our shop purchased a s40 that was hit in the right front corner, no frame damage. We fixed her all up and replaced the diriver air bag then we went to turn off the airbag light at the dealer and we could not cause there were some hard codes that didnt reset.
pass side seat belt tensioner
pass and driv seat belt buckles
pass and driv side air bags
left front side impact sensor
driver airbag stage 1 and stage 2
Now only the driver air bag went off in the collision(no pasenger) so why would all these codes come up that shouldnt. I would understand seeing driver seat belt tensioner and buckle and then replaceing the clock spring, but all this other stuff has us puzzled.
so we replaced the module with one supossidly not in an accident and then the clockspring and brought it back to the dealer.
the codes now read:
pass airbag stage 1 and stage 2
driv airbag stage 1 and stage 2
pass and driv seat belt tensioner
i am thinking that the modules are storing different codes and maybe we need one that wasnt in a collision
the volvo dealer tells me the module does not need to be changed untill 3 accidents. also they tell me i have to replace all of the items that come up as codes, but why do i knoe get different codes with diferent modules
