Can I get the code from a J519 - Onboard Supply Control Unit

[hillburnsh]

First post asking for help (read a ton from the site) so excuse me if it's in the wrong place or if I don't provide enough info initially. Although, I don't think I'll need to provide a bunch of info other than my question.
2011, VW CC, ENGINE CODE: CBFA, 2.0T

It's had an electrical issue for 3 years (sitting in my shop). I have "NO COMMUNICATION" with any module. I've sent the ECU to reputable company for diagnosis. They returned it, said nothing wrong with it. I've replaced the gateway (J533) and coded it correctly. I've used my oscilloscope and either get nothing or scribble. I've also tested the canbus (all 3) networks with a DVM and those voltages are no where near what they should be. I can give them but don't feel it's pertinent yet.
I'm pretty convinced my Onboard Supply Control Unit took a dump. I've ordered a replacement one (correct part number) and figured I would get the codes off my current J519 while waiting for the replacement.
However, I feel like I've tried every way possible to connect my breakout box w/ECU connection (same way I got the codes from the ECU, J533, and a couple other modules. But no matter how many powers & grounds I connect to every , it won't communicate with the VCDS. How else am I supposed to get the codes in a "no comms" situation?
I know I have to connect the CanH and CanL in connector spot 'G'. Which 12v (30), 12v (15), and Grounds do I need to connect and in which connector spot? All spots A-L (except 'H' - N/A)?
Or am I screwed?

Some modules need to receive a "wake up" code before they will communicate, this may be the case with the J519 - maybe someone can clarify?

You might get asked to post the VIN so experts can retrieve the setup of your CC?

 

[hillburnsh]

Just in case, here's the VIN: WVWMP7AN2BE714377

 

[hillburnsh]

Anyone?

You have a scope yet you measure CAN with a DVM - Strange choice of instrument !!

That implies you have Communication with J533 Gateway ??

Really, not pertinent now ??

when will you divulge them ? After you have fixed it ?? - See how silly that is - Or am the idiot here ??

Please can we have voltages please ?


Let's see an Autoscan ?

@hillburnsh I can pull the correct coding for a small fee.

I really don't care for sarcasm at this point. But inquiring minds wanna know, is there something wrong with checking measurements using 2 different tools (ie DVM and oscilloscope)?
And the question was "can I hook up the J519 to VCDS with an ECU pin out adapter on my breakout box in order to get the codes for programming?". That does not requires a voltage reading or a sarcastic comment of my check procedures to answer it?

I'm not implying I can communicate with the gateway, I'm stating I can communicate with the gateway (off the car/bench test) with VCDS through my breakout box with the ECU adapter.

But since I'm here "asking" and you countered with you're question. Maybe you can divulge which voltages you want? And from where? J533 or J519? That's pertinent.

Thanks

Let me ask you a different question that I thought on going to sleep. I'm beginning to believe my ECU connectors (T94 & T60) are not pinned right.

I have an FSM and another workshop manual that is "supposedly" VIN specific. With both of those manuals, the pin outs of the ECU are not even close.

I have wired the ECU out 3 times now, according to each manual and neither time seems to improve my situation. I no longer care about wire color coding as I know exactly where each wire goes to the car (exactly) from ECU location.

Is there any way to get the correct ECU pin out for my VIN?

Auto scan?? You seriously need me to post a picture of a "no communication" with anything?

Thanks

Would be good to see what the Can Networks look like on a scope at the Gateway !!

Not a picture - A Scan please !!

Ok, how do I show you what the can networks look like via my oscilloscope?

As far as an auto scan, it won't communicate with the gateway. You want me to attach that scan?

I'm now leaning towards my ECU is not pinned out correctly. Even though I've done so via the fsm and workshop manual(VIN specific). I have also traced each individual wire at the ECU to it's said location. But think my manuals are wrong. I've compared the ECU pin out from the FSM, workshop manual, and all data......none of them are remotely close to each other (even though alldata is also supposedly VIN specific).

Yes I do !!

And then please tell me how you replaced J533 and Coded it Correctly ????

Why have you not nailed your self to the DLC and J533 and the wiring in between ??

I've sent the ECU to reputable company for diagnosis. They returned it, said nothing wrong with it.

Why would you be doing anything other than getting comms with J533 ???

The Mind really boggles

 

[Dr Sheldon]

Your J533 has a 20 pin connector

Pin 9 or/br > DLC 14
Pin 19 or/bl > DLC 6

Pin 1 rt/ws > SB24 Fuse
Pin 11 Br > Ground

Pin 14 > Sc7 Fuse


I now would depin or cut every wire other than the 5 above - Confirm the Powers and grounds - Confirm the DLC wires are not contaminated and then look to communicate with scan tool !!


Pin 2 Lin Bus > Analogue Clock and others

Then below are the Can Network pairs
Pin 15
Pin 5

Pin 16
Pin 6

Pin 8
Pin 18

 

[hillburnsh]

Do you think I'm new?! I've done all that and then some!
I replaced the J533 by ordering a correct part number, then connecting the original to VCDS through my breakout box with ECU adapter (said that originally). I can talk to the j533 if it's disconnected from car and placed on my bench. I copied the original code and installation list and coded the replacement with that information. Make sense?
BTW:
Pin 1 (red/wht) goes to fuse SB15 (e box low) and NOT SB24.

So I will try what you mentioned , j533 connector, I'll depin all wires except the 5 you memtioned and let you know what happens.

 

[hillburnsh]

I get the same message I've gotten before asking for help ...
"Function not supported by gateway"
I've also tried it with original J533 to validate it's not a code problem, and I get the same message.

 

[hillburnsh]

And don't know if it matters, but you mentioned a pin#2 for Lin......there is no pin#2 in this car at the J533.
