Another Brake Pad Sensor problem/question

2006 GT, 20k miles
Change rear tire
Pads worn...sensor (wire)still intact but worn.
Replace with new pads and insert sensor...crack off small side piece of plastic holder, but it still slide into the brake pad slot.
Zipp tie wire back in place.
Change rear gear oil.
Ride for three miles...no problem.

Next mount up the "Brake sensor idiot light appears" after a couple miles.
Check wire..seems intact...pull on it thinking wire is now broke (sensor light is on)...it pops out the plastic holder and wire.
Wire still complete (not broken) but plastic holer is....not usuable again.

Ride 200 iles with idiot light on...no brake problems.

I have read about tight zip ties...maybe that's it.
I have read about GS-911 to reset the idiot lights.(no one near me has one)

So how do I get this light to turn off?
BMW only?

Thanks,

Mike

Again, the "sensor" is just a wire loop. Once it wears through it breaks the circuit and the light comes on. That can also happen if the wire breaks due to over-tightened factory zip ties, or during subsequent maintenance, etc.

Some '08 bikes with newer software will reset the light by itself once the connection is solid again (new pads/wire, repairing the broken wire, jumping out the factory plug, etc.).

If you don't have that newer software, then your only choices are a GS-911, a trip to the dealer, or a piece of electrical tape over the annoying light.

Sooner, or later we are all buying a GS-911. It's not even the money that is at issue, its the inconvenience of going to the dealer. As described here in other threads you can maintain the bike with the dealer, get it home and a week later the light can come on for valves, or who knows what else. Got to get the GS-911, I'm waiting for the latest beta version, I here its powered with dilithium crystals.

I was afraid you guys were going to say that.
I know the wire is still intact at the sensor area...although a tight tie wrap may be the culprit.

But from you reply I'm guessing that the light will stay on???

Unless you have the latest '08 software, then yes.

On my 07 the light is staying on. The dealer is nice enough to send me a pad set (for one caliper, the side with the sensor). I re-wire-tied the wiring, no idea if I fixed it or not.
I'm pretty seriously considering finding out for sure if I can remove that pad sensor warning light bulb. Tape seems so crude.......
Could the cluster version be updated so it will reset if it sees a complete circuit?

If you get the latest software uploaded by the dealer, then the light will reset itself once the circuit is fixed.

As for "pulling the bulb" I don't think there is a separate bulb there in the traditional sense. All of the parts diagrams show it as a unit, without any break-down parts. I think it's probably LEDs or something similar soldered to the main instrument control board.

If you do feel like pulling the instrument cluster out and checking to be sure, let us know.

And the tape was a joke, although for some guys, that's as far as their mechanical skill goes . . .

What else would be affected by the new software? Anything potentially negative?

I believe that feature was introduced with software update CIP 10.0. You can find details of that update in this thread.

Thanks, I don't see any negatives there, although there is a lot to read and comprehend, but I think I got it. Yeah that "mls/h" instead of MPH is kinda screwy lookin', I saw that and remembered it.
