RDC

<< < (2/5) > >>

Inspector Gadget:
Indeed, good suggestion.

It would be even better if GS-911 would be able to export such settings.

Or even better/simpler:
Include it in the AutoScan report, next to the service-interval setting. (for example)
Run the AutoScan or Report and save it for future reference.

Same RDC problem here in Belgium: after a puncture of the front tyre on my 2009 GSA, I put in a spare wheel that I had in my shed. As the wheel came complete with a tyre on it, I didn't know the sensor's ID. I tried the valve deflating method as described in
http://www.hexcode.co.za/products/gs-911/procedures/rdc
I even took out the internal valvestem to have the quickest deflation possible. Neither of these methods worked out, not from cold neither after a ride to "wake up" the sensors. It might be that the battery in the sensor is flat. I tried the same method on a 2010 GS with front and rear unknown sensors but it didn't work out either. The only strange thing to mention is that the puncture sign came on so the sensor is talking in some way but not telling his identity. I tried the standard version and the beta version.

Belgians are known to be stubborn so...as I knew the rear sensor on my GSA was in perfect order and I could read the sensor's ID with the GS 911, I erased this ID (after writing it down---we are stubborn, not stupid) and tried the alternative deflating method. It didn't work.  Only when I put in the ID numbers of the sensor again, it worked again. Next weekend I will drive to the dealer to find out whether the sensors can be woken up by their specific tool or whether all these batteries are flat.
Did any of you actually had succes with the deflation method or is this an assumption on how an alternative way of matching a sensor tot the ECU could be? I'll keep you informed after my visit to the dealer.

Inspector Gadget:
I tried the emergency-deflation method on one occasion, it did not work.
But were stretched for time so only tried it 2 or 3 times.

In my case it was the situation that supposedly the battery went flat on the front RDC of a 1200GS. So, the RDC was replace by a new one, had the code-sticker(s) noted on the new RDC.
Enter the new code via GS-911, and that worked fine.

Jughead:
I had the same today.  http://forum.hexcode.co.za/forum/index.php/topic,131.0.html

Once I had fitted the new sensor I went to the Sensor Learning function.  Was prompted to wake the sensor up, so with the bike on the centre stand, I spun up the rear wheel to around 50km/h for about 2 minutes.  No wake up.

Then tried the quick deflation, about 3 times.  No luck.

I had fortunately written down the code of the new unit before replacing the tyre, so entered it manually.  After that, everything worked 100%.

PDM:
As mentioned last week, we had 3 sleeping RDC sensors in 2 motorcycles. As the deflation method didn't work, the question arose as to whether the batteries could be flat in all sensors (unlikely but not impossible). In the meantime, I also spoke to a BMW car mechanic as some BMW cars also do have RDC sensors but unfortunately for us motorcycle enthusiasts these sensors are learnt automatically by the vehicle without any tool.
So we went to the BMW dealer yesterday afternoon, my wife on her 2010 GS and me on my 2009 GSA. The mechanic was very interested in my sensor/deflation method/GS 911 story but thought the method is unlikely to work since the wake up tool does 2 things in his opinion: first of all, it sends a radiofrequency signal to start up communication with the sensor and secondly it also creates some magnetic field as there is some kind of magnet in the sensor that makes contact when the wheel is spinning and only then the communication with the ECU starts. This, he said, is why you only get readings after driving a few meters. Si non e vero e ben trovato.
Anyway, he was very helpfull and managed to wake up all three sensors with the first version of the wake-up tool.
