Ford Focus flexifuel mk1 2004. No start,  no crank
b1342 ecu is defective (eeprom in pcm is not working — replace pcm
b1601 Unprogrammed encoded ignition key detecte
Key still has its rfid according to locksmith. Only have this one Key. Anyone knows if I can 1)order a new Key , 2) erase all keys in Forscan , 3) add my two keys?

Or perhaps order a used ECU with keys and antenna and swap? Dont have much money 😞

You need to use the licensed version of FORScan and a vLinker FS cable connected to a Windows Laptop. You will be able to reprogramme the vehicle to recognise your key(s)

I really appreciate your answer, thank you unofix. I have the licensed version of Forscan on trial another two months. Regarding the reader I have this elm327: https://www.runns.se/felkodslasare/felkodslasare-ford/felkodslasare-forscan-elm-327-usb

Is it necessary to use vLinker FS, perhaps I can give it a try with the elm327 first? 

 

On a 2004 vehicle the ELM327 may still work. You can always give it a try.

I can give it a try, however the b1342 code makes me think that the ECU is defective

I didn't think FORScan supported MK1 Focus????

Also have the same issue with my mk1, Exact same codes as well (1342 & 1601) i have issues with PATS and general running sometimes

I'm looking at swapping the PCM so i'll let you know if that works out fine.

Let me know if you find a solution in the meantime.

funderar jag på att byta PCM så jag ska låta dig veta om det fungerar bra.

Låt mig veta om du hittar en lösning under tiden.

I'm thinking of buying an old cheap ECU/PCM and just swap it and hope for the best. 😅
