I am screwed :D I don't know where that cable leads...
It shouldn't be too bad all those codes are related to one another, the Air bag sensor won't power on during ignition (B142A) based on my reading in the SM if the crash sensor is having issues. As Skyline said start looking at the electrical portions, start with the Air Bag Fuse then move on to the Wiring Harness and see if anything isn't plugged in or damaged.

The cable will lead from the front bumper through the Firewall to Air Bag Diagnostic Sensor which is underneath the front arm-rest.


Connection malfunction or short circuit to ground of harness and connector
• Internal malfunction of crash zone sensor
• Internal malfunction of air bag diagnosis sensor unit

You're a hero. Thanks a lot! I'll start looking this weekend. One more question: Some people say that Airbag module needs re-programming to reset and delete "crash". I think it is not the case here from what I see in Carista... What do you think?
According to the SM no need to re-program, just clear the fault codes and you are good the only exception is if you are replacing the passenger seat as their is some calibrations required for the sensors to operate and detect a passenger.
