Customer: replied 1 year ago.
please !!!!!!
Expert:  Wayne replied 1 year ago.

Thank you for that

does it run, what problems or functions are you missing

Customer: replied 1 year ago.
It starts and the lift functions work , when you put it into gear it says truck disabled and all the functions work but no forward or reverse
Expert:  Wayne replied 1 year ago.

Thank you for that

Go back and check the plug for bent pins

and misaligned,

what was the other lift truck doing that you

switched out ECM

sorry for all the questions, but need to narrow this down


Customer: replied 1 year ago.
The other lift we had was not working at all so we were using the computer from this machine which was working fine before we took out the Ecu, to rule out a Ecu problem
Customer: replied 1 year ago.
Is there any sequence that I should be doing to relearn the ecu back to the machine?
Customer: replied 1 year ago.
I checked plugs and wiring no issues there
Expert:  Wayne replied 1 year ago.

Hi Thank you for that

Yes that was going to be my next answer

Any time the computer is removed from the machine,

it needs to re-learn, especially when plug into another machine

You will need the software, and password *****

only available thru your Yale dealer

Which in most cases 98% of the time they won't give it to you

they want the service call

I hope this helped you
