RDC
« on: August 08, 2013, 09:04:32 PM »
Hi,
I had  my ADV stopped for 2 weeks and when returned from my leave and riding the bike, the front tyre pressure monitor just didnt show any measure; just __:__. When testing with the GS 911 everything looks normal, no error code. Is it possible that even with no error code showed the TPMS doenst work? If so is it a problem of the batteries inside the sensors? If for any reason the sensor codes writen in the ECU desapear is there any other way to re-write them as on my 2 sensores there's no 6 digit code label where we can copy it and write it through the advance settings..

I assume you have looked at the following link;
http://www.hexcode.co.za/products/gs-911/procedures/rdc

Does your GS-911 show the "Current ID: {7 digit-number}" for wheel set A, front & back?

Normally, when the battery of the sensor goes down a certain level, your dashboard should have shown the infamous yellow exclamation mark plus "RDC !".

According to the user-manual, only when "--" or "-- --" are shown plus the general alarm (red exclamation mark) there is a malfunction of RDC system.

Please be aware the sensors only go awake above 30 km/hour.

I would try option 2 in the aforementioned link;
- First take a ride for 5 minutes, ensuring that you have reached the speed above 30 km/hour for sure, for at least a couple of minutes.
- Upon return, the sensors should be "life" for at least 15 minutes when the speed is 0 km/hour, so hook up the trusted GS-911 and see if any error-messages are recorded.
However, as stated on the aforementioned link, this is *not* the right way to relearn the sensor. (!)

If you want to relearn the sensor-ID, I guess you must wait at least 20 minutes or so (after riding), and use the Emergency method (Option 2: waking a sensor manually), by leaving a substantial amount of air out as described in the aforementioned link.
(make sure you have the means to bring the tire back to its correct pressure).

PS: You can replace the batteries of the sensor;

Dear,
Thankks for the support.
GS 911 doesnt show any sensor ID for wheel set A front and rear, and the yellow triangle is ON.

Just to be sure;
I guess there also no sensor ID's shown for wheel set B either, right?

Are you using the GS-911 beta software or the "regular" v1303.3 version?
You may want to try both software-versions, just in case, to double-check.

If the above doesn't help and the described emergency-method (letting air out for at least 10 seconds on the front tire) does not wake the sensor either, and the GS-911 software does not report any faults, I guess you need to consider visiting your BMW dealer then.

Ask them to record the sensor-ID's for both sensors for you on a piece of paper, using their RDC tool.
You then go back into the GS-911 software and enter these codes yourself and have them available in case of future issues.

If the BMW dealer can't seem to wake and record the sensor-ID's for you, it might indeed be that the battery is flat of that sensor(s).
And, whilst you are at it and depending on your standing relationship with that BMW dealer, you may want to consider requesting them to hook-up your bike to the BMW diagnostics, record any faults (and perhaps erasing them) and see if (via the secured internet-connection) any software-updates are available for your BMW.
Sometimes the BMW dealer do charge a "nominal" fee for it, so you may want to check that prior to that endeavour.

Also, as you are there already, again depending on the standing relationship with that BMW dealer, you also may want to request a printout of the repair-history & also check any outstanding recall-actions.

I have taken to printing out the TPM Sensor IDs and pasting them inside the client's service book.  That way, if there is ever a failure, I can just refer to the book and enter them manually.

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.

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.

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%.

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.

Thank you for sharing that information;
One would almost conclude that the described emergency-deflation method does not work (anymore).
Perhaps due to different versions of the RDC valves?

Knowing BMW, and my experience with them, I would not be surprised if that emergency-method only works with certain versions of RDC and/or bikes.

As the explanation provided by the BMW mechanic does make sense to me.

It makes sense that the sensor first has to be in the wake mode befor it can dedect a rapid loss of air on deflation.

Just chiming in with my 2 euro cents.
Diapers and politicians should be changed often.

Anyone know whether this Wake Up Tool will work on the TPMS?

Claims to wake all existing 125KHz sensors.

Although you might not be able to read Dutch, on the list of supported brands, BMW is missing;
http://www.auteltech.nl/resetters/570/MaxiTPMS-TS101
(you can see all the car-brand logo's on the bottom of the page)

So, I tend to say no, BMW motorcycle RDC are not supported (either)

But perhaps best to contact the manufacturer themselves;

Thanks for the info but....BMW might be missing in the list because the sensors of BMW cars don't need a wake up tool as they are installed more or less automatically. One of us should contact the manufacterer. As DutchMidiMan and I both speak Dutch, one of us could do that.
@DutchMidiMan: you or me??
