Coding HK sound system in M4

slobo7x · 12-24-2020, 02:50 PM

Hey guys, did a full retrofit of HK sound system in my 2015. Got all the speakers and full wiring harness from a donor car, coupe as well.

I changed the VO in SALAPA to 688, removed my 676 and saved and coded FA to the car. After reading SVT values I coded the nbt_headunit with the new FA also coded asd with the new FA.

I do not see an amp ecu at all, I also am getting "no warning" tones on my display screen, no sound coming at all.

Did I miss something in coding or is the amp bad?

Thanks for any insight!

Either bad wiring or amp.

Wiring is ok, I double checked most Connectors and power to the amp as well as asd wires with K can lines.

My theory is If the amp was ok, it would show an ecu inside e-sys salapa correct?

Yes, after Read ECU you should see it.
You can try saving SVT to the car, see if that helps.

I can try, but i've already read the SVT then coded each ECU.

What is the difference in doing a save under SVT? Just trying to learn..
Thank you

Error codes in ista D are saying most ring is broken and no connection to amplifier and instrument cluster.

Is this because amp is bad and not sending a signal back to headunit and gauge cluster?

Thank you

Thank you

Bad amp or problem with MOST.

Most is fine, damn shame after all this work to find out the amp is bad. Been a great project and was extremely excited to have it completed, but now we wait..

Thanks for your help
