Got to be honest, he really didn't hit the object very hard. It was one of those small red/white plastic barriers things. Onlt left a red scuff on the bumper but was enough to set if off
Hope that never fires off on my 370z
I remember reading it triggered on a gtr when he bumped tow bar on the car infront. Bonnet springs fired and the ecu went into safety mode.
Cost to reset and replace springs.........
Wait for it......
