QA1, QA2 and QA3

When performing QA1, QA2 and QA3, and all the other pinpoint tests, can I simply disconnect my PCM and test on the connector or do I need a breakout box in order for the tests to be run properly?
Thanks!
Joe

With the info you've given..... I'm at a loss....
Without year, make, model and engine... I'm left with the feeling that you're trying to look "good"... I hope I'm wrong....
PPT QA is for communications failure.... Most (if not all... if your talents permit) of it can be done without the BOB... but disconnecting the PCM is not the way to do it.
The "usual" first step on gas engines is to verify V_REF.... and it usually easiest to verify V_REF at the TPS connector - be very careful to avoid spreading or otherwise damaging any pins....
To assume that everyone on the NG has access to the PC/ED.... well, I wont comment because I will be accused of being elitist or something....
Now... it may be in your best interest to let us know what you're working on and what the problem is.... Sometimes, not all things are as they appear....

I'm no wiser...
Pinpoint test QA is for when you can't communicate with the PCM properly... not for if you have no codes in memory...
