Hey folks,
I think I’m searching for something really specific, bacause it is being hard to find out any guidance on that.
Well, I have a Ford Focus Fastback SE 2019 (LATAM). The car came with the old Sync, with no built in functionality aside the radio and parking sensors. A very basic car, with regular A/C and all alerts displayed by the IPC.
I managed to retrofit it to a Android Headunit with a CANBUS compatible faceplate, using all stock wiring and accessories, such as park sensors. All the rest was removed - original sync Headunit, APIM module and even microphone. All stripped.
Everything is working perfectly - parking sensors, steering wheel commands, original USB outlets and so on, but a U0253(00) error code keeps popping up on RCM. After some research, I discovered that is is related to the fact that an APIM module is expected (configured) for my CAN network, being absent during self check.
That said, I’d like to know: any chance to come up with some as built flag to get rid of this configuration, toggling APIM to absent? If so, can I perform it using ForScan+Vgate iCar Pro or would be necessary to go for a UCDS?
I tried my best to find any info about changing as built config for this purpose, but no luck so far.
If needed, I have a fresh backup from Ford about my as built data.
Any guidance or help is appreciated!
I believe this is the crash signal that the RCM sends out for the emergency call. You just need to use Forscan to turn that off in the RCM.

I believe it too. The doubt in this case is: is the GWM registering the module, forcing RCM to see for it, or it is just a matter of config on RCM?
In case of RCM config, any instructions about what to disable?

Not sure what your settings are now but here is what we have in the database.

This will likely solve the issue if it is the emergency call feature. This should be equivalent to turning it off in the APIM…
