FOCUS C MAX 1,6 eeprom corupted ,with keyless

[vijelie73]

Hello, these Fords with P1603 make me a bit desperate, what to do. I have a C max but with Keyless, the pairing procedure is the same as with these, simple or is it more complicated? Can it also be done with FORSCAN? Thank you

Hello. When i have this problem i change the ECU or i write eprom from another ECU and after this i make ECU pairing. As i remember i think the procedure is similar but the keys are not in HEC but in RKE or RFA, and that's why you nedd to pair ECU with RKE i think. Anyway is simple with FOrscan or Fomoco

Thanks for the advice, I will read the ecu tomorrow and post the dump, the keys are in RKE, but there are keys in HEC and PCM, so PCM has no outcode

hello

Do you have eprom? What ecu code do you have. I posted some full bdm files for Ford Focus, Cmax

hello, I managed to read the dump from IN and PCM, I specify that there are 2 keys written in the IC and the PCM has no outcode, when I turn on the ignition the light goes out and when I turn on the starter it starts flashing and then it generates P1603
