I replaced my GPS a couple of years ago. It took to the bike without any issues. From what I've read, it appears as though many have shared the same experience. But I'm sure it must have gone the other way for some. For those that had to initiate and perform the relearn procedure, were you able to initiate the procedure as outlined in the Tips and Tricks bulletin without any issues? It seems to me that I ran across a thread (at some point in time) in which an individual had difficulty initiating the procedure. Just curious.
 
Well, JP has solved this one. The current version of MelcoDiag (version 1.0.6.5) includes a "Gear Reset" button under the "Resets" tab. Also included is a "Rolling Reset" button for Ducati models which require the same.

Tips & Tricks Bulletin SRV-TTB-16-003 is the relearn procedure proper. MelcoDiag is used to initiate the procedure and enter "learn" mode. The procedure contains 16 steps, but only the first 8 are required to teach the 1199 (in this case, a 2012 1199 - base model). The indications which are observed as the procedure is performed will differ slightly from those described in the Tips & Tricks bulletin. The procedure may (or may not) operate in the same manner for the other Ducati models (899 Panigale, Diavel, Multistrada 1200, Hypermotard 939, Hypermotard 939 SP, Hyperstrada 939, Monster 1200 R-all versions/model year) listed in the bulletin.

Connect your laptop to the bike, open MelcoDiag, click on "Gear Reset" under the "Resets" tab, close MelcoDiag, and disconnect the cables from the bike. When you click on the "Gear Reset" button, a flashing "C" will appear in the gear window on the dash pad and will flash in sync with the dash pad's green neutral indication. You can key the bike "ON" or "OFF" as you please, as each time the bike is keyed back "ON," the flashing "C" and neutral indication will reappear on the dash. You won't be able to clear it until the procedure has been successfully completed. This initiation process can be performed prior to warming the bike, or immediately thereafter... it makes no difference. Worth noting... once the process has been initiated (a flashing "C" and green neutral indication present on dash), the starter button will be inhibited. The side stand must be raised and the clutch lever depressed in order to start the bike. Throttle response will be erratic as well... simply let the bike run at idle speed until reaching the temperature required to perform the procedure.

1. Place the rear of the bike on a stand and put the bike in neutral.
2. Beginning with a cold engine, start the engine and allow it to warm. Coolant temperature, as shown on the dash, must remain above 176 degrees throughout the procedure. It doesn't take very long to perform the procedure, but to ensure that I had ample time, I allowed the vehicle to heat to more than 200 degrees. Once the bike has warmed sufficiently, stop the engine. Return the key to the "ON" position thereafter (you can key the bike "OFF" and then return it to the "ON" position, or you can leave the bike keyed in the "ON" position and toggle the handlebar kill switch to stop the engine... again, it makes no difference).
3. Although the letter "C" and the green neutral indication are already flashing on the dash, depress the clutch lever fully and release.
4. Push the rear wheel forward and simultaneously push the shift pedal downward, selecting 1st gear.
5. Depress the clutch lever fully and release.

Note: As the clutch lever is released, a "-" will appear momentarily in the dash pad's gear window as the clutch switch toggles states.

6. Wind the rear wheel slightly rearward and then turn the wheel forward while simultaneously pulling the shift pedal upward, selecting 2nd gear.
7. Depress the clutch lever fully and release.
8. Continue working in the same manner (repeating steps 6 & 7) for 3rd, 4th, 5th, and 6th gears.

The learning part of the procedure is complete. Yes, the letter "C" and the green neutral indication will still be seen flashing on the dash. Key the bike "OFF" and allow it to power down completely (~30 Seconds). Thereafter, key the bike "ON" ...the information has been acquired and the gear window on the dash should correctly reflect the actual gear that's been selected. Verify all gears. If a mistake was made and the dash doesn't correctly reflect the actual gear that's been selected, the procedure will have to be repeated. Should that be the case, key the bike "OFF" and allow the system to power down completely (~30 seconds). Thereafter, key the bike to the "ON" position and repeat steps 3 through 8, keeping in mind that the coolant temperature should not fall below 176 degrees during the procedure.

Note: During the procedure, as the rear wheel is turned forward and a gear is selected, a sound may be (or may not be) heard emanating from the airbox. It sounds like the ETV motors cycling... no cause for alarm.

This procedure has been repeated during four separate sessions over the past two days and it works consistently. I won't be able to ride until the weekend, but if any anomalies are experienced during the road test, an update will be posted.
 
Note: if the bike didn't acquire the gears correctly, before repeating steps 3 through 8 as mentioned above, it'll be necessary to use MelcoDiag to re-initiate the procedure so that the flashing "C" and green neutral indications are once again present on the dash.
 
Update... I performed a road test, returned home, and all gears were registering correctly. I allowed the bike to cool and later keyed it back "ON"... 2nd gear registered in the gear window; I lost the neutral indication. I repeated the procedure, did another road test, and observed the same results.

I did some experimenting with the procedure shown in the Tips & Tricks Bulletin SRV-TTB-16-003. I was able to observe the results mentioned in the second half of the procedure (essentially the verification phase). The only notable difference is that each gear appears in the gear window after releasing the clutch lever as opposed to appearing while the lever is depressed. Believing that I was on to something, I performed another road test, but the results were the same as mentioned above. I ran through this a second time as well. Again, the results were the same.

Next, I conducted the procedure without heating the bike. I performed a road test and lost neutral halfway through the test. After arriving back home and allowing the bike to cool, the dash correctly indicated neutral once again.

With the exception of neutral, the bike ran flawlessly and registered all gears correctly, regardless of the manner in which the procedure was conducted. While temperature is certainly seen to influence the results, it appears as though neutral is the most susceptible. It's as if the procedure must be conducted at a very specific temperature to ensure high and low temperature functionality. The bulletin provides little guidance, only stating that the engine temperature should remain above 176 degrees throughout the entire procedure.

So, more experimenting is called for. If anyone else runs through the procedure, share your results. You may not experience the same problem. It may be related to my bike, my sensor.

I´m sorry to say that your description of the "Gear learing procedure" is wrong.
I will in short time make a description of what I did
 
1. Place the rear of the bike on a stand
2. Select Neutral.

4. Start engine and Warm up until Dash Coolant temperature is more than 80C (176F) and stop the engine with kill switch.

Have tryed this 3-4 times and it works every time.
 
ok all this...but my problem is i connect the Melco i select the Gear reset but is not do it nothing...or show me ''-'' or the 1st gear...not reset and i don't no why...the degrees is 87c and the connect is ok with my bike...

Try between 4 and 5 to do a KEY OFF wait 1 min and then KEY ON

On Melcodiag frontpage (5)
- Is VIN number. Showed ?
- Are ECU + BBS + Dash green ? (connection to all ok)
