I have a 2003 E39 so there is no OBD1 anymore. Worst cast scenario you just need to modify the cable & stuck a switch on it to toggle pin 8 on/off as needed.įinally there are a lot of rubbish adapter cables out there. The ones with pin 8 active are just older versions of the cable. The one with it disabled is ideal for e90 newer than 03/07 & that era, these leads often come with a black adapter to re-enable the pin 8 (by just tying it to pin 9) so it will also be suitable for e46/e39/e63 etc. With these K DCAN cables there are two subtle different versions, one with pin 8 enabled, one with it disabled. In fact thinking about it I use the same adapter for INPA, DIS and ISID. As mentioned if you only use the adapter on the e39, run the utility once and set the adapter to K CAN and leave it at that. I use the DOS version of the DCAN utility. I always switch my K+D CAN adapter between K and D CAN protocols as I need to, depending on the car that I'm connecting to.
The OBD port only allowed access to limited modules, I think only the DME in fact. Earlier e39 had both the OBD port in the cabin and the round 20 pin connector under the hood. How do I switch back to K-Line? Just by connecting the two pins or is further action on the computer required? If you run it the first time you connect to a DCAN car, your computer will retain the settings. You only need to run it when you are switching between modes. Is it necessary to do so every time I want to use DCAN or is the interface staying in DCAN mode once I ran DCAN.exe? I have only used my K+DCAN interface with DCAN cars. As soon as you connect the interface to the car and your computer, run DCAN.exe to configure the comms rate. Is there anything else to do for switching from K-Line to DCAN then disconnecting pin 7&8? Unfortunately I don’t have a DCAN model available. Yes, I think connection by soldering is a bad option as it limits the usefulness of the interface, I have an adapter but consider a switch to be a better option. So you have to physically connect (K-Line) or disconnect (DCAN) pin 7&8?
K DCAN WIRING HOW TO
How to use/switch/connect to K-Line or Dcan pin 7&8? I have one of those K+DCAN USB cables and I am confused about how to switch the modes of it.
