GM 6L80 TCM Possible PINOUTs

Question:

Why is the OBDSTAR DC706 6l80 pinout different than the diagram on websites including Alldata? Is this a misprint?

 

There are new types of ECU with different diagram.

Check out possible pinouts and reviews.

 

Customecm PINOUT:

Review:

1)just follow the pinout at customecm. I did and works correctly. I have OBD plug at the end, works with all the programmers and scan tools. Dont forget 120ohm resistor, and power switch on ignition power helps too

2) I made a quick one based off the customecm website and it worked fine. Cloned with DC706. Followed up with SPS just to clean up.

 

OBDSTAR PINOUT:

Review:

1)PIN1 and PIN2 works fine, same pinout from IO terminal

2) I’ve used the dc706 Pinout on the tool works great.

 

I/O Terminal PINOUT:

Review:

Before I made that adapter, I was using IO adapter, and IO has same pinout with 1 and 2 pin as OBDSTAR.

 

Done!
