So I am finally getting ready to do a X40 ACM upgrade with my Sync3 retrofit. I installed a preMY20 APIM awhile ago (I’m not with the truck right now so I can’t verify what version it is but I do know it was a build date of 2019) and I want to get the higher SirusXM sat radio channels as well as the album art when listening to sat radio. I can’t find a K series ACM that has HD radio but I did find a few LT4T-18D818-CC, LL1T-18D818-CC, and a LS7T-19C107-CC APIM’s that I beleive will work with sync 3 retrofit APIM.
I’ve read this post:
and used the listed APIMs as for my search.
I understand that I will still need to add the 2-4 wires but the question I have is all these ACM that I have found have the A2B (blue connector) on the back. My system is factory Sony system. Can I use ForScan to “not use” the blue connector and will it still work?
I dont think there is a K series ACM that has x40 without A2B. The Ranger and Maverick in 22 I belive got X40 without A2B. If my memory serves me correctly.
so I found an ACM out of a Ford Fusion LS7T-19C107-CC build date Oct 2019 that has HD radio, x40 and a CD player to replace my existing ACM (w/CD player). Once it gets in I’ll wire it up and see if it works.
So I installed the above ACM, made the wire connections for:
APIM pin 27 to ACM pin 5
APIM PIN 28 to ACM pin 4
The rest of the wiring was already correct. Also made the AB changes to the APIM and ACM. However, the system audio won’t turn on. I press the on/off on both the FCIM and on the screen and it does nothing. I reinstalled the original ACM and it powers up just fine. Is this indicating a bad ACM or am I missing something?
Also, I made sure to set A2B to 0 or 1 to disable per this:
727-01-01 xxxx Xxxx xxxx
A2B must be enabled for B&O or Revel audio systems.
As for the ACM they always have power to them but turned on through the Canbus. The wires you added are great but those only work for the Sirius x409 stuff.
We would need to know what the L series ACM came out of and also check the Pin outs on it for C240A & C240B. Some of the pin outs did change starting in 2018. Honestly with A2B though I dont think your going to get it to work unless you put in the right AMP and cable/wiring.
I see it was a Fusion and a 2020. I am pretty sure the PINs are a bit differnet.
Yeah the listing says it came out of a 2020 Fusion.
I’d have to pull up the wiring diagrams for a 2013 and compare it to the 2020. I suspect that you might be right on all aspects and it’ll be more trouble to rewire it. I would have thought that the Canbus wires would be the same, but i don’t know.
If the LR3T-19C107-FF (doesn’t have the A2B connector) wasn’t so expensive I’d get one of those to test out.
They usually are. If I remember the 2013 is CEGA 1.2 and the IPC sends the signal over the ICAN bus. Double check the ICAN wiring to the ACM and the IPC.
Thinking outloud here. I know it is called HS3 on the CEGA 1.3 networks that the Fusion would have been on but they should be the same 2 pins on C240A.
so I looked over the wiring diagram for both a 2013 setup and 2020 setup. The Can lines are on the same pins. The only exception that I could see is that on the 2013 its on the MS CAN. On the 2020 its on the HS CAN.
I don’t know if that’s enough to not make it “turn on”. If it is, it doesn’t explain why other ACM of that same year without the HD radio work when people make this mod for the X40. Maybe its only applicable to the L series ACM?
Thats HS3 which was the ICAN. I did not see MSCan to the ACM. I will look again in case I missed it. As long as ICAN/HS3 is there it should get the signal. Check the harness to make sure those are being pulled from the right spot. It might be good on C240A but where it’s getting the signal from might be bad.
There have been several documented instances where these prebought harnesses were wired wrong.
I’m on the factory harness. The old ACM will turn on so I know its getting the signal from either the APIM or the FCIM physical button.
I’m sorry, I stand corrected its pin 14 & 15 for iCAN on the ACM on the 2013. Its pin 14 & 15 for HS3 CAN on the 2020. Coincidently, I checked a 2019 F150 that would use a K series ACM and it has the same HS3 CAN on the same pins.
Everything is leading to me believing that this is a bad ACM unit.
