mercedes-Benz S350, chassis W220.

Symptom: This car is the breakdown vehicle which had been removed the whole car parts. After the repair, every time the owner start the engine and then turn off the ignition switch, the engine does not flame out and the meter lights are immortal. If the engine intake pipe is blocked and force the engine to flame out, the ignition switch can not locate in the ON position, that is, it can not go to the ignition switch. After disconnecting the battery power, the ignition switch can be turned and the engine will start, but the ignition failure remains.

Troubleshooting: First, I check with V2015.05 MB SD Connect Compact 4 and get the fault codes of DTC EIS control module and I am told that: bad ignition switch circuit 15, and the fault code can not be cleared. When I check the left front SAM, right front and rear SAM SAM and other control module, I find that the diagnostic tool can not enter the system. But data streams of EIS control module shows: 15R, 15,50, which is normal.

Now there are two main problems: first, the power control module SAM system does not work,  MB SD Connect Compact 4 Star Diagnosis can not detect the car and the fault codes can not be cleared so that the engine does not stall. When EIS control module is plugged, we use test light detect the control module circuit 15 joint EIS and find that there is still 12V power, and 15R, 50th line are normal. In principle, the 15th line is provided by the EIS control module. If I turn off the ignition switch or disconnect the plug of the EIS control module, 15th line should be 0V. So why is there 12V power on the 15th line? Obviously, this has nothing to do with the EIS control module, even if the failure rate of EIS control module is high. We continue detecting wiring diagram and find the 15th line is connected to many vehicle control modules including two fast control modules— the left anterior SAM and the right front SAM. Work to be done now is to find out which one control module or linae error provides power for the 15th line in EIS control module. According to the principle from easy to hard, I first press the plug on the left front SAM and right front SAM control module to determine whether when 15 and 15R in these two control modules plug, the ignition switch becomes normal and the engine also flame out normally. After turn off the ignition switch, we measure the left front line within SAM by multimeter and find that SAM output 12V power to the 15th line. Thus, after turning off the ignition switch, the 15th line still with 12V power results from part of the line fault in left Front SAM control module (but this does not prove that SAM control module failed).

After we check left front line of SAM, we find that when we turn off the green CAN-BUS connector, the engine can BE normally turned off and the ignition switch is also normal. In the left SAM control module, there are two CAN-BUS line connector, a group connected to the X30 / 6CAN-BUS control module, and the other is connected to the control module X30 / 5CAN-BUS. X30 / 6 connectors are located beneath the steering wheel (the top of the brake pedal) which is connected with EIS control module, the steering column module, AAC air conditioning control module, instrument cluster control module, UCP upper part of the control module, control module and the right front SAM Left Front SAM control module. Then we try our best to find the connector. We unplug the connector X30 / 6 one by one, and detect voltage with a multimeter on the CAN-BUS (the normal voltage is 0 ~ 5V). But when we check another CAN-BUS connector, fingding that the voltage is 12V while the other line is 0V. Obviously, when this one plug in, the CAN-BUS system does not work properly. When unplug the connectors, the ignition switch operation is normal. According to the circuit diagram analysis and see another Mercedes S350′s CAN-BUS connector, we are surprised to find that: when the joint X30 / 6 and X30 / 4 has a surplus CAN-BUS connector. These two joints in the factory are redundant (backup). The line voltage is 12V. These plugs can not be plugged into the X30 / 6 or X30 / 4. if they plug, CAN-BUS system is not working properly.

Finally, the 12V power connector on X30 / 6 and S30 / 4 will be unplugged and re-detect EIS control module. The fault code is no longer appeared on MB SD Connect Compact 4 diagnostic tool, and body control module on the left front SAM, right front SAM, SAM, etc. can be detected. The engine flames out normally. The instrument can work properly.

BA100 battery analyzer vs Quicklynks BA101 battery tester

Several vehicle battery testers are available in BA100 and BA101 are the top 2 most respected. They are completely two different products from different bands.

BA100 battery analyzer and Quicklynks BA101 battery tester main differences are displayed following points:

I. BA101 battery tester add new functions

1) BA101 increases cranking system test and charging system test.
2) BA101 increases EFB battery
3) BA101 increases quick test function
4) BA101 increases auto-storage function
5) BA101 increases Print function via computer
BA101 Batter tester
II The advantage for BA101 automotive vehicle battery tester

1) BA101 battery tester is manufactured by QUICKLYNKS tech which is a trust-worthy brand.
2) Four button for operation, more convenient for client. While BA100 analyzer is designed with 2 button operation.
3) Larger screen display, display more battery information shown as picture below:
BA101 battery tester
BA101 can shows the testing results in one screen, but BA100 only show one or two items in one screen which means BA100 must need five displays to show all information.

