KOpel  MDI problem
Hi guys.

Can help to solve problem

I have a problem with the MDI. Communication with the K line works great, but when connect the MDI to Astra J or Insignia, blocked vehicle, ABS light up, AFL, Power steering light up also...And the vehicle will not start, there's something wrong with the CAN bus communication.


Thanks

RE: MDI problem
Regards to all,

I already asked once about the problem with MDI. Here I am again ... I have MDI and when I connect it to a vehicle with CAN bus communication, everything blocket. Then began to turn on lamps and warnings ...as I wrote in the first post.

Loki954 wrote to change the MCP2551. I was honestly lazy to do it, in fact I could not find MCP2551, so I left the problem to waiting.

Did anyone have a similar experience?
Can anyone help me solve the problem?

I'm sorry, but I did not understand that. Have you solved the problem or not?

RE: MDI problem
did you try to reset the MDI and do the recovery process with the MDI manager?
