Loss of Comminucations

I just re-read post https://www.yourcobalt.com/forums/pro...ion-tcm-2.html
And must say Thanks again for the color schematics.

This answers many guestions
I see in figure 14
Tan/Blk ......= +high speed GM Lan
Tan....... .....= - high speed GM Lan
DkGreen.....= low speed GM lan

It says why many issues are caused by poor connections at the BCM connectors.

Thanks again @Coby7
