Hello, does anyone happen to have a pinout diagram for a Sync2.5 ACM?
I retrofitted an 8" Sync 2.5 ACM (changed from a 4" Sync 2 ACM - I have no APIM) last year but the microphone doesn’t work.
Forscan shows there is a DTC in the ACM for the mic open circuit. I’ve checked out the wiring and tried a new mic and it all looks good (16k resistance measured at the ACM connector and it’s a 16k mic).
I’m wondering if the Sync2.5 ACM uses different pins for the mic but can’t find any wiring diagrams for it. If it’s not that, I guess it’s going to be either a faulty ACM or will need some AsBuilt changes.
Thanks for any help
