Reverse chimes lost after fitting amplifier
Posted: Wed Feb 26, 2020 2:13 pm
I have a new 2020.25MY RANGER RAPTOR (Aus).
I have just fitted an aftermarket amp and speakers running off the factory head unit, this set up consists of a Focal 5ch amp (FPX 5.1200 5-CH) 2 x Focal hi-Lo V2 Line Level convertors, focal speakers all round + kicker 12" sub.
I have used forscan to make the following changes to the ACM:
727-01-01 9E00-1808-9Axx (Disable ANC)
727-01-02 0000-xx (Flattern factory EQ)
The problem I'm having is that the reverse chimes are now coming through the IPC and not the audio system.
I've tried switching the chimes between audio only or IPC cluster in the IPC non asbuilt module to see if this clears the issue, but it makes no difference.
Searching on google has only lead me to find one possible causes but it's in reference to US F150's.
"The ACM has resistance sensing which tells it to send all audio notes generated by the IPC to the speakers, if there is a drop in resistance then the IPC will generate all tones, this will happen when speakers are disconnected from the factory speaker wires, or if the factory speaker wires are spliced into RCA's and connected to an amplifier input, as not enough resistance is supplied. You can defeat the speaker detection and return the chimes to your speakers using forscan, this doc includes all the required codes, https://docs.google.com/spreadsheets/d/ ... =815852466"
I'm wondering if the above would be the same for the ranger? I have tried using the spreadsheet above and changing the Front/Rear Speakers Detection enabled /disabled from 1=Front & Rear Det enabled to D=Front & Rear Det disabled but it made no difference.
Can anyone help here? Am I going down the right path?
