Model K26/R 1200 RT/0368/2007/08 is K-Line 1 & 2 only no CAN on 10 pin diags socket
There is an odd connection on pin 7 for alternator test which may upset a D-CAN adaptor

Ok, so you suggest to rewire the connection in some way?

The K26 does not use CAN Diag, it only uses K-Line on the 2 K-Line pins so a KK USB adaptor can be used
I have used the dual K-Line adaptors to look at BMS-K/KP models without issues, works well, the BMS-K/KP acts as a gateway to the CAN BUS

No rewiring of the 10 pin socket is needed, the presence of the odd signal on pin 7 may be confusing the D-CAN adaptor when it looks for active protocols

I disconnected pin 7, but it didn't help. Is there anything else I can try?
