I got error codes 805 and 211 (wiring resistance and no signal from LH side impact sensor).

SO I purchased and fitted the correct LH side impact sensor and much better underseat connectors (SupaSeal). No joy. Changed the polarity of all the under seat cables, testing one by one, until...no joy. I am now getting another error, as follows:-

805 - front tensionor circuit - resistance too big
211 - Left side impact sensor - no signal
809 - left front airbag ignition circuit - resistance too big

I am totally baffled, and a bit fed up. I just don't get how the new (correct) LH SIS is not working. Is there anywhere else the wiring could be dodgy? In other news BOTH mechanical seat belt tensioners have lost their nuts and dangle under the seat but I couldn't see a pot or similar measuring the tension on them...or am I wrong?

Any thoughts, would be greatly appreciated. BIG thanks to the forum btw for all the info in Technical Help that has gotten me this far rather than crying into the IPK...

Best washes,

Paul.

Changed the polarity of all the under seat cables, testing one by one. Why would you want to change the polarity ?


In other news BOTH mechanical seat belt tensioners have lost their nuts and dangle under the seat but I couldn't see a pot or similar measuring the tension on them. They shouldn't be disconnected, in the event of a shunt, without them being connected they won't do their job of keeping you secure in your seat. There is no tension to be measured, why they are called that is that in the event of an rta the restraint system causes the ' tensioner ' to operate and tension, tighten, the belt sufficient to keep you safe in your seat.


As SPC says, condensation damage of plugs and pins is a favourite in this area and may be your problem, whilst you have been checking the wiring etc. you could have introduced the third fault simply by disturbing a loom which has another plug/socket with corroded terminals.
