Zafira A 1.8 Z16XEP 5wk9157 replaced with 5wk9154

[dawid2a]

Hello, I have a vectre 1.8 125km, I replaced the 5wk9157 ecu with the 5wk9154 because I read that they are interchangeable, but from that moment the fans in the car run all the time. In the errors there is no reading of the temperature sensor. Is there any way to fix this?
