Man, I can't understand why the GM local dealer's mechanics have not used this TECH2 feature !!! The Manual booklet is missing!!!
I have problems with the oxigen sensors or the injectors or the spark plugs, without DTCs. I want to scan the PCM and get all the data printed or backed up in a CD and show this info to someone in this forum with enough knowledge to make a right diagnosis about my car problems.
I already identify the several TECH2 comm ports ( RS 232 specially) but the Service Manager is out of town and he has locked the adapter/cable connectors in his office, somewere there.
So, additional information will be welcome...
Thanks a lot in advance
