Hi all,

This is a tuto on how to plug a quadlock charger or any charger on a F800ST, S, R.

This method is to avoid a constant live USB cable draining the battery by using the spare CAN BUS plug next to the battery which is their for the optional GPS.

Materials:

- Adapter cable from CAN BUS to anyhting:

You can get one from BMW shop too

- 12 V to 5V converter

Can be found on Amazon too

- A quadlock charger or any charger

Installation:
  1. Couple the CAN BUS adapter to the 12V converter
  2. Remove the battery cover and the right top fairing
  3. Untie the spare CAN BUS plug situated on the right side of the battery, remove the cap
  4. Route the cable from handle bars to the CAN BUS using the clutch cable route. Under the frame, back up outside the frame on the right attached to the front subframe bolt next to the liquid cooled tank. Secure with zip ties along the way ensuring the cable does not tense when turning lock to lock
  5. secure the converter and extra cable on the right of the airbox

Voila!

It is a bit costly but very neat and it is great not to have to worry about draining the battery

Don’t hesitate if you have any questions

None of this has anything to do with the CAN-bus. A popular misconception that has led to the misuse of the term.

Best get in contact with BMW Motorrad and explain to them the apparent error of their ways :-

Yes vendors are largely responsible for the incorrect usage of the term. As explained in the post that I linked to it was a poor choice of identifying whether the electrical management was being done by a ZFE by citing the CAN-bus. For a better understanding of what the CAN-bus actually is check out the Wikipedia article on the subject.

Been a long time since I was trained but, I've still got a decent appreciation of the different layers in the OSI model of Networks. As such I think I'll skip Wikipedia this time thank you.

What is important however, is the time and effort that the OP took to write up about his experience for the benefit of others. Seems a shame to be critical on terminology used given the effort he put in.

Ride safely.

It is also important that those reading the post and wanting to do further research or reading be alerted to the factual errors lest they be led down the rabbit hole of misinformation. Looking for related material that uses the correct term "ZFE" is much more likely to yield accurate and useful results as those using the correct terms are likely to be more knowledgable.

Ok I do not understand what is the purpose of your intervention there? Like who cares? This is about adding a 12V cable on your bike. So you can enjoy a ride with your phone plugged without ruining the loom or draining the battery.
Maybe there is another blog for deep Can Bus nerds such as you that you can participate in?
Also touratech calls it a can bus plug. Why don’t you take it to them? Maybe you can advise then on their marketing….

That's exactly the problem. Marketing people started using incorrect terminology and popularized it. That doesn't make it correct just a popular misconception. If one is going to offer technical advice one should call components by their proper names. The purpose of the intervention is to alert readers to the misinformation so that they may be better informed and better equipped to understand how the electrics in their motorcycles actually function.

Yeah but...CANBUS sounds easier to remember than 'ZFE' or ''Zentrale Fahrgestellelektronik', which is specific to BMW motorcycles. I don't know what these modules are called on Audis, Mercedes, VWs... But they most likely connect these onboard processors via a CANBUS and most likely use 'electronic' fuses.

ON my F700GS the ZFE's electronic fuse declares a LMP error if the amps drawn by the headlight bulb is below ~1.5A. In case of a LED, a parallel shunt resistor of ~40 Ohm would correct that.

Yes the processors are connected together via the CAN-bus yet we do not refer to the following processors as "CAN-bus" do we?

The Kombi/instrument cluster.
The BMSK/engine management system.
The DWA/alarm system.
The RDC/tire pressure monitoring system.

So why would we refer to the ZFE as "CAN-bus"? Or would you prefer to just call everything "CAN-bus" because it is easier to remember?

We could say:
The CAN-bus says I need gas.
I remapped the CAN-bus and the engine runs much smoother with the new exhaust.
Someone moved my bike while parked and the CAN-bus alerted the neighbours.
I had a slow leak but the CAN-bus alerted me before the pressure got too low.

😂

Yeah and you pointed it out clearly as 'Marketting'. I just tried to find a H7 LED for my F700GS on Amazon and Ebay and the term "CANBUS" is abused allover there.

Too late to correct it! But you can keep up the fight, ahem the education! :)

Exactly. When you have an issue with your bike searching using the term "CAN-bus" yields a lot of posts that are of questionable validity but if you search on terms like "ZFE", "BMSK", "DWA" and "RDC" you are much more likely to find accurate information that will be of assistance. No need to join the herd headed in the wrong direction.
