Thanks, Jim! Now in the Encyclopedia!

 

Thanks Warren, It's great to be able to contribute

 

Hi - I saw your thread on how to remove the Tele Aid module completely and found it very well written. Since you seem comfortable with the Command setup I thought you might be able to give me a little insight. I have a 2004 SL55 with the MOST setup. Last fall I hit a slight bump and I had my radio cut out, along with getting the SOS Tele Aid error and of course the SRS light. I hadn't planned on troubleshooting this myself, but to shorten up a long story I ended up retrieving my car from a local independent this spring, still not fixed, running rough, and the interior half disassembled. I picked up a C4 tool and I have been cautiously troubleshooting this. I have not taken any modules out of the ring at this point, but did deactivate the tele aid and the E call. I had thought that the Tele aid was grabbing the audio and muting it trying to make a call, but that wasn't the case. I am getting errors in the ring, and it appears that the ring is getting broken at or before the cd player since the user interface is showing no cd player and no telephone. Diagnostics shows a N1111-002 error, which indicates that the second module in the ring is offline. Do the optic connections go bad? My cd player at least powers up yet and will eject the cd cartridge. Besides removing the rest of the panels in the back of my car and checking fiber connections I'm wondering if there is something else I should be looking at. When I removed the E call feature from the air bag it got rid of the airbag errors, so that tells me that it was a failure in the chain of something besides an air bag fault or a Tele aid fault. Thoughts?

 

remove the CD changer from the optic link with a coupler to keep the link intact and check for comand sound from radio.
I sent u a more detailed private message since you pinged me there as well.

 

mis understanding the fiber optic loop system

As I was reading the thread that Jim/Jnash was speaking about here, I find myself in a situation that i can't seem to find much info on, as I have read and re read the encyclopedia from Warren, and other similar situations, but still find myself in a quandary.
About a year ago i had a large water leak in the rear left corner where all the audio/tele components are located. As you can imagine, all needed replaced or fixed due to some level of water damage.
No sound for anything, lead me to start with the Amp to be fixed at a reputable electronics store here in the Dallas area. Then it was on to the cd player, then the PSE and VR components for the hands free phone. After getting all different components, everything came back except the hands free phone. Even the blue light on the puck in the middle console lit up, and showed on my phone as well, that we were connected by bluetooth. But, as i got and or tried to send calls, .... nothing. So, i re-purchased a new PSE and VR component cleaned up the fiber optic wires, straightened them, as i had read that even a small bend in the line can cause trouble.
Still, nothing. I laid it on the back seat for a few months, dealing with a couple other issues, but now that those are taken care of, i would really like to get my hands free back for driving. Is it possible it can be the Tel Aide component you spoke of in the thread earlier that is analog, that may be causing it to not work? Even though its no where near where the water took care of the other components nicely a few months earlier!!
So, just asking for any thoughts or ideas you may of, or anyone has come up with to either circumvent this or get the correct part fixed??
Thank you so much!

If you have sound from at least one component even the radio then your fiber loop is working. You can take the Teleaid out temporarily with a optic bypass connector to see if helps the phone to work. But my guess it's that it doesn't.
What does star diagnostics say about the audio/communication system?

 

I haven't gotten anything from Star. The dealer says that they don't deal w the old PSE or VR components anymore so they didn't have any info. I will find someone that can diagnose it w Star to see.
When/if I take out the Tele Aid out, you mentioned it goes from Analog, to digital? I can run the system without the Teleaid all together, correct? Does it change the sound from all the components that were on the analog system w Teleaid?
In the end, did you replace it with all new components?

 

No. Nothing changes from to analog to digital. Teleaid is as old cell phone connection for emergencies that's connected to Mercedes version of OnStar. It's the unit that would call home if your car flipped over or you pressed the red emergency button. But since mb doesn't support analog cells anymore Teleaid is useless and you can take it out as long as you insert the fiber connector to keep the loop intact. There will be an error on the cluster unless you code it out using my procedure.

 

And you procedure is what you talked about earlier?Do you have it broken down in any way for some of us that are really technically challenged? Thank you so very much for taking your time out to deal w this!! Truly appreciated!!
Scot

 

Hi Scot, yes the TeleAid removal procedure is the one shown at the top of this thread. I thought I wrote a pretty detailed step by step guide on how to remove it. If this is beyond anyone's comprehension I can only suggest some one else performs it who is familiar with STAR diagnostics. That being said, I'm up for improving it it anyone can add value.
I am doubtful that it will cure any issues with the cell phone puck that is reported as connected to COMAND but no sound, but at least TeleAid is one less thing to have to have in the fiber optic audio loop.

 

Have not used this forum to respond, so hopefully this will work.
Jim,

Do you know if the X431 can reset these codes as I do not have the Star Diagnostics?

Thanks for your help.

Doug.

 

Hi , Sorry I know nothing about the capabilities of the X431

 

I changed the codings in Cluster, CGW, and Airbag.

I got one of those big red warnings on the dash about SRS malfunction or something.

So I went to the Airbag section to try to clear the error, and it said that the error was the coding. I tried to reset it, but it just came back.

