Hi all,

I had the airbag tell tale coming on now constantly. Before it used to come and go but the last week it was on everytime.

The DTC read the rear passenger Pretensioner showed an open circuit.

I folded the rear seats and took the trim of, made sure the all connectors are seated properly. It seems that the wiring harnes going from the front passenger seat to the back might have caused this.

Light is gone now for the last 4 days. Hope it stays like that.

However, I also found this connector loose and nowhere to plug it. On the driver side rear seat the wire endings seem to be taped.

Any idea what the passenger side connector could be for or is that just half-done work in the factory of not removing the connector?
