W204 - Airbags deploy while car parked!!!

1
A W204 C200CGI has had its driver and passenger airbags deploy while car was parked!


What could cause such a problem?

Anyone with wiring diagram for the restraint system? I want to reinstall the airbags but need to understand what could trigger this so that if an ECU or sensor get that replaced too.

You should use WIS to find the wiring diagram so that you get known the involved ECUs and sensors.

WIS will not help with that.

Most likely defective airbag ECU.

Yes, quite unbelievable. Imagine that happening while on the highway! Can be cause of fatality. I thought these systems should have failsafe. Just where ECU got energized from to trigger the bags I would never know. Car was parked and locked!!

Hey Willis, Thats a first to hear. Though I have seen quite a number of ECUs generating Internal faults. Hit me up and we can go over It. I can send you Workshop info on how to replace the unit and the airbags.
If my post help you then please thanks and Rep will make me feel motivated.
