Hex-V2 K1/K2 test

[trv2]

I encountered a problem for the first time and couldn't find an answer in the user manual. When K1 or K2 is faulty (short to +12V or ground), I get the message when pressing the test button
CAN: Testing, K1: OK, K2: OK
VBat: 12.08V, VIgn: 12.15V.

However, if the interface is not connected to the car, the test message shows:
CAN: Testing, K1: NO POWER, K2: NO POWER.
VBat: 0.01V, VIgn: 0.01V.

I connected 16 and 15 pins of the interface and don't get a message about K2 shorted to +12.
How then to determine the problem with the wiring using hex-v2?
Am I correct in understanding that the hex-v2 cannot determine the state of K1/K2?

Upd. It works.
the interface checks the K-line only the first time it is connected; if a fault is caused after connecting +12V, it will not be detected.
In addition, the buzzer is activated at this moment.

I have no idea what you're doing.... K2 should only be a thing on some older platforms... what vehicle are you connecting to?

Thank you for the update
