Hi ,i have a strange problem that came up with a ford fiesta gasoline 1.4.
Ecu sim21 ori gets water and damaged, get a scrap ecu with forscan maried to car and started.
Problem is if i left car some hours didnt start and get message for less keys programmed to car and ecu didnt give positive feedback to pats.
If add the key and ecu to pats car starts for some hours. Try with ori eeprom,same.'

What will be the cause to this ,i am stuck...
The faults i get is B2139 ,B1213, P0603.

Need help , thanks.

u cloned ecu or just programed used ecu ??
1.bad voltage can get ecu data corrupted
2. tools used not ori (happend before with VAG component protection for example)
3. if u cloned ecus, posbile data was corrupted.

To start, full information about the vehicle would help a long way, such as inclusion of year. Also, do you have the part number and calibration for original and donor? Did you clone or reprogram, and are you doing this process entirely with ForScan?

Cloned eeprom ,ecu is same numbers ,also try with ori eeprom on , same. Car accepts the key and pcm module add to pats and starts without faults, If left car some hours lost sync and a key. Power and grounds checked.
My tools is genuine.

Solved ,even ecu are same numbers needed tranfer and flash ,not only eeprom or just add keys and ecu with forscan.

Thanks for help!
