Hello everyone,

I have an F34 (series 3 GT) 320D from 2013 in which the surround view system no longer works.
When I trigger reverse, the screen does not display the cameras (not even the rear camera) also when I activate the PDC, no camera (no blue or nothing but the vehicle in 3D and the radars that work always.

Also, the buttons on the left of the screen (which allows you to configure the cameras ...) are grayed out.

Edit : I forgot to indicate that before they were "dead" they started by working once every 6-8 times ... but not it's been 5-6 months since the last time they worked


I attached some photos.

PS: I have a carly which does not detect the TRSVC module and when I unplug the TRSVC module the representation during the reverse is no longer the same, it detects that there are no cameras

This is my first post, so go easy on me

I think the TRSVC is broken.
You need a new / used one which has to be coded afterwards (does not work with Carly/Bimmercode).

How can I be sure that the TRSVC is really broken?

Unfortunately, your equipment is not sufficient for this.
You would need E-Sys or ISTA to check some things.
However, since I read from 2 other users in the last month whose TRSVC was also defective and it is also no longer recognized by you in Carly, I assume that it is also defective.

But one thing still occurred to me.
You can check the fuse 154 in the trunk.

So, just did that and here is the view it gives without the fuse

and with the fuse :

Can it be just a dead camera ? I just want to be sure before buying another one.

Also, how can get E-sys ou ISTA ?

Yes, it could also be a dead camera.
You can make the same test with it by pulling the plug from the camera and see what happens.

Here you can get ISTA
https://mega.nz/folder/VaJkRaLL#OlAAZdpSKjr_vcqnOR3QVw
Here you can get E-Sys + Token
https://mega.nz/folder/kO5UBARQ#yQAbNHB08TFsHw8t2Zr1VA

For both programs you still need an ENET/OBD2 cable.

So, I pulled the cameras from the module but no result.
If a camera is dead, does it "kill" the other cameras ? I mean I should at least get one working, also before this all started, the cameras were working sometimes (not often) until they went completely out.
Thanks for the links I just downloaded Esys and now im waiting for the ISTA. Do I need both softwares ? and with those softwares can I detect if a camera is not working or a module is not working ?

What is the name of the cable (serial number) of the cameras ?
Also, just ordered the OBD2/ENT cable from amazon.

I have so many questions, just bear with me please.

If one camera is dead, it doesn't kill the other cameras.
I think the other cameras should still show a picture.
But if you see no picture from any camera I am even more certain that the problem is on the TRSVC control unit because all cameras are connected there.
First you only need E-Sys to see if the program can still find the TRSVC.
If it is not visible there, then it is probably defective.
But if the TRSVC is visible in E-Sys, then you still need ISTA to find out the problem.

First I would like to thank you for your time.

Also, I've changed the 61 12 9 308 294 and 61 14 9 356 158 because the cable was faulty due to water and it was impossible to start the car... (btw it was the last time the cameras worked were like 5days before we changed the cable) so I don't know if that's related.

About the module, I found that the one I have is no longer in production (66 53 9 302 258 )bmwfans source
Can you tell me which one to buy from eBay (I will buy a used one)? I will return it if it doesn't work.

In the meantime I'm waiting for the OBD2/ENET cable (supposed to arrive on June 5.

These are the part numbers for the TRSVC which is for your car.

66539302258
66539350997
66539393952
66536994554

The module can also be from 3/4/5/6/7 F-series car.
You just have to be careful that it has 5 + 1 connections and not 1 + 1.
And yes, you can buy a used one.
On Ebay search only for the last 7 digits (6994554 instead of 66536994554).

I've ordered the 6994554 yesterday from eBay.
All I have to do now, is wait for the module and the OBD2/ENET cable.

Thanks again atzebmw, I will keep you posted once I receive them.

So, today I received the ENET cable and did a diagnostic to the car with old TRSVC plugged in (since I haven't yet received the new one) and surprise: ITS GREEN

see the attached pictures, with and without the TRSVC and the fault memory before and after resetting it.

It's my first time using ISTA+, sorry if I didn't things like I'm supposed to (I don't know how)

Let me guess. The cameras are working now again?
I think the TRSVC will fail again soon.

Well no, the cameras aren't working.
Even if the TRSVC is green the cameras are down (and that's what makes me crazy) I was hoping it's just the TRSVC

[atzebmw]

Ah damn.
What about the other error messages?
Couldn't they be deleted?
Is the parking assistant still working?

The parking assistant is still working, the other errors are still there.
Honestly, can I go further in my diagnosis? is there something else to do ? I think it's some cable but I can't really tell.

I still think the TRSVC is not OK.
You can make some tests for the TRSVC.
At the ecu tree mark the TRSVC and at the bottom "call up ecu-functions" or similar.

Or you can also view the explanation or possible troubleshooting in the error memory list.
Therefore mark the error and see the buttons at the bottom.
At the moment i don't know the description of the buttons, but you will see.

So, today I tried the "call up ecu functions" and I got this error when tried to do "tests image" (see the attached picture)
Can it be the ECU even if it's marked green ?

Does this message come at alle test functions of the TRSVC?
Then yes, like is said i think it is defective.
It is unusual that it is still displayed in green in the control unit tree, but the errors and problems already indicate a defect.

I got this message when I tried the "Test images" under "Component Triggering" under "Call ECU functions"

So, today I received the new (used) TRSVC unit and IT WORKED
YES IT WORKED

I have some errors, do I have to code the new unit ? or can I just forget about it ?

Yes, the TRSVC has to be coded.
Some things may not work (yet).
Start E-Sys and make the connection.
Read FA and activate it.
On the right side Read (Ecu).
And the rest see my picture.
