M620 malfunctioning speedo and odometer..help!

AK ducati · March 01, 2018, 11:14:52 AM

Sorry to resurrect an old thread. This is what happens when I foolishly get two more toys instead that then take up too much of my time

I finally got around to contacting SOS diagnostics about my ECU, and he also suggested that I could instead reprogram my replacement cluster to run with the current ECU and not lose the immobilizer. I'm tending towards doing that rather than disabling the ECU immobilizer since there's been a rash of auto thefts over the past year in town. Just got off the phone with the nearest Ducati dealer in Anchorage, and a replacement instrument cluster is $910. Anyone have any suggestions as to where I can get a cluster for cheaper? I'm okay with a used cluster, as long as it works. Thanks! Edit: I did look at Ebay, and looks like I can potentially get an S2R 800 cluster, with key, ECU, tank cap etc for cheaper. Would that cluster be compatible with my 2006 M620? And since it comes with an ECU, I guess that would take care of any reflashing issues.

The cluster should work fine, the mapping on the 800 ecu, debateable.

Have you fully disassembled the current gauge cluster? (Popping off the needles and removing the circuit board) I have found condensation created corrosion that I was able to clean to get a previous cluster semi-functioning (left blinker was always on).

Hmm, thanks, the ECU is what I was wondering about (wasn't sure if there was different wiring that might cause problems). I guess it helps that the cluster itself from an 800 will work. I've found used 800 clusters, but not used 620 clusters so far. Also I have not disassembled my current gauge cluster. And I'm sure the problems are condensation related since the Monster is outside all summer, and we get a ton of rain. But now that you mention it, I should try taking it apart if that helps, since I haven't got anything to lose. Is it a fairly complex or straightforward process?

Also, where is the ECU located in the M620? This is sometimes why I prefer working on my old Wagoneer instead.....

The gauge removal is simple, but you just need to be gentle and test BEFORE reassembly, as you need to pop the needles off and they are another gauge weakpoint.

Unplug gauges, depending on year and dash unit you may need to unscrew the middle face plate or just pop it off. Then a small torx bit will remove the front face with the glass. CAREFULLY pop the needles off, remove the circuit board and look for any signs of green corrosion or dirt etc. Get a q-tip and some contact cleaner to anything you see. Then before reassembly, plug in and confirm everything works like normal (without the needles). Then reassemble up to placing the needles and again, test with dash to see the needles do a full sweep and return to zero. Adjust as necessary. Then you can finish buttoning it up. I'd also get some grease on the rubber gasket to help waterproof (because the stock rubber is next to useless otherwise).

I ran s4r gauges on my 620/800 with no real issues, along with 695 and 620.

As for the 800 mapping, it may work kind of close, or you'll have to spend a couple hundred on a reflash to a 620 map. I know my 2002 620 had the adjustable TPS, where the 800 map required the nonadjustable unit. You may have the same nonadjustable unit on your 2006, which means the only difference is fueling.

Thanks for the tips, I appreciate it! I'm hoping to be able to take it apart this weekend and clean it out. I'll try that route out first, and if the cluster still doesn't work, guess I'll have to get a replacement dash.

-wait!- I had a similar problem on an 06; I got some good advice on DMF to check the connection on the bottom wire clip to the button on the screw in sensor; bottom right side of the bike; and voila! fixed it fixer than fixed.

Hope that works for you too.

AK ducati · March 16, 2018, 09:54:20 PM

Well, I'd already taken it apart last weekend

Got to put in back on tomorrow and see if it works! And evidently I can't figure how to post photographs from Flickr on here.

Good luck.

There's a how to in FAQs and Policies. Takes some practice, but even an old Luddite like me can do it. Posting Flickr links is easy but trimming each end of the link reveals the pic.

AK ducati · March 17, 2018, 12:43:47 AM

Oh I went through the FAQ's and still couldn't get it to work. I know that it's operator error from yours truly

I tried to just post the link, but when I previewed the post, it didn't show the pic. I'm happy to hear someone else use the term "Luddite"

. I mentioned that I was one to a 25 year old, and she looked at me with this "I don't comprehend what you say" look...sigh.

Well, this Luddite is going to try posting this pic again:

Nope...

If you're posting from a phone, flickr is impossible. If you're on a computer it's relatively easy.

Okay, trying this again. I finally stumbled my way on finding the BB code from for the pic
