Sorry to bring up this thread.
My situation is, I tried to download from the ecu to my laptop and error prompt shows. It shows multiply prompts just like internet ads spams n smanager hanged.
Used laptop's task manager to forced shut down smanager.
Tried few times n same thing happened again n again ...

I've pulled out the socket of the IACV while engine is still running, so the CEL came on. Plugged the socket back to the IACV and the CEL went off. Problem is, I do not have a laptop and my tuner is away. If I do not clear away the error code/DTC/trouble code, will it affect anything?
