SRS warning light 300tdi on. Is there a reset procedure?

(1/2) > >>

muddyjames:
The light was always off but then the disco went to  a  garage for repairs and since then the light has been on and the right hand S flashes very slightly.

The battery was disconected when in the garage. Do I have to reset something to turn the light off?

Tyke:
Had the steering wheel and airbag off mine a while a back.

If this has been done to your vehicle you have to leave the battery disconnected for some time . . . . say ½hr or so . . . . for the capacitors in the SRS circuit to fully discharge before you break the SRS wiring to remove the bag and streering wheel. If the caps are fully discharged all will be well when re-connected. If not, the circuit will think there is a fault and the warning light will not go out.

Take it back to whoever did the original repairs and complain about it.

muddyjames:
so if I disconnect the battery for a few hours it may sort it out?

The job the guy did was replace the alternator pulley and rebuild the crank shaft a little bit as it had worn down when the puley became loose so the battery would have been disconectedfor a long time having that done.

I will try the disconect battery idea and see what happens.

spy:
Not sure about these but the "airbag" light is not just for airbags on most cars.  It doesnt sound likely to be connected to the alternator or crankshaft..

Very common on "normal" (aka boring) ;) cars for srs warning lights to be caused by iffy wiring to seatbelt pretentioners.  

Might be worth a look!

muddyjames:
I know the air bags arent linked to the alternator pulley. What I was trying to say is that the battery got disconected when the mechanic was repairing the pulley.

Do 1994 discos have seat belt pre tensioners? I know modern day cars dobut is 1994 classed as modern day (boring as you say) cars?
