Alfadiag keeps losing comunication?
I purchased alfadiag and a cable from Rarebear, set everything up, connected to the selespeed ecu and started to run through sensor checks etc.
The problem is, whenever I tried to calibrate or depressurise the actuator, the message would say either 'test complete' (without doing anything), or 'comunication to ecu lost'.
Following Rarebears advice, I connected alfadiag to the engine ecu and started checking a few things, but also had the same error 'comunication to ecu lost'.
However, after connecting to the engine I had another go with the selespeed ecu. This time it calibrated first time with no errors.
I tried to run some more checks, but again lost comunication.
So, yes I have the car mobile again, but still keep losing com's.
Has anyone else experienced similar problems?
