SRS Error B0117 - impact sens. or sidebag?

[tzok]

Car is a Grande Punto 1.3 2006. The SRS warning light is lit and I've got an B0117 error which, according to FES, is "Front impact sensor" while other sources indicate that it is a "Passenger sidebag - low input". This is an B0 error, so I guess it should be a generic OBD-II code, or there are no generic "B" codes and each car manufacturer have own code definitions?

SRS error came out while driving on flat, straight road, car never have had a collision.

Sorry, but the info about B0117 in this airbag's documentation is:
Faulty component: Front impact sensor
Possible reasons: Component faulty or Programming faulty

I don't have any other details.
It is possible that there is a problem in the wiring of this sensor.

Ok, your definition was ok, it's wiring harness was damaged. My GP has only two airbags so I didn't expect it to have any external impact sensors - normally the crash sensor would be integrated with the main SRS unit. But I'v got two-stage airbags and so called "early impact sensor" is present (it is located behind the front bumper, and has a wiring harness common with the front anti-fog lights).

First check connectors... Fuse... If all OK is, than do next:
- Find a used sensor from a donor car and replace it... That is the easiest solution... Does not cost too much...

Thanks for your response. Unfortunately I can't find any similar sensor anywhere (its called TRW BR Sensor Crash Airbag 5177524010060243)







I also took it to the local Fiat registered Dealer and they replaced the sensor (costing around £226) but that didn't resolve the problem. Then they further investigated and said some more work needs to be done underneath the body as it looks like it has been involved in a crash and some parts need replacement costing another £300 which I refused as I can't afford it. Also the car has never been involved in any crash since I bought it two years ago and If it was involved in a crash before that why didn't the Airbag light went off in the last two years. By the way they did not tell me what parts and I also returned their sensor as it did not solve the problem, only paid them £90 for checkup.

Please help I am losing the hope of fixing it ever....