How to fix Citroen Picasso 2009 BSI flash problem using DP3

Car information:

Citroën Picasso 2009 with BSI and 95128 eeprom / Johnson Controls.

Mileage Tool to use:

Digiprog 3 (DP3)

Spend $179


Error description:

DigiProg 3 has done writing the new km value by “flashing” by OBDII “reading, verifying, writing” but only until 99 %.

Now car is “dead”, no functions anymore.

Need to tell also that i forgot to put extra battery charger, so this was happen when voltage dropped and now car is “dead”

Re-write with DP3 is possible apparently, recognize BSI number (but NOT the VIN) and does automatically pick-up the saved

“flash-file” and will try to recover, BUT DP3 don’t flash anymore when arrived @ 99%….

EEprom data looks okay

Put all FF in eeprom also don’t wake up the car.


Reference number on label:

PSA = 96 640 590 8002

V 05.01



boot 28120836-4

hard 28119248-3 C

BSI 04 EV K04 – 00 020309


Finally solved after all I managed to “repair” it as follow:

Please firstly look at the flash dump “BSI_JC_FLASH_M00″

full of area’s with “00″, so its corrupted in my opinion.

Each time DP3 will try to restore, also as commanded in the log-file, the original flash.
But for some reason DP3 take all time the “BSI_JC_FLASH_M00” and stops at 99%.

In the MCC card/storage there is some other 992 kbyte flash with name “BSI_JC_FLASH_01″ which is the +/- SAME as “JCI_BSI_678A”


This flash is the real original flash, and the “…M00″ is the modified flash.

Now the trick is : change the name from the “01″ flash into “M00″ and the “M00″ into “01″.
Then DP3 will AGAIN try restore the flash with of course “M00″, but this time the content is the good one because i “misleaded” DP3 by changing file-names

And indeed, this time until 100%, car start and you only need to re-do the whole procedure “read, verify, write” BUT THIS TIME WITH AN EXTRA BATTERY CHARGER .

Hope this will help some members with the same problem.

Tango, VVDI, tm100 which do spare Passat dealers keys

What I want to do?
I want to get tool to do spare Passat dealers keys. I am aware lost keys is eeprom job (tango).

Car model, year, engine:
I have Zedbull and this info is from the Zedbull homepage:
Pin code and CS is
extracted from the
*Vw can Bus 48 or Pcf7936
transponder must be precoded with
*If CS is 6 bytes and if Zed-FULL
says”No response”, Comfort module
eeprom file must be sent to IEA Tech
*If CS is 7 bytes, Zed-FULL will
precode the transponder.
Remote is programmed via OBD.
There is no known on board
programming procedure.
Passat B6(Smart key with 48 or
Pcf7936 transponder Cc(Smart key
with 48 or Pcf7936 transponder)
If the car is 2008+ comfort module
eeprom file must be sent to IEA
tech support.
If all keys are lost fuses as in
the picture needs to be short
circuited in order to Wake up
the ECU.
*Prox. Keys has Pcf7936
You need something that can read newer ECU,s as well.
You can use low cost option ECU reader clones, and post dumps and get 6th CS and PIN. And brute force the 7th byte via original key. Maybe you can use Zedfull for this?
There are several options here. It depends how much you want to spend.
If you spend even more money than you already have done, if even your MVP is also an original item. You can get the info directly on your PC. And do the job at once.

Tools recommended by experienced users:
1)Read ecu is wrong way, exist to many diffrents manufacture and types. Read eeprom from ccm is best and most secure way that you finish job with success. Tango, AVDI or TM100 is your solution.
2)If spare key, plug MVP, read PIN code and precoding data, put the data in Tango and search for 7th byte via exisiting key. Then write component security and lock transponder. At last, go to the car and learn the precoded key. Made 2 spare keys with MVP for Passat B6 2005-06 without any problems. If you can read PIN and precoding with MVP, you will succed.
3). I pull the comfort module on every Passat now, 20 minutes beginning to end for the complete job. If the customer has a genuine (with receipt) dealer supplied key then I will code that in, I cut the supplied transponder out and use a blank transponder coded by Tango, just like if it was my supplied remote.

Last Question:
Between tango ,vvdi, tm 100 which process doesn’t need soldering iron and which has wider coverage ?

For all of them you need read first 95320 with external programmer (xprog programmer v5.0 will do it). I make Passat ccm with clip in circuit without any problem.