So, I just went back to the Airbag section and marked emergency call as PRESENT to get rid of the red light.

 

I went thru this a bit ago and remember a NOTE in DAS about leaving the Airbag coding as is. Apparently there is a starting self test where the airbag to teleaid circuit is checked. If there is one, all is well and no errors. If you code out the E-call from airbag, SRS unit thinks something has gone awry and throws error.

My best guess is leave the air bag coding as is with E-Call present. It will pass SRS startup check then. No reason to uncode it as there will be data passed ONLY if the airbag deploys. If that happens you have bigger problems to think about.

 

Ok, I have done the SDS part, now I am looking for the actual location of the Tele-Aid module where I may find the D2B connector so I can terminate. The Star Finder shows it to be either under the rear seat on passenger side, or behind the rear seat in the trunk?

Can someone point me to the real Tele-Aid? My car is 2001 S500 USA model.

Thanks in advance.

 

Hi,

Go into SDS Quick Test, make a note of the Tele Aid Module number N/xx, either click on that number and it will automatically show you where it is located or come out of SDS and manually enter it into Star Finder and it will tell you the location.

Dean, @pinkster , will know the correct way, I haven't done it in ages and can't remember the exact procedure, my head is currently very involved in VAG Com and a V10 Diesel VW Touareg

HTH,

Cheers Dave

 

Dave's post will get you there. Unfortunately, I don't recall the location in a D2B equipped car; in a MOST bus equipped car, it is under the rear seat, passenger side.

 

It indeed was under the rear seat right side.
Already terminated by PO, I removed the box.
As for the trunk, I purchased D2B connectors, no need to do that as the connectors are already there to terminate any removed module, (CD, AMP, VR....) or remove them all and terminate.

Another thing to do on the S600 TT since the interior's out at present.

 

Update: I removed the Tele-Aid module under the rear passenger side seat (USA version 2001 S500) after and it threw SRS warning light on dash. I read someplace before that the Air-Bag searches for Tele-Aid on startup, so I figured that was the problem.

Tried to find this actuation in SDS but could not get into AirBag (probably something to do with my Right Front Sam not communicating. I also had read that removing the initialization in AirBag does not work either.

So, I had to remove seat and replace the Tele-Aid module and connect the big wiring harness. D2B is disconnected and terminated to loop.

Just a FYI for anyone thinking they can remove the module (Tele-Aid).

 

Hi,

You need to get communication with Airbag will need to re code that one for sure !!
Probably also go into other Modules such as EIS and UCP .................... It's not "Actuations" that you need .....................

I've never done this job before, but at a guess it is "Coding", or "Initial Start Up", then you have to code it as Tele Aid "NOT PRESENT"

I don't know exactly how many Modules will be looking for Tele Aid, never needed to mess with it
Certainly it will need Coding "Not Present" in SRS (Airbag) Module, also UCP maybe EIS.

@pinkster , Dean, may be able to help here he is very good with simulating on SDS and looking at stuff, will be able to probably tell you the exact steps.

I'm just guessing above so don't take that as "Gospel" please, lets see if anyone else can elaborate before you get into coding stuff off :wink

Cheers Dave

 

Here we go, from post #1 LOL

Several modules are affected that need to be coded differently in SDS as follows:

Cluster->Control Unit Adaptations->Variant Coding->special equipment “Set TELE-AID or E-CALL” = NOT PRESENT.

Cluster->Trouble Shooting by means of complaint or symptoms->Following Engine Start the Message “TELE AID Defective visit workshop” appears in the display->set “Instrument and communication system” = NOT PRESENT.

Airbag->control unit adaptations-> Read codes and change if necessary->vehicle equipment->Emergency Call or E-CALL = NOT PRESENT.

CGW-> control unit adaptations-> Read codes and change if necessary->COMAND or AUDIO-> Cellular Telephone = NOT PRESENT, (not sure if this was required, but it did not affect by Bluetooth puck into the COMAND.

 

I just tried to go into EIS to check for AC 50 second delay, and I could not find EIS in my list. I will do some Simulations and try to learn more

On the ^^^^ I did use that reference, but I cannot open AIRBAG. I have made the changes in CLUSTER.

I don't understand or find CGW??

P.S. I have a used Right Front SAM coming.

 

Trouble is you can't simulate everything, I've tried it a few times and found it very irritating, Dean seems to have better luck than me

I just hook to the Cars these days and explore.

I'm not saying it is an EIS coding probably not, especially bearing in mind my second post here today above Looks like you gotta code it out of Airbag first, and probably Dash Cluster to avoid a written message

 

Yeah, I believe I may have cut my cords in the wrong order, probably should have done AirBag first, then remove in the other places. When I get the new SAM in and programmed, I will try again.

 

If you have SDS then you can check the "Function controlled by more then one module" and see all the modules that you need to check. Also as the car is a pre-facelift you don't have a CGW. You will need to make sure you get all of them done too.

Off the top of my head I believe if you just go to the emergency call under control modules => communication, it will tell you that it is no longer active and what you need to do with it.

Hi Dean,

Thanks for the reply

OK so where do I find "Function controlled by more than one module" ??

I don't recall ever seeing that one
