OK so I had another go and paid attention to the ECU tree this time...they were all red. So ISTA is seeing the car and filling in the vehicle details, reads the ECU's present but is unable to communicate with any of them. This is probably causing the Fault Codes (?). ISTA displays all these fault codes as shown in the post above but it won't clear them.
When I try to clear them it shows the dialogue attached telling me to turn off the ignition and remove the key but then after that it just sits there. Does nothing and the only option is Cancel, after which the Fault Codes remain.
So assuming this is all related to the version of ISTA????
If so does anyone have links to a more recent version please?
