I've installed a FMB120 in my car, it seems to be working and I receive some data from the car, but I can't receive any alarm.
I receive other status codes (240/246), but I never receive the 236 status. I'm using the digital input 3 as stated in the manual, but nothing.
What may I be doing wrong?


Actually, I just receive the status codes

  • 239
  • 240
  • 246
Nothing else. I even have a CAN-CONTROL connected, so I should receive a lot more data
I'm also having the same problem, I'm sure I didn't leave a parameter wrong but it doesn't work, it seems to be a technical error, hope to get some help soon!

How to connect alarm??

How can I check the data of the states?
