2015 (9th gen) Honda Accord EX-L V6 Issues

dudu-lai

This car does not have a radio antenna.
There is no RCA connector in the 12P connector for the left/right radio audio output? Look for it, find it and connect it to the left/right audio input of the DUDU device A connector!

dudu-lai I am not seeing an option for "Turn Subwoofer On" - could you please tell me where it is?

Little update on item 4 (km instead of mi) -- I have made the change here, but my top screen still shows km which is why I think it's programmed in the TFT box.

EQ setup - no subwoofer option?

adnguyen23

dudu-lai I tried all these settings from these screenshots, but nothing affected the subwoofer.

dudu-lai

adnguyen23 This is the subwoofer output setting. If there is no sound, check that the subwoofer is working and that the wiring harness is correct.

dudu-lai I plugged the OEM head unit back in and confirmed the subwoofer works. I placed my hand on it and could feel the vibrations. When I put the Dudu7 back in the subwoofer stopped working (no vibrations).

Here is the 12-pin connector you mentioned

When I was plugging the Dudu7 back in I noticed one of the cables has multiple wires coming from the car, but only 3 going to the Dudu7

Finally I did some testing for the unused cables...

When I unplugged the big grey one it removed power from the OEM head unit.
When I had the radio on I unplugged the small grey one and lost signal. Plugging it back in restored FM radio.
The green cable might be the OEM microphone, but I didn't test a phone call because it doesn't matter.

adnguyen23 Verify that pins PA3 and PA9, PA4 and PA10 in the figure are subwoofer audio

adnguyen23

Hopefully these wiring diagrams help. I am still trying to locate the subwoofer wire.

dudu-lai the 12 pin connector goes to the Canbus decoder

adnguyen23

I plugged the OEM head unit and can confirm this 8 pin connector goes to the subwoofer. The pins look correct on the Dudu harness so I am unsure what's causing a signal issue.

dudu-lai

adnguyen23 You're right, I got confused. 12P is radio audio. Does the radio have sound now?

dudu-lai

adnguyen23

Is there 5V at PIN4 and where is the PIN8 cable connected?
Will I get sound when I connect the subwoofer RCA connector to the left front audio output on Zone A?

adnguyen23

dudu-lai the radio does not work. Please see a previous post where I mentioned one of the unused cables good to the radio antenna.

dudu-lai

adnguyen23 Did you do that? Play the stock radio in this app

adnguyen23

dudu-lai I plugged the subwoofer RCA into the left/right front/rear and nothing changed. Getting the subwoofer working is my #1 priority at this point.

The radio app does not do anything. This unused connector is what goes to the radio antenna.

Also whenever I go into the AUX application it shows my right turn camera. Is that normal? I plugged my phone into the car's aux port and I cannot hear anything.

adnguyen23

dudu-lai I do not get 5V from any of these pins while the car is on and music is playing. I confirmed my car battery shows 12.46V when the car is off and 14.29V when on so I know the multimeter works.

dudu-lai

adnguyen23 Please record a video demonstrating how the radio is operated.
The AUX app shows the right camera, which is normal

adnguyen23

dudu-lai https://photos.app.goo.gl/5vaGfVUsfegCuvbA7 here are videos of both radio apps.

Also I have not checked Pin 4 of the 8-pin connector yet because I do not have a multimeter.

You can purchase an external antenna to use with the DUDU radio

adnguyen23

dudu-lai Thanks, where would this plug in?

I will try to pick up a multimeter today for the subwoofer.
