Title: 10442: Fuse activated for component System Supply
Post by: EvilEagle on November 14, 2018, 04:00:54 PM
“Fuse activated for component System Supply” does that mean a new O2 sensor is needed or do I have a break in the wiring somewhere? Any ideas?

Will need a little more info than that.  Post your Autoscan.

OK.  That is a start.  This is going to be like pulling teeth.

What bike is it?

Sorry man, I just got the GS-911. First time using it. It’s a 2007 GS Adv.  it’s not idling unless the vacuum ports are unblocked. I’m trying to chase down what has happened. One guy mentioned the Lambda sensor so I was wondering if this error might mean it needs to be replaced. I don’t see any other errors that are obviously related.

Ok, we're getting closer.

2007 GS Adv what?  800 or 1200.  Very different bikes.  I am assuming 1200 as the 800 Adv only came later.

That is why I suggested posting your Autoscan.  What you posted was just the error in question.  One post (the FULL Autoscan) will answer all the questions.

Explain a little more about " it’s not idling unless the vacuum ports are unblocked."  Are you saying that it will only idle if you remove the rubber caps from the ports?

A faulty lambda sensor will not prevent the bike from idling.

You are right, 1200 ADV.

The full auto scan has a bunch of non related stuff (lights, fuel guage, etc) so I didn’t want to garbage up with everything.

I hadn’t ridden the bike in a while so I started on a good bit of mx. I changed the final drive fluid, checked the valve clearances and changed the oil. It had been a bit harder to start so I also changed the battery. As I put it all back together it wouldn’t idle at all without holding the throttle open. I replied to a thread in ADVrider about it. The consensus was that I had throttle cables that weren’t seated in the Bowden box. I checked those and the pulleys in the box. All is routed correctly and clean. The next thing was to sync the throttle bodies. I was not convinced that was the problem but I was out of ideas.  So I pulled the vacuum port caps off (I removed the charcoal canister years ago). For some reason i started it before hooking up the hoses to do the sync. It idled fine and rides well. (Other than the sucking sound from the ports).

I checked and rechecked the cables many times. I pulled the back side of the intake off to see if the butterfly valves were gunned up and not closing right.  Clean and good to go. It seems like I have a clog somewhere but I don’t know the intake system well enough to know where it could be. The bike has 64k miles.

Great.  1200s are relatively simple.

The first thing to do would be to clear all the faults and reset the adaptations.  All of them.

Next, turn the ignition on and allow the bike to go through its diagnostic checks until the LCD screen  "Check" diasappears.  Turn the ignition off for a few seconds, and then back on again.

Re-run the Autoscan and see whether the faults have returned.  Hopefully they haven't.

Now remove the idle bypass valves on the throttle bodies and check to see whether they are functioning correctly.  They are located here.

Once removed, clean them with some brake or carb cleaner, and check the operation.

Here is a clip of how the valve should operate when the ignition is cycled.  At ignition on the valve should retract.  At ignition off the valve should extend.

Once you are sure that they are operating correctly, refit them and again reset the adaptations.

The bike should fire up and idle without the assistance of the throttle.

Thanks!!

I’m traveling till Monday (not on the bike) so I’ll have to do that when I get back next week. Much obliged!!

Looks like I have bad bypass valves. Errors were still there and the cables barely move at all.

Which cables are you referring to?  All you need to check is whether the plunger operates as in the video posted above.  If not, replace them.

Must’ve been a strange auto correct or something. The pistons barely move.

They need to move at least as much as They do in the clip above.  If not replace them.  It is strange though that they are both failing.

Exactly what I was thinking. Both failing at once?

Maybe try swapping just one from a known good source, like your mate's bike after you have plied him with a few beers. 🤣

Update:  I got two bypass valves online. Both are doing the same thing - just barely moving when the key is turned on. What controls them? This is very frustrating!

If you don't know their provenance, try to see if you can test one of them on a bike known to be already working.

Yip, that is exactly why I said "from a known good source"

The only way to eliminate them as the problem is to determine whether they are actually faulty.

I hear ya.  I'll look for another GS in the area (don't know of anyone else who rides one here in flat-land).  The likelihood of both mine failing at the same time then both of the ones I get online doing the exact same thing?  I think that's a stretch...
