SRS warning light won't go out, after cruise switch install!

Hi all: I replaced a broken cruise control switch on my steering wheel
today (1999 Disco 2) and after putting all back together I have the
SRS light staying on in instrument panel.
I was wondering if there is a reset button or something one must do
after re and re-ing the airbag.
I followed the removel procedure to the letter, disconnecting battery
neg first, then pos

I cinched up the torx screws very tightly though the bag doesn't seem
as set in place as it was. Not sure if this is the cause or not.
Any ideas?

It shouldn't need a reset, mine didn't. Sounds like something was
dislodged or something. Next time it's serviced, let them reset the
light and see if it stays off.

I just took it apart again and found I had pinched the shielding from
the ignitor wires between the bags flange and the steering flange
right where the torx screw tightens both halves. The bag seats much
better and the srs warning light is out.
All is good!

Not that I'm aware of. Didn't need to do anything like that when I
fitted cruise to my TD5.

Well IIRC there isn't a great deal of clearance but the air bag unit
should fit reasonably well back where it was. I suggest you power down
(battery neg terminal off) wait the 10 mins the take it off again to
check for trapped wires or such like. The cruise wiring has little
clips and things to hold it in a specific place and is only just long
enough. Make sure the loop of wire to the air bag unit doesn't foul
anything or get trapped when you put it back on.

Thanks David, that's exactly what happened as I explained in previous
post. The shielded wire wasn't in the clip but loose, and I accidently
cinched it between either flange. I placed it in the clip and cinched
back up and Voila....no more light.


Thanks

I hope you checked for and repaired the damage. There must have been a
short somewhere for the SRS ECU to be upset... From what I remember,
you may have trouble getting the sleeving back far enough (or off) to
see the actual wires.

Not sure I'd like to rely on the SRS ECU spotting if/when the wiring
fails, I would like to think that the self tests are pretty fool proof
though. Possibly worse is the damage allowing another short providing
enough power to fire the airbag whilst driving...

All valid points Dave. You're right in that it would be hard to peel
the shielding back far enough which I didn't attempt. I thought the
light may have stayed on due to poor seating of the 2 components, but
your description has me feeling a bit nervous now, and maybe I should
remove again and see if there is damage to the wires. A scary thought
indeed!

From what I remember it's just a fairly tough sleeving. All the firing
circuits for the airbag(s) are protected like this from the SR ECU to
the bag and in a bright colour.

Worth a look to make sure that it has no holes even small ones. The
firing circuit itself is tested by the SRS ECU so I should imagine it
would detect an open or short and signal the fault via the SRS light
(as it did...).

In fact, ECU signals when everything is ok. I have Disco wit no airbag and
installed newer instrument cluster. SRS warning is constantly on. So i have
to rewire cluster, pull out bulbs or install SRS.

Makes sense, you don't want the light to not come on because the wire
between it and the ECU fails... I also keep forgetting that most of
the indicators in the instrument panel are all similary controled from
the various ECU's.

Most are also LEDs rather than bulbs, so probably soldered in so
"removing the bulb" for your permenantly lit SRS light might not be as
straight fordward as you think.
