[EN] Focus Mk3 (2011) quick help

I think I have found the problem but to check as I changed the 3 antennas I put recent antennas and standby with keyless entry system while my vehicle does not have this option

Not sure the antennas have to do with this since they have the same part numbers as those with keyless entry and start,it maybe related rather to the remote function actuator module part number not matching.

I put back the original rfa I reprogrammed the keys but still the same result

I'm pretty sure it's a sealing problem I also have the fuel flap it doesn't close even though I closed the car

When i scan my car with both Forscan or UCDS i have almost 45 DTC’s witch i can’t clair some are related to modifications i made in the car such as LED bulbs o
many others are due to BCM internal components failure apparently although the car is running very well.
The BCM is a very sensitive part and some a simple court to circuit could dommage it.

before I changed the bcmii I bought a bcmii starter kit engine computer key meter lock column and still the same fault code u0515

Maybe the DTC you are referring to was already in the BCM you have installed in your car,did you the parameters reset ?

yes every time I change the module I have it reset and when I disconnect the 3 antennas I have a message on the counter no key in the vehicle

I looked at the rfa connectors there is a lot of humidity

I mean parameters reset in PAT’s programming.

the pat no it asks me for the bcmii code and rfa code

You had originally DV6T-14A073-HH as BCMi part number and AV6N-19G481-AM as RFA part number(mine is AV6N-19G481-AK) for the BCMi it seems compatible although it cames from a C-Max mk2.5 (2015-2019) but the RFA part number seems totally different to what is used in both 2011-2019 Focus and C-max.

how do you know for the original references of my vehicle?vin ??
so my current bcmii does not pose a problem?
for the code you have to ask the Ford dealer?? thank you for the information

You can see that in Ford Edis,if the BCMi has been provided by a professional there is no problem but if it has been picked up from a junkyard or from eBay you have to check out at least if the donor car has Keyless start.

the bcmii comes from ford kuga 2015 logically yes with keyless start
and for the code

I need the DTC’s codes in the right order as below
DTC
DTC failure bite
DTC status bite

If the the car engine turns on and the doors close correctly with the key fob than the PAT’s programming has been done successfully now if you still have some DTC’s i could be related to the parts you have installed (software,calibrations)

I replaced all the parts as original but still the same u0515 and in ipc sometimes I have u0214

I switch on the ignition and I open the driver's door I have a message
Ford smart key switch off ignition press power

It's normal,i have the same chime (with ding dong tone) when the ignition is on and the driver's door is open.

L’alarme a l’ouverture de la portire conducteur quand le contacte est mis est tout fait normal,si la DTC persiste aprs l’effacement avec les anciens et les nouveaux modules ca ce n’est pas anormal, a pourrait venir des connecteurs du module actionneur des portires dans le hayon,le connecteur dans le BCM (mal branchs)ou des composants relis a ce dernier (antennes,serrures de coffre ou poignes si le vhicule est quip) d’ouverture sans cl,il faudrait aussi vrifier la compatibilit du logiciel de calibrage entre les modules a peut souvent dclench ce genre de dfaut.

the fault code u0515 is effective it comes back when I press the keyless start button I cut the red wire from rfa to the bcmii start button, still the same fault, no other faultnumber 3 = rfa number 17 = start button number 14 = bcmii

Have you programmed the immobilizer or only the remote open/close function ?

since rfa replacement i did smart key programming

The RFA has it the same part number and calibration ?

it's not the same because I changed the key star kit again

I have to update my autel software because I don't have this option as in the photo

I noticed the rcm has a different vin number than my vehicle

Did you replaced it ?

Yes

You need original as built.but it will change nothing for the RFA issue.

and if I try the rfa update?? with forscan

It is risky to update vital modules such as BCM,RFA ABS with Forscan however if you want to go through this don't forget to store car's profile,use a battery charger and use a full compatible adapter.
