Did you disconnect the battery out of interest? Guess with ignition off it might not have power anyway?Hey all,
First off thanks for this great thread.
Before you go out and buy the sensor just try and check the condition of the lead 3 wire from the sensor. I removed the front part of the seat cover but left the back still on - while I tested. My brown wire had a fault and it was in a tricky spot. Past where the zip tie that lashes the wire to the seat frame - but just before the hole in the seat mesh / seat bottom. From the naked eye it looked fine - but it had broken - so test. I know I almost gave up but thought as long as I am in here.
I used a razor blade to carefully cut away the protective sheathing that covers all three wires and then used the blade again to carefully expose a small amount of wire to check for any loss in continuity. First I checked the white and it was fine then brown and it was the culprit.
Some tight spot soldering but in the end that did the trick and the light is off. There is no resetting or doing anything else - all good now. Ohh I did put protective tape on the metal hole where the line was cut and also put some sheathing on the brown and then the 3 wire.
It took me an hour and a half and I would not consider myself a mechanic - fairly handy with some tools but that's it.
Also .... Have you seen the seat sensor bypass boxes you can buy? It keeps the airbag system activated and is plug and play.
Why would i not fit one of these?
