Star not connecting to all modules

[Abcdescott]

Hi Everyone

So I finally managed to fix my Toughbook and get my star diagnostic working again however when I ran the health check I could only find detect the common rail diesel injection module.

As you can see from my attachment the rest of them just come up as not there, I have a 2004 ml270 so I think I should be able to do more... no ?

Thanks for the help guys.

Your battery status looks a bit on the low side at only 12V. Have you tried re-running your diagnostic tests using a battery charger attached to the main battery?

there is more than one canbus e.g. CAN C for engine - CAN B for interior systems and yet another for the Communication / Entertainment system. These can all talk to each other via the EIS [ ELECTRONIC IGNITION GATEWAY but function independently. Sounds as if a fault is pullling down the voltage on the CAN B SYSTEM as Wongle says- This can be a low voltage supply or a short between the signaling can H [ high] and can L [low] lines--- this can occur within one of the modules or more commonly in the CAN B wiring or connectors thro mechanical damage or water ingress [ door hinges area is a favorite -seat bases another anywhere there is wiring mechanical movement] Sounds as if something is pulling your CAN B bus voltage down?

As said when using Star put the battery on charge, nothing worse that it crashing when you using it.
You need a good charger as well.

Hi,
It might be that the ML 163 still used HHT for some control units, only later versions of Xentry I believed dropped the ability to read HHT cars.
Something that might be pertinent is that the 163 didn't have an EIS, even the later face lift models.
Despite that it does seem a bit light in what it has picked up (I dont think the stereo is picked up unless it has Comand and/or phone prep), I always leave the engine running when i plug the STAR in to eliminate any issues with battery.
I would always check the simple things first, check the OBD socket and make sure that none of the pins have been pushed back into the socket.

Hi Guys

Thanks for the responses so yesterday tried both testing it with a battery charger connected and the engine running - same result (especially with the circle being grey -if that's where you guys are getting the voltage from)
@grober but I will need to sit down and go though this to make sure im reading it correctly. If there was no communication or a ground fault - would the system not work or is it only for diagnosing it doesn't go inactive which is where we have the faults ? Thanks for that canbus sheet but will be a good read!
@andy27168 Thanks for that, how would I check if im running the later type of STAR that means I might not be able to communicate with the other systems but ill check the odb port later today

Hi,
Early cars the software was HHT, as the systems got more complicated became DAS, and now the cars are Xentry.
On my DAS with C3 Multiplexer I simply clicked on the DAS Shortcut on the desktop, and when i read a unit requiring HHT it would open a separate small window (obviously written in an older style format) over the top of the DAS window.
I now have a much later version of software with Xentry and a C5 Multiplexer on the desktop there is a Xentry and DAS shortcut, if I plug a car in requiring DAS I can click either shortcut, as the Xentry short cut when clicked will open DAS in a separate window over the top of you're existing Xentry window.
When I bought the later Xentry laptop it stated it no longer supported HHT as I haven't as yet plugged in a car that needs HHT I cannot confirm this, but it might be the reason why I have a separate copy of DAS on the laptop.
If you have a DAS and Xentry shortcut try using the DAS shortcut (if you havent already).
You could also try going into some of the control units you are displaying already, I suggest the cluster as I specifically remember that aspects of this control unit requires HHT.

awww ok makes sense. and so not sure if I should say or not but I got my xentry from … "a Friend" online lol so its a pass thru and the xentry version is 2019.05 maybe I have a too recent version comparable to the c5 multiplexer ?

I think that might be why you have 2 DAS shortcuts on your computer. do you think ill need to get an older copy of xentery/DAS etc ?

It depends on who has make your program installations, there is no problems even with newest softaware and windows 10 to use HHT but there was shortly period where K-line diagnostic was not possible in 64 bit systems. Usually program shifts automatically to 'lower' diagnose program but shortcuts to them should still be available.

If OP programs are just made in phase where HHT was dropped, this could be reason why diagnose fails.

 

[Abcdescott]

that might be the case then do you think upgrading to the latest install will bring it back or ? I have a 64-bit computer tried to install my version on a 32-bit windows but requirements were 64

 

[mersum1es]

Your programs has been tweaked to work in setup you are using... there might be HHT version available, it's easiest to get full disc image but nowadays programs must be activated each time to current setup after hardware has been changed (AFAIK not same than licence keys).

 

[andy27168]

Hi
Have you tried to interrogate the Instrument cluster yet? As it still could be a fault with the car.

 

[mersum1es]

true, all fuses checked?

Has in OBD or 38-pin socket? If 38, had you connector pushed 100% to bottom? And pins straight like suggested above.

 

[Abcdescott]

hi guys so @mersum1es your first post are you saying, get another software with HHT ? if so any ideas as the ones im looking up is just similar to what I have.
@andy27168 if you mean interrogating the system, by trying to get into it, im just getting errors. like it cannot connect to the unit etc.

how do I check pin 38 and the rest of the OBD terminals ?

 

[mersum1es]

Either get disc image where someone has solver the HHT problem, try install HHT alone yourself by following instructions. Doesn't guy you mentioned to install your current programs know about it? I send PM to you about one thread...

You cant connet to units if they have no power, they are not configured to system or you are missing certain pin contact in your diagnostic device. Which one you are using, OBD or round 38-pin?

Edit: you have declined converions so I cannot send PM...

Thanks @mersum1es I just got a download iso and done the install myself. Just messaged the "friend" I got it from and he says its not supported.

Im using a genuine j2534 with the passthru setup

Im not allowed to use PM's yet sorry man 30 posts Required. getting there lol I can give you my email and then remove it off this post if you want ?

It is just a link I wanted to share with you, I am not sure if you are familiar with that site already but sometimes it was not encouraged to link anythig to that forum... I will try my luck andput link here for a while https://mhhauto.com/Thread-HHT-in-WINDOWS-64bit

Was actually already on this site reading a few other posts but hadn't came across this. I will need to register etc for the files needed but I am familiar with the windows xp mode, used and installed this across the business a wee bit.

Thanks @mersum1es Ill try get this going and let you know how I get on.

I have had this with the copied systems before. Its normally a faulty multiplexer that is the cause.

Hi @BlackC55 yeah thing is I don't have a multiplexor im using a passthur device so no HHT for me, cheapest I could find was £320 … lot of money for just some fun. Do you guys know if a 1984 G wagon uses HHT at all ?
