This topic is aimed at the growing number of members that have purchased MB Star diagnostic systems.

Post 1996 OB2 models are fairly easy to read, however the early diagnostic system HHTWIN encompassed within the very latest Star system is more difficult to get grips with, so this is a trial sticky topic to address any issues encountered using the hhtwin system.

In essence HHTWIN is a hi-tech version of our LED blink code readers.

I'm up first with this topic :)

With my 1993 SL500 I connected the C4 MUX to the 38 pin connector.

The "Short Test" ran but only one of the nine modules reported data for 'Gasoline Engine'.
Chassis, Body and Climate all reported no connection to the MUX!!!

Any ideas??

Interesting. I have not connected my SDS on cars earlier than 97, so I can't be much of help.

Can you connect to other modules individually? What does the short test say for the other modules? Does it show an exclamation mark? Like. -!- ?

James:


I have the 1995 SL500, and I am rather certain we share the same Engine, but not all the same Chassis, Body, and Climate Control systems.

When I look at the Fault Code Manual:

1) The DM Digital LH covers 1991 - 1996 M119

2) The ETC is from 1990 - 1995

3) but, ABS is from 1994 - 1995 only

4) RST is from 1990 -1993, or 1994 - 1996

5) SRS is from 1988 - 1993 or 1994 -1995

However, the HHT-WIN should cover all years from 1989 onwards.

When I ran HHT-WIN, I got everything for Engine, Chassis, and Body, but NO CC (Climate Control). 3 out of 4.

I assumed because the CC has its own built-in Diagnostic Output, HHT-WIN would be superfluous. However, I may be wrong about this.

I think your situation needs referring to one of the Trained MB Technicians who would know from experience if HHT-WIN can do all your SL's systems. I'm rather certain C4 should cover yours.

May be a glitch in the program on your particular SDconnect software and/or hardware.

God Bless, Arctic

Xentry took me to DAS, and DAS switched over (automatically) to good old HHT-WIN, again. Guess my 16-year old SUV's system is a bit ancient in the scheme of Mercedes-Benz technology.
From what I've seen:

All MB from late 80's to 99 = HTT-win
All MB from 2001 to 2009 = DAS
All MB from 2010+ = Xentry

The year 2000 is a weird transition period -- some MB made in 1999 but the model year is 2000 will be diagnosed from the 38-pin under the hood and thus use HTT-win. Other MB made in early 2000 and sold as a 2000 model will have the OBD port and the SDS will require the OBD cable to diagnosis....and will use DAS.

And then there are orphan cars, like some SLK models -- some 2000-2001 SLK require the 38-pin.

I've even seen a 2000 E320 that had both 38-pin and OBD port -- I could use either port to conduct a full diagnosis. That was funny.

I'll run it again today and take some screen grabs, also I'll run hhtwin on my 1998 SL500 which also has the round 38pin diagnostic connector.

Better luck with the '98 SL500, screengrabs later.

Another quick question, should I allow BGupdate to connect to the internet??

James:

From what I recall, BGupdate is an executable file, for 3rd-party programing, used by Windows XP-based Software Developers.

The MB STAR C4 software is fully loaded on your HDD, and there should be no need to use, modify, or reprogram STAR C4's software via BGupdate. Any attempt to do so, may result in a crashed STAR C4 program.

What I am doing with regard to any updates and internet connections is TO STAY AWAY from doing any of it.

I will not be going onto the internet with the laptop UNLESS required by the Seller's Technical Support to update or fix the software via TeamViewer.

If I wish to share anything off the STAR C4 screen shots, I'll download them from the laptop onto a USB Memory Stick, and then upload them onto the internet using my desktop office computer.

I plan to completely isolate the STAR C4 laptop and its software.

On another note, I will start posting some useful MS Word and PDF documents regarding STAR C4 Diagnostics on this Sticky.... stay tuned.

I'm pleased to hear that you had better results with the 1998 SL500. :smile

God Bless, Arctic

Thanks Arctic, that's what I thought about updating.

I'm still puzzled with HHT-WIN, with my '93 SL500 and '98 SL500. I can access RV with the '98 but not with the '93!

I still have to copy screengrabs via a USB stick to my desktop PC to upload the images...... Or can I go online with the thinkpad and login to BenzWorld without the SDS system updating and "Bricking"?

I have a C3 system running in a virtual machine on an external drive.

I would not allow the system to run updates. There's no reason to, and if it breaks your DAS system you're pretty much screwed.

I would keep it sandboxed and never let it connect to the outside.

Correct. Always keep your SDS separate from everything else -- don't even let it connect to routers etc.

I only use the BGupdate to update the Connect4 to the latest version so it could work with 2014 xentry. Previously it was on 2011 version.

And even then, it wasn't connected -- I downloaded a cooked update file that was specifically designed for clone SDS connect 4.

Screen shots as promised:

These are from my 1998 SL500 and as you can see HHTWIN will not connect to some of the modules.

With my 1993 SL500 you can see that there is no connection to the RV module whereas in the screenshots above from the '98 SL500 it connects perfectly :confused:

Nice posting on your screen shots! .:goojob:

Does your RV (soft top) module respond when you use your Flash Code Reader?

If RV does respond with Flash Code Reader, then your problem isn't the Control Module, but something wrong with the cable or hardware/software.

I'm assuming you are keeping a 2-amp Battery Tender constantly hooked up to your SL's battery during all these tests.

RV responded perfectly on my 1995 SL500 with the STAR C4.... the RV Module had stored a number of fault codes from when I had Klaus recondition all the hydraulic cylinders, and I was having to move parts of the soft top up & down to do the removal and re-installation.

I don't think it's a problem with his software, per se, but more like the car is too old....that, or the CAN network (or whatever the hell they call module to module communication in those days) is disconnected.

You for sure need to be able to connect to the engine ME. The fact that you are unable to points to a cable fault in the car.

Pull out some wiring harness and trace the diagnosis wire from the ME to the 38 pin.

Ps. Thanks for the post in the sticky! Makes me feel all important and stuff. :D

Glad to be of help.

EDIT:

What kind of fuel injection does the 93 SL use? EFI, or the older CIS or HFM?

Thanks for all of your help and suggestions, and your contributions are very welcome


I don't think I have wiring harness issue because this car was bought, used and driven in Germany until exported to the UK in 1998, so any wiring harness issues would have been recalled and addressed prior to my buying the car in 2006.

I'll plug in my LED break-out box tomorrow and post results.
If it makes any difference, the hard/softop has worked flawlessly since I bought the car in 2006, and has always registered one blink on the LED "PAPER-CLIP" system.

The 1993 SL500 has Bosch LH-Jetronic 4.1:)

ALL STAR C4 Users:

I wanted to attach the following MS Word documents:

1) Handy STAR C4 German-to-English Translations

2) Mercedes Fault Code Listing

3) How To Activate EPC & WIS Programs

4) How to Activate Xentry Program

but each of these instructions exceeded the allowable file size for BenzWorld...:crying

Maybe Redliner can allow an exception?

God Bless, Arctic
