Semi canned response here... any give control module to talk, must have Holy Trinity:

Verify powers/grounds/data are good. What I suspect might be happening is the ECM Power Supply Relay (J271) is the root issue... could be a bad relay itself, of the control of the relay.

The J271 powers up several different fuses in the SB fuse block, including SB2 which powers up the ECM itself.

Next time the issue happens, pull out the J271 relay and wrap some wire around the 2 large fat lets of it to short them together, then put back into socket... then see if ECM talks.

As for the coolant fan, this is normal. The coolant fans use a data signal from the ECM to operate at [X] speed. If there is no signal from the ECM, the fan module fails to high speed fans because you can't overcool the engine. So don't worry about the fans, they are doing what they are designed to do with no ECM signal.

Adding to Jef's suggestions, this page contains photos of a Red/Black traced power wire that corroded with regularity:

01314 - Ross-Tech Wiki

wiki.ross-tech.com

Scratch that. I thought this was a Mk5 rather than a 6. That exact terminal/wire may not apply so check your wiring diagrams rather than using the Wiki reference.

 

[Jef]

...... yeah, I was thinking the same thing until I saw this was a 2012. That was the 2007 Jetta with the salt water injection 330mm down the wire from the ECM....

Ok here what i came up with check powers and grounds at ECM all ok, check can wire T94/67 orange/brown(low) = 2.5v
can line T94/68 ORANGE/BLACK(high) = 11.0 VOLTS.so no i guess track down why is there 11 volts on can high.is there an easy way to divide

 

[Dana]

Hmm, shorted Powertrain CAN issues aren't common on this body. Shorted/malfunctioning Comfort CAN isn't unheard of when natural problems exist in the doors but based on the faults it looks like this is a crash repair. Are all of those Igniters with fault codes blown currently? Are there any seats in the car? Can you tell where the direct damage occurred?

I suspect that history may lead you directly to the cause of this problem. If not, I would start by unplugging all unnecessary PT CAN modules from the car to see if the Engine communication or 11V reading changes. I would start with the Airbag controller (due to the crash-like DTCs) followed by the TCM if necessary. Eliminating 01, 09, 17, etc will cause communication/Immo problems so unplugging those would be my last resort.

 

[Jef]

??? So powertrain CAN is all the same... I would expect TCM and ABS module to also be dead as well if there is 11V across one of the Bus lines.

 

[carguy]

You right go back and I was on t94/70, not t94/68.So double-check again this morning to make sure on right pins 67 and 68 have the correct voltage . I also unplug the airbag module and left it unplugged.it crank and ran one time this morning when it was cold.so I have made sure I have powers and grounds ad no voltage drop hate to pull the trigger and say it needs a computer any other thoughts thanks.

 

[Jef]

J271 relay and its wiring?
