- Should you suddenly lose your command system sound (radio, tape, cd, navigation, phone), you may have one of two issues: 1) either you have a bad 20amp amplifier fuse located in trunk, or 2) your Fiber Optics (orange cable) signal is disrupted between the Command System in the Center Console and the units in the trunk. This is a very easy fix that only should take less than an hour and $4 to fix.
Bro y havent i found this before meanwhile the techs wanna tell u its a special tool to troubleshoot masood u the man brother💯
Thanks, brother.
Nice video found the part on ebay had to use the part number to find it but when i received it today it took about 2min and i put the cords in and what do know a whole lotta sound thanks bro
Hi E Hill, so glad it resolved your sound issue. Thank you.
Great Video, Thanks.
Thank you.
Hello, when replacing the amp is there a reset procedure?
after changing the amp I still have no light coming out of the amp.
Hi Frederic - I am not aware of any reset procedures besides dis/re-connecting the negative battery cable...
@@masood-tv Hi Masood,
I replaced my amp by 2 other I bought used because it did not emit light, but after replacement the symptom still persists, no light coming out of the amp, nor the charger cd that I I have also replaced, all my fuses are good, and the current is coming to the devices ... I do not understand.
Thank you for your reply.
Hi Frederic - it sounds like you have checked everything in the trunk already...perhaps your main console is bad or the cables from it to the trunk...you may have to take it out (it is not that difficult to remove it) and do some troubleshooting there...
Masood, I was working perfectly on a CL500 I cut into a brown and red wire on a adapter that wasnt being used (16pin) an it took the whole system down. Even after putting them back together
Sorry to hear rhat...
@@masood-tv Me too! using your method the small box near the CD changer is TeleAid? the harness control something that was previously removed. My question is...what components are is the trunk Amp,Changer, Teleaid and what else?
Hi Chuck, it has been such a long time since I did that job. But, I think I do identify them in the video.
Morning Masood, I don't know how to test the FO cables.
I don't have an assistant so I tried splicing each connection shown in the video one by one. Still don't have any sound. Does this mean my amp needs to be replaced?
Hi Kevin, if you have tested the connections, then it does point to that. Try finding one you can easily return just in case....
How you fix if it says magazine empty
How did you get the tape deck to close with the audio jack hanging out? I have a similar tape/AUX thing but my tape deck won't close and will not play the (tape/AUX) while it's open
Hi Nick - just as you see in the photo. Perhaps, it depends on the thickness of your cable. I had a rather thin cable. I have a better solution for you if you want to spend just a few Dollars and go bluetooth. Here is a video I have on that: czcams.com/video/ZaBxxTxGo7s/video.html.
Tele-aid and phone box are not blinking red, are both units bad or is it just tele-aid because its the start of the loop?
Hello, think of it as a chain with links. If any link is broken, so is the chain. So, both could be bad or just one. You have to eliminate each separately. Bypass the first one in the chain and see if the second works. In your case, you could fast track and bypass both since neither is really needed.
Spliced the teleaid and now all modules except teleaid have fiber optic light. But still no sound. Any reccomendations?
Already checked the amplifier fuse and it's good
@dreamairsoft2531 if you have checked all the fuses, then you may want to source a used front unit from eBay or elsewhere with a good return policy in case the replacement is bad, or good but wrong diagnosis.
@@dreamairsoft2531 take teleaud out of the loop.
were did find the optics splic all radio shacks are close in my area
Hi Charles Davidson - please forward 18 seconds into the video to see where you can buy it and for how much...
Hello, I Folllowed instructions on your video. Now there is only amplifier and cd changer on the orange cable loop. Both show red light signal when tested. But there is message on the screen -"TELE AID ACTIVE" and no sound. And if I touch any buttons like volume, it is going in mute. This thing is driving me crazy, I cant find the problem. It is 2001 Mercedes S430. Any help is greatly appreciated.
Hi Victor - what was the original symptom? Did you have no sound whatsoever? Assuming you had no sound to begin with, did you check/replace the 20amp yellow fuse?
If yes, then I hope you purchased a couple of the Fiber Optics connectors. Why don't you bypass the CD changer as well leaving the front radio console and the amplifier as the only two devices in the loop. See if that will work for you. Otherwise, I would suspect you have a bad amplifier not knowing much more about your particular situation. Report back please.
