Sync 1 to Sync 3 upgrade - Reverse camera not working

Bolter · 23 May 2025 02:19

I have a ANZ 2012 Focus ST and upgraded from Sync 1 to Sync 3 with an aftermarket harness. Everything seems to work correctly except for the reversing camera. When putting the vehicle into reverse, the screen turns blue (massage at bottom saying to check your surroundings)then black and then get a meesage stating camera unavailable please contact your dealership. My setting for the reversing camera are -

The apim is running 3.4.23188
I was told I may need to run a LIN Calibration from the tools section in Forscan. But when I go there, there is no LIN Calibration setting.

Below is all the other settings that might be needed for any hep

And I had a DTC stating -

Can anyone suggest a fix. I tried the EU and NA setting for the camera, but they didn’t work. The rear sensors beep when nearing objects, but no camera. It is an oem camera. I know this is long, but I wanted to add all that I have.

See this thread…Backup Camera Not Working After Switching from Sync 2 to Sync 3

Read @jmbach comments about the camera wiring.

Thanks for your reply. I notice that the settings for my reversing camera ends at 7d0-07-04 I do not have 7d0-08-xx can I update something to get it? (Firmware?)

Yes, update firmware to MY18.5+.

2012 Focus ST. For reference, your vehicle is C1CMA based, so settings in the APIM and other modules need to be set accordingly. Various settings refer to CGEA 1.2/C1CMA and CGEA 1.3. Where applicable you will use CGEA 1.2/C1CMA.

That’s a 2017 APIM. I would make sure the wiring is solid first before updating the APIM.

Blue screen is no video, camera is not turning on, or there is no physical connection from the camera to the APIM.
