Has anyone ever done this and or had any success on a reset without a diag tool?
Contrary to popular belief, I've just found out that you CAN reset the
dashboard SRS light yourself - no Rover dealer required !
All you need is a paper-clip.
Directly under the steering wheel, just under the bottom of the dash board,
above the pedals, you can see a wide grey connector. A few inches towards
the drivers door from this, is a horizontal 2-pin yellow connector - with
nothing connected to it. Bend your paper-clip into a U shape, and stick the
ends into the 2-pin yellow connector, so shorting the pins.
Turn on the ignition, and the SRS light will illuminate for a few seconds,
and then go out.
Now pull out your paperclip (but not right out), so breaking the link.
After a couple more seconds, the SRS light will illuminate again.
Now stick the paper clip back in, making the link again, and after a couple
of seconds, the SRS light will blink twice.
Remove the paper-clip, and then switch off the ignition.
You have to do this all fairly quickly - you only get a few seconds between
each step. Because you can't see the yellow connector and the SRS light at
the same time, it's really a two-person job.
That resets the SRS system - next time you start the car, the lamp will be
off - obviously this only applies if you have no fault ! If there is a
fault, the light will illuminate again. I know I had no fault, because the
light illuminated (and then stayed illuminated) when my alternator died.
It is tricky but it is 100% correct (stolen from Rover by an enthusiast)
Let us know how you get on.
