Thank you sir!
Hi,
I think you are right ! I wonder the CAN filter only protects dashboard!!! My bike installed the Can Filter, after 2 days error "CAN line" again, I checked everything, finally I found the ECU was dead ! So I think M.A.E makes the CAN filter to protect only their dashboard !
So now I don't care about CAN filter anymore, the best way I can do that is find the exactly issue which detroy can bus system!
Could we find the problem together? Any information will be appreciated!
Ps: when I say the Can filter only protect dashboard, I mean the transient voltage could go anywhere, but now the dashboard built the block gate (CAN filter), so the transient voltage will go to the ECU where end of the can bus ! ( ECU & dashboard are ends of can bus with 120ohms )
Yes. I don't know about this specific case, but a real recall is serious NTSB monitored and mandated business. Lots of the fixes that we call recalls here are actually just TSBs, still done free and often quite important, but will never show up as a true recall.
I will use 2 TVS zener diode (1 for Can_H; 1 for Can_L; both Anode(+) wire to ground). I will install it for Dash, ECU, ABS, BBS then I will test the transient voltage ! I have checked all relays, regulator, alternator; they're ok ! But now I wonder about Fan of radiator, they're brush motor which make a lot of transient voltage, but they did not used relay, they connected directly to BBS, then make a lot of noise to can bus system !
I have a 2013 hyperstrada with 10k that has never given me a problem ever.
last week I went for canbus recall and I'm having problem starting the bike in the morning. it turns on for a sec or two and dies, I have try give it few tries before it eventually starting.
yesterday while I was cracking it up the neutral light disappeared and it took while before I figure it out why was not even responding....weird
I called the dealer and of course first thing he said while being defensive was that my battery is almost dead.
any suggestions what maybe going on ?
How do you find out about these? I put my VIN on Ducati's website and it didn't return anything.
It's been repeated here at least a hundred times: These are not recalls, they are TSBs. Something Ducati does not publish to the public, only to their dealer network. Call your dealer and ask them to check on your VIN.
Yes, and by "public" you mean "People who bought the bike". Clever policy: Find out on a forum, or every 9000 miles if you take your bike to a dealer. Now that's customer service!

My dealer called me as soon as the recall was issued.
I wish Ducati will cooperate with Japanese electronic companies in the future. Now, our big problem seem 90% is about ignition coils, but in some cases, replaced the coils has not solve the problem ( like Snowcat)
All the CANBUS filter is is a small TVS diode or choke designed to prevent electrical spikes from reaching the TJA1040T component (we think) on the dashboard, which controls CAN communications. It connects to the CAN-Hi, CAN-Lo, and CAN-Gnd of the dashboard. For some reason, our bikes do not have adequate filtering and there are large electrical spikes on the main power, ground, and some signal lines, possibly caused by the coils. My guess is inadequate shielding or insulation on the coils which sends some of the high voltage spark pulse into the low voltage control circuit.
Without the filter, over time the CAN controller chip is broken down since it's only rated for 5V or so. It could happen at 1,000 miles or 20,000 miles or never, depending on manufacturing variations and the severity of the voltage spikes on your particular bike.
No wires are cut for the installation, so no worries there. The only thing they cut is some rubber insulation around the harness, and then the filter wires plug-in and are heat shrinked to prevent them from coming apart. It shouldn't have any effect on fueling and you shouldn't notice a difference after the filter is installed.
This canbus repair does relate to the coils - those spikes affected the cpu - the coils relate to the cpu. In truth, the coil thing isn't very common, and ducati did good faith repairs. Generally it's a solid reliable machine.
