Hello...this is a result of the Christmas Tree light issue on my 2013 Hyperstrada. I have my ECU, Dash and BBS at Carmo for the 2nd time (1st time didn't work). They have told me to check and replace the CAN bus resistors at the termination points....where are these? I don't see any resistors at the ECU, Dash or BBS plugs.....what am I missing or looking for?
The termination resistors will probably be built into components. The can hi and can lo system use a grey/green and grey/black wire from the BBS to the dash and spurring off to the ECU. You could trace the wires but the termination will probably occur inside the component. I know a good dash expert in Australia. If you check ‘Riderlogic’ (Wayne) on Facebook. Alternatively, there is Mark at Scorpio Electronics in the UK.
Excellent info..... Thank you. I thought it might be the case with internal termination points. I guess it should be fairly easy to verify..... I'll measure canH to canL resistance without the dash and BBS. Then again with the components attached and see when it's close to 60 ohms.
There was a recall on some of the Hypers to install a diode into the wiring to protect the CAN. I've seen a few knock out the dash and ECU. It would be wise to check if it's been done. Your dealer should be able to tell you.
Yup .. I had the can filter installed and it still took out the ECU in August. I replaced it again while waiting for my repaired components to be returned. I also swapped out the beru coils which I believe is the root issue. All around, it's a crappy deal with limited dealer support (I tried).
You need to swap Beru coils for the Eldor ones of an 848 and you need to make sure this part is fitted into the wiring behind the dash. if that’s not wired into the loom between the dash and its connector it will just happen again. These photos were taken off a bike that had already supposedly had the issue sorted. The dash had been sent away to be repaired but whoever did it, just changed the Beru coils for newer Beru coils with a different letter suffix at the end of the part number and they didn’t fit the can bus filter. As a consequence it blew again. Unfortunately for this customer it took out the canbus node in his ECU too so he had to pay for Carmo to repair both his dash and his ECU.
BTW... What's the damn secret to installing the can filter into the dash plug? That job sucked. I would have saved time of time by cutting and soldering vs trying to rewire the plug!
It’s easy. There’s a lock on the multi pin plug, release it and all the ons can be pulled out with your fingers. Slip the filter in between the removed pins and the plug and re-lock the plug.
This is the plug that goes into the dash. push this white tab inwards with a screwdriver. the two smaller white tabs on the other side will now protrude. and you can now pull the wires you need access to out from the back. you need to pull out wires for pins 10 & 11 and wire 6, colours are on the wiring diag above. This is the kit you can buy. The wires you pulled out plug into the 3 female connectors of the kit and the male connectors plug into the big plug. The colours of the wires on the kit are the same as those the loom. once they’re in situ push the 2 white locking lugs back place. If they won’t go don’t force them it’s just that you haven’t pushed the new connectors far enough in. The shrink wrap in the kit is useless, wrong size, use your own shrink wrap over the joined connectors and then tidy it all up with tape.

I struggled to pull out just the wires I needed and ended up pulling them all. Then, installing them 1 by one.... Sucked.
As a rule of thumb, you should never cut and/or solder into either of the can bus cables. The voltages are low and super sensitive to the signal strength. The cut or solder can introduce a resistance and that's the end of your canbus...
So you worked out that the two white lugs are a locking mechanism for the pins? You do not pull them out. Instead you use an extractor tool to push them out from the other side. You can obtain cheap extractor tool kits off ebay that will allow you to work with a multitude of connectors.
