The airbag light on my 2006 DC never comes on and the passenger side always reads "Airbag off". I took it to my local dealership and they diagnosed a shorted out driver's side buckle wiring, and a faulty occupant sensor ECU (the one under the passenger seat). They offered to fix it for the low, low price of $1,060. I told them I'd get back to them ...
My fear is that they'll fix those two items and discover that there's more to it than that. I've read through the variety of threads on here about airbag problems and from what I can tell, there are two ECUs at work in the system - the occupant sensor, and the center airbag ECU. It seems to me that if the occupant sensor was shorted out, the other ECU would cause the light on the dash to illuminate. Wouldn't it? Since I'm not getting a light at all (and they did check the bulb on the instrument cluster), it seems to me that there's more to it than just those two items they want to replace.
I'm tempted to just purchase and replace those two items myself (yes, I understand the inherent danger in fiddling with the SRS system), and then see what happens. If I were to do that, is there any recalibration that needs to be done, or is it just plug and play for that sensor/ECU?
I'm still on the fence about how to proceed, so I'd appreciate any information/advice from the airbag experts in the forum.
Thanks in advance.
