Pre-heat! :-)

Great 🙂

I’ve already ordered a pigtail cable, so we’ll see what we can find out. 
The navigation and climate control is on the M-bus, so I hope we will find something useful on that bus.

The Fiat 500e uses the same pins for 2 of its CANs, so the same cable would be useful for more than just the Kia. (Assuming there’s useful info on both buses)

Relatively easy. I just give them pinouts, some money, and a week later a bunch of cables arrive.

There is a minimum order quantity of 50 cables from the supplier, so it has to be justifiable.

Perhaps best to have a look at that M-can bus (with a hand-built cable), and see if there is anything on it that makes this worthwhile. You can find OBDII pigtails on AliExpress/eBay/Amazon that make this relatively simple (only need to solder the DB9 end).

Hi,

We might need a special cable for the Kia Soul EV, as it has two CAN-buses on the diagnostic port and it doesn’t match the ODB2-cable nor the Nissan Leaf-cable.
Then C-can uses the standard pins 6 and 14, but the M-can uses pins 1 (high) and 9 (low). 

The M-can should be mapped to CAN1_H (Pin 5 on DB9) and CAN1_L(Pin 4 on DB9):

J1962-M   DB9-F   Signal

1         5       CAN-1H (M-can High)
4         3       Chassis/Power GND
6         7       CAN-0H (C-can high)
9         4       CAN-1L (M-can Low)
14        2       CAN-0L (C-can low)
16        9       +12V Vehicle Power

I don’t use the M-can at the moment, and I’m not sure I will, but if I do we might need to have a special cable made for the Soul EV. 
Is that something that is easy to fix?

Regards,
Geir