Originally it was working, the sound was great then "TELE AID Active" sign started to appear on the screen, it was on and off, at the same time this sign appeared the sound disappeared until it became permanent condition- no sound. 20 amp fuse is good, I replaced it any way, no change. i do have fiber optics connections so i just bypassed cd changer completely. still no sound and same sign on the screen "TELE AID ACTIVE", I disconnected antenna amplifier, still no change and TEL AId Active sign is still on. Now there is only amplifier in the loop, I do have in the cassette player adapter with wire connected to my cell youtube music and still no sound. i pulled out fiber optics connection from the amplifier jack port and there is on time red light blink from amplifier.
I am sorry to hear, Victor, that you are having these issues. I know it can be frustrating. I hope you have your fuse chart still. Have you checked fuses F61 and F66?
Also, have you looked at the Roadside Assistance (wrench) and the Information (i) buttons inside the armrest? Are they lit? Press those and the SOS button in different combinations and see what happens. The armrest buttons should not be lit up. Also, have you tried changing the volume using the steering wheel up and down buttons?
If you don't have a fuse chart, let me know and I will try to find an electronic copy for you.
Please can you give me achart of fuses
I have marcedese s320 model 2002
There is no sound from radio on my s320 w220 '01. The same time, there is good sound from cassete, tv & cd. What can it be?
Hi Evgeny - if you are getting sound from your cd and cassette drives, it tells me that your fiber optics network is in a closed loop and working fine. If any one component within the network is bad, you would not have sound from any of the others. That narrows it down to your radio...I would have the radio checked first.
did you ever get this solved?
Hello Masood. I have a 2001 Mercedes S500 with Bose premium audio system that came with the car. The unit looks exactly like the one you have in the video. I would like to replace my head unit with a newer model that has Navigation, Bluetooth, touchscreen, and so on. Is there anyway I could do that without having to rewire my speakers or replacing anything else. I believe it comes with fiber optics. I would appreciate it if you could give me some advise concerning this matter.
Hi dariush, if your sound system works, why bother. Get a Bluetooth dongle instead for connection to your smart phone. Anything you install will get outdated over time. Here is a link to a video I have on how to extend your cigarette lighter outlet for easy access: czcams.com/video/7ooU9n-880o/video.html.
If I could just replace the head unit,
@dariush ashrafi you can, and there are a few 3rd party products with instructions for all the connectivity to the fiber optics network. However, none of them are turn-key.
my optic fibers have been spliced, yellow fuse is okay and red light turns on at the head unit fiber optic. i lost my audio recently and it only happens during the cold season, and yes i checked every connection and made sure it was good. any ideas?? i have a cousin that works a mercedes and he said changing the head unit to an aftermarket one should do the trick. if i do that, which stereo system works best if you know?
Hi, I would suggest you find the same head unit from a junkyard.
@@masood-tv will do that , hopefully it works because junkyard ones are left outside probably doors smashed / windows open and rain inside, hopefully i find one in good condition and by the way, how do i dispose of the old head unit? the clock on the head unit isnt the same on the dash one, maybe that can give you an idea? i have todays date and current time on my head unit but the display says another time? yeah this cold weather messes up electrical connections 😂😂
@@legodude960 you are right. Please keep us posted.
My radio sound fades in and out. Can someone please help
I have cut the the orange CD changer wire, I thought it was a normal wire/job. Now the audio system is completely dead nothing happens when I press. I have tried to look for a wire inside the orange CD changer fibre optic cable but there’s nothing in there lol it just looks like plastic. Please help. I thought I’d be able to join a new CD changer to my car wires by cutting and joining together.. Comand completely dead! (I don’t have an amp)
Eat Properly - Hi. Yes, these are Fiber Optics cables and not regular electric cables.
Masood I have cut them! How do I join them back? Fix them?
@@rikkyash2353 I haven't tried this, but theoretically you should be able to use the connector I list in the video to reconnect your cut line.
My nav CD won't go into the front slot any ideas? It was in there and in ejected it now it won't go back in
Hi Timothy - it must be due to some obstruction. I have no idea. Try looking into the slot with some sort of magnification.
How did you get the cassette to stay in my 02 s430 ejects it because of the aux cord
Hi d g, if you get the cord to stay where you see mine is, it should not eject.
Masood? Where are you located at? I have the same problem and I get message of no cd changer while my radio works perfectly, I have e430, 1999
Hi Miss Persia, I am in the UK currently.
@@masood-tv Thank you for replying to me. Masood, is the process the same for E430, 1999?
@@Empurioss - I don't think so but you may want to check and see if it looks anything like the one in the video.
@@masood-tv Thank you Masood ! I will check it out.
No sound from my radio. I watched your video. I by-passed the CD changer and connect the orange line (fiber optic directly to the amplifier. The red light on the orange cable not blinking. Please help. Khosrow
Hi Khosrow, please read my diagnostic steps at 03:15. The culprit may be your amplifier.
Thank you very much. Is it easy to test the amplifier?
@@davidfarahani1321, yes, it is not hard with a good light source abd connectors. Search CZcams and I am sure you will find instructions. Also, test your cable to the amplifier.
Masood Thanks, This morning I bought a amplifier from wrecking yard and still no sound. I have checked all the related fuses and they are fine. the amplifier could bad too. Can I test the amp? You are my only help. Thanks again, Khosrow
Hi Khosrow, how do you know the FO cables connecting the radio and the amplifier are ok? Test the cables first.
The screen usually don't work. But radio is good. Please what's problem??
Hi Nasser, I am not sure. It could be a number of things. If you have a fuse chart, check out all related fuses first. In some instances, the battery could be weak. At least your radio works :)
Where you located im having the same issue with my 2000 s500
Hi Andre, just bypass to the next good one in chain.
no touchscreen? the lexus ls400 had a huge touchscreen in 1998...
Hi V.C. - unfortunately not. Keep in mind, cars manufactured by different brands on any given year vastly differ from each other in so many respects - including features and employed technologies. There were many Mercedes Benz innovations which were not featured in other brands for many years. I am sure Lexus too must have had unique features others didn't.
05 S430 keeps giving me "system unavailable" message. Everything was fine right after I fixed the CD changer. Then when I was gonna come home from work the system gave me the message. I have to check the fiber opts. Also it drains the battery.
Hi alibaba66able - yes, check the cables. The battery drain issue is no fun but there are tons of info on the web on how to diagnose it. Good luck.
Hello and thank you for the fast reply. I did check the fiber ops this morning. The one for the telephone (Motorola one) didn't have any light coming out of it. So I went to dealership to buy a coupler. When I came out of the dealership, the radio and everything else started to work LOL. So I didn't loop our the Motorola for now. I shall let you know how things go. Thanks again.
You are welcome...perhaps, it was just a loose connection issue. Hopefully, it will keep working for a long while...
Hello, s430 2003, the optical cable is thoughtful and does not fit the sound
Hi Achi, this video applies to 2000-2002 models as you see in the title...
I had a telephone error spliced it,still nothing
Hi 865_Rostislav - sorry, I couldn't get back to you sooner. Do you have sound coming out of the speakers for the radio/cd/tape devices? Please keep in mind this video is just to troubleshoot the fiber-optics loop. You have to make sure you have power and ground also...something the video doesn't cover.
hi masood, i haven't messed with the system in the back , but when i was doing step by step with your video, the previous owners already did what you did in your video, i lose audio during the cold time, another thing that could possibly cause to lose my audio is the battery terminals. yes i know i shouldn't of messed with them but i replaced battery terminals, so far they worked okay but i think since its not the same as OEM battery terminals, i lose electricity.
before the cold weather began, i had audio , and i never lost audio, but when the cold weather began, i lost it, sometimes it plays, sometimes it doesn't. please help, idk if i could show you personally a video of how my battery terminals look like, and see if they are okay or i will have to look for a more proper terminal connections
@Владимир Новико́в HI, the ontermittent nature of your audio playing and cutting tells me that one of the fiber optics or electrical conmection points may be loose. I would check that first.
@@masood-tv hi masood, yes i checked all the cables , in total of 3 fiber optic bypass part, they are all tight and secured.
