vems cooling fan issue

[murat]

hi everyone, I hava motronic55 vems unit. plugged working on the car for two days. The cooling fan is not working.

I am not sure if it was working with motronic. I found a coolant setting in vems but it is disabled. Is it Ecu that cntrols the fan or is it fan switch itself?

I am not sure where to start from

The ecu does not trigger the fan in vems or motronics so this is not ecu related. Check your relays and sensors are ok

Thanks, I will check...
