ECU Check Engine Warning

Black Stealth Down - 2009/04/20. My clutch had slipped a few times over the past few months, with very hard shaking when the cluth slipped. On the last day it slipped a bunch of times and I could feel that there was only a hair left on it, this was also the first time I had used my A/C.
This was when my Check Engine warning displayed.
I feel like the problem occurred as a result of this hard shaking or the electrical load of the A/C.

I have a digital voltmeter, so I did tests at the ECU Diagnostic Terminal.

Online, I found two images of what the terminal should look like. This is the configuration...

However, my terminal looks like this, #7 is in a different position...

I set my meter to the 20 Volt DC range, and grounded to pin #12. The reading for each pin was as follows:
------------------------------------------------------------

1 ECM - MPI Fast 10V Sweeps
2 unused N/A
3 ESC (Elec. Ctrl. Suspension) 0 (±0.01V)
4 ABS (Anti-Lock Brake) No Reading
5 Cruise Ctrl. 0 (±0.05V)
6 ELC (Automatic Trans. ??) N/A
7 A/C (Air Conditioning) 0 (±0.04V)
8 SRS (Air Bag) 0 (±0.01V)
9 ETACS (Alarm) Static on 0.74V
10 Query ECS, ABS, ECM, A/T, AC Static on 4.45V
11 Speed Sensor Static on 4.97V
12 Ground  

Here are the diagnostic codes (click image to enlarge):

I initially thought I was getting a Replace ECU code from pin #1.

I drove the car twice, after the Check Engine light displayed, with no problem. However, the next day, I tried to start the engine again and I heard some ugly knocking from the motor , so I shut her down immediately (I probably heard about 10 to 20 knocks).

I decided to pull the ECU to look for obvious damage on the board, so I disconnected the battery, removed the ECU, and visually inspected the board (an Av-Pro refurb.).
There was no obvious damage, no leaking capacitors or other burns or odors.

I reinstalled the ECU and metered the diagnostic terminal again. Same results as the first time. My new interpretation is that I was getting Code #1 on pins 9, 10, & 11, but really, I have no idea what I'm looking at.
