Citroen c2 can stream

V3 SOFTWARE
1

Have a Citroen c2 with vw 1.8t and Dsg running emu black on v3!

having issues with the c2 can stream

Multitude of lights on the dash. If I emulate paddle shifters the power steering goes heavy

anyone have anything I can look at to try work out what’s going on with the can stream or if it’s specific for a certain model ?

Thanks

Which model year?
Vehicles before the facelift don’t have a full CAN bus, but VAN+CAN.
The CAN stream won’t work in those cars.

Another thing is that you want VW and Citroen streams on a single bus, which probably creates CAN ID conflicts.

It’s 2007, any idea of its possible to update the modules needed ? Really could do with the dash working properly

Understand the paddle shifters may be interfering will get a usb 2 can and try work it out

Any idea if there is anywhere I can see the can stream so I can do some poking around with usb 2 can?

5

I will check on Monday of there is a potential CAN bus conflict.

Thank you and can you tell me if the can stream will work

With a 2007 car?

7

use light client to log the can stream

The switch to full CAN was in 2006.
So you are good on that front.

But there is a CAN ID conflict.
The Citroen dash is using IDs 0x208 and 0x488. The same as VAG ABS and DSG. In that case, it’s impossible to have both systems working on a single CAN bus.

The only solution to make it work is by having two separate CAN buses.
For that, you either need EMU PRO, PMU, or ADU.

With EMU PRO, you would still need our CAN gateway that we are testing currently, because you need two buses that are 500/250 kbps, and one bus in PRO/PMU/ADU is locked to 1 Mbps.

You could add PMU and use CAN 2 from PMU to control the OEM dash.

Or you can get an ADU and ditch the OEM dash.

Unfortunately, there is no simple solution for the combo you got.

Thanks for all the info may look at a adu to solve it

Or may build something, is there somewhere I can get details if the can stream?

Thanks for taking the time to look into it

Thanks

I have now added a adu to the car but without the c2 canbus option selected in the emu the car goes into eco mode and turns off stereo windows etc and also power steering does not work.

Are you able to provide me with the canbus data to enter into the adu to resolve this?

Thanks

checkEngineStatus = 0x4 when there is check engine

sendDataFrame(0x488, 8 ,cltCan, 0x22 ,0x5d ,checkEngineStatus ,0x00, 086 ,0xff ,0x52);

rpm = RPM * 0,0318
sendDataFrame(0x208, 8, rpm ,0x33 ,0x2F ,0x3F ,0x18 ,0x03 ,0x01 ,0x40);

sendDataFrame(0x348, 8 ,0xe0 ,0x58 ,0x2c ,0x3b ,0x18 ,0x03 ,0x01 ,0x40);

And I just add this to export can in the adu?

Thanks for the info

Yes just create those 3 frames

14

Great thank you appreciate it

15

Could you explain how to enter the rpm and check engine light section? Have got all the rest in

Thanks

All working now do you have the abs stream also so we can get it to display speed?

Thanks

Adu with the emu and Dsg works so much better :ok_hand:
