Well it doesn't matter now. I spliced the rear speakers back in for now after realizing I lost the rear parking aid tones by disconnecting the rear speakers. So they are reconnected and I just adjusted the fader slightly forward until I couldn't hear the music coming from the rear spoeakers any...
2026 XLT 2.0 EB non B&O.
Just installed the 10” Kicker Hideaway behind the rear seat. I’m using the DC offset signal sense for turn on. I have the high level inputs connected to the rear speaker wires but I disconnected the rear speakers when I did this as I don’t want to use them. I did set...
Don’t waste your time. This one was totally my fault and unrelated to disabling start/stop. Lesson learned: keep your speaker wiring away from other vehicle harnesses.
I was able to squeeze the crossover into the little open area in the left front corner near the tweeter. Cut out all the excess wire between the crossover and the tweeter. Took another short drive, all good no more beep.
Glad this ended up being unrelated to Forscan mod.
Found the culprit!
The beep was being induced into the wiring of the tweeters in the Kicker components I also recently installed🤦‍♂️. Space is tight on that side so I had run the crossover down below. Disconnected the tweeter temporarily and the beep is gone! What a relief! Now I just have to...
OK here's a short video I took this morning with 4 examples of the beep. Recording was made with phone laying in front of the instrument panel cluster. That will give you an idea of how faint it is. When I have the radio on at normal volume I can't hear it unless there's a quiet part in the music.
Brand new 2026 EB AWD. No clunk but I have noticed a faint beep from behind the dash at the speeds the AWD is engaging or disengaging.
12-13mph on deceleration, 17-18mph on acceleration. Goes away completely in sport or slippery modes.
OK so this confirms that the beep I am hearing is occurring when the AWD system engages or disengages. Now the question is why am I able to hear it? I'm starting to doubt that this has anything to do with the Forscan auto start stop disable and was likely there all along. I will try to get a...
FWIW, here's what Gemini has to say about the beep:
The exact speeds you noted align perfectly with the mechanical operation thresholds of your Intelligent AWD system:
The 12, 17, and 25 MPH Transition Logic
0 to 17 mph Acceleration: When pulling away from a complete stop, the Maverick...
Sad_Mav,
It was your instructions I printed out and followed when I did the mod. Very detailed and helpful! I am using an OHP ELMconfig wired OBD2 adapter that I bought back in 2018 to do some mods on my 2018 Ford Flex. It has a switch on the adapter that switches it from HS-CAN to MS-CAN. I...
Decided to revert the PSCM auto start stop back to factory setting until I can find more info on this beeping. While I was in there I looked at the DTC codes and there were two present in the IPMA. Maybe related, maybe not.
No the button has no affect on the beeps. Also tried HVAC off and radio off. No change. Only thing that stopped it was sport mode or ice/slippery mode. It seems like some module behind the dash is not happy that stop/start has been disabled.
2026 XLT Ecoboost
I disabled auto start stop with Forscan using the EZ mode in the PSCM. This worked however I started to notice a weird issue afterwards.
I am at times hearing a faint beep from behind the dash. It is not coming through the speakers, there are no indications on the displays when...
