|
|
Auxiliary Heater (Entertainment Bus):
521#0100000000000000 On
521#1A00000000000000 Off
These codes need some additional testing, but seem to work
Did anyone find out what bytes 2,3,4,5,6,7,8 could mean ?
Example:
521#0100000000006A20 On
521#1A00000400FA6E28 Off

Great! the details of the 521h seem to work. The byte 7 temperature calculation also results in correct cooling water temps.

My understanding of the German language is not so good: does the XLSX file contain ID and byte info on the J386/J387 Door Control Units (connected to the Convenience Can-Bus) ?
Found these codes on this forum, but my car doesn't respond to them:
// Front Left Glass Up
181#0200
// Front Left Glass Down
181#0800
// Front Right Glass Up
181#2000
// Front Right Glass Down
181#8000
This weekend i am going to try to sniff the codes for controlling the windows. Will report back when found 
Regards,
Chris

Hi,
just size the column header line in the sheet bigger and you can see the English descriptions of the columns.
Best regards, Rainer

Did you succeed in enabling the headlights on MQB platform?
When i send the following codes (sniffed) then the headlights flash once every time i send it. If i remove one of the two codes, nothing happens.
3C0#74000300
658#0070040000000200
It seems there is some other module which repeats other commands, resulting in my codes only making the headlights flash very shortly like a photo-flash (they are LED headlights).
Also i have tried to enable the headlights using VCDS plug from RossTech, but i can't seem to find the option to enable the headlights through OBD. The idea was to sniff the codes from the VCDS plug and use them to enable headlights.

Chris |

In more clever cars, like Passat B8, Golf VII, steering wheel ECU is communicating with BCM over CAN. So you can control blinkers, high beam.. But you should keep correct timing, counter and check sum.
For enabling headlights with VCDS you can try this:
Goto BCM module;
Output test;
Choose light which you need
Press start
Check CAN bus and you will see how easy you can control this.
BUT! It works only with ignition.
P.S.: In output tests you can find more interesting stuff, not only lights

Daytime running lights can be switched off using this output test.

Sniffed the bus while executing output test, and filtered it.
Log is attached. Next step: interpret the commands

I would propose to do printouts of the Message Changes View in KCANMonitor and to put the paper sheets over each other.
One sheet printed with Auxiliary Heater on and one with off.
You should see which bytes are different and be able to concentrate your work on them.
Best regards, Rainer

Its quite easy
If i good remember...
0x700 - keep session alive
0x70E - tested ID
0x778 - BCM ID.
Output control is working with command 0x2F.
So basicaly you need send periodic message, open diagnostic session and control output. Check log files, analyse what each CAN msg does and you will understand how easy its..
But as i said - it works only if ignition in on..
More about message structure and etc you can find in google: ISO14429. Or simply UDS diagnostic.
Short info about commands:
