XZBMW  Combox retrofit keeps calling emergency services
Hi all

Hoping somebody can help me

I installed a combox telematic into my car this evening with a diy retrofit harness

Whenever I connect the battery the sos button in the car turns green and dials the emergency services.

As wasting emergency services time is something I really do not want to do again I need to work out why its doing this before trying again.

Does anybody have any suggestions?

I refitted the TCU and MULF2 into the car again and all is working as it should.

Also can I just remove the SOS pins and use it as a combox media as I don't really care about the SOS features in the car

Hey, I've retrofitted also the Combox and replaced mulf2 and TCU. The funny thing is, that my SOS-Feature is not working and I wish it would be.

Back to the Topic: Occurs the problem after coding the VO in CAS and NFRM or before you did so?
Do you really her the people on the emergency-line or is there just a message in the cic?

No I can't even code the car as it is the moment the battery is reconnected I am hearing a voice asking what emergency services I need, I disconnected the battery and reconnected it and it was a female voice the second time round so it is definitely connecting me to somebody in a call centre.

Hi,

I have no pinout available here, but it seems, that the SOS button is the issue.
So, check your selfmade adapter or wiring again.

RE: Combox retrofit keeps calling emergency services
Hi All,

I managed to get the problem solved smile thanks for your help.

There was the tiniest knick in the wires between the led and the SOS button which was causing a short.


Rewired and fully insulated the problem is now gone smile
