I've got a 2009 R12GS. The left front turn signal lamp is not working, and I'm a bit stumped as to the cause. The left bulb works when inserted in to the right turn signal, so it is not the bulb. The dash indicator and rear light illuminate, so it is not the switch. As far as I can tell they eliminated the individual fuses due to the CAN bus. Could it be some strange CAN bus behavior? Any suggestions on what to try next are appreciated.

Thanks,

Welcome to the forum.

First of all, forget about the CAN-bus. In spite of the fact that it is blamed for everything and anything it is only a bunch of wires that the various controllers use to talk to each other. Nothing that you directly interact with -- switches, levers, lights, etc. -- have anything to do with the CAN-bus.

If the other blinkers are working your handlebar switch is fine. That leaves the ZFE (central chassis controller) which actually blinks the lights, the wiring to the troublesome blinker, or the mechanical connection.

I'd start by looking at the mechanical connection, making sure that you're getting a good mechanical contact to the bulb. Then I'd get out a multi-meter and see if voltage is being applied to the socket. If not I'd start tracing the wires back from the socket, looking for a place where they may be open or shorted.

But my bike is not under warranty. An '09 is, no? In your case I'd take the bike to the dealer and say "fix!".

Good luck.

Welcome tegel.

You have got three options: either follow Marc's advice, who is undoubtedly the ueber guru on the technical side of things. I usually don't understand most of what he explains, coz' I don't touch the bike. That is for the mechi to do. I ride.

Secondly: go faster than anybody else, so you don't need an indicator.:D

Third of all: sell the bike to South Africa - the concept of indicators is an alien one.......:D

left turn indicator do not work.

Good day all

I'm new to the forum but not new to biking.
i have a R120gs 2006 modul
Problem I'm having looks like one that happens allot!!!:mad:
Left front rear indicators do not work no dash indication either.:confused:
what i have done is to check the globes they are ok. i activated the left indicator and tested for voltage 0vdc.
i also checked the conection( plug ) in die left handle bar unit could not see anything wrong

did anyone else sort out the issue and what was it.:)

regards

Hello Reinhardt

There is a subminiature switch in the left switch plate. This component won't
work. Usually the rubber gasket of this switch is damaged and there is an invasion of water.:(
Either a new one or disassemble and try to clean it. Just as well, you can mount a used switch.

hi

see attached photos.:eek:

I took off the LHS switch assembly and tested the micro switch for the LHS indicators.. when pressing the micro switch the continuity do not measure zero ohms. ( 680 ohms) i believe that it should measure 0 hms as soon as the contact closes can any body confirm this?:(

Micro switch is sealed with what looks like resin so to open and try and clean it will be a tidies job
I don't know if this a good idea. but I will try any:eek:ways as it is already stuffed up.

Does any body know where I could purchase a unit like the one attached in the photo and what would the price be? I'm based in Middelburh MP South Africa. or should this be done at my local BMW shop:cool:

also another question: the heated grips can only be replaced as a unit and to me it looks like the rubber part is not interchangeable. :confused:

Beemer boneyard in the US might have a used unit, but I don't know if they ship to South Africa. As you discovered the switches in the unit are not really fixable or replaceable.

What many have done with worn hand grips that are otherwise still working (the heated portion) is to cover instead of replace. I used grip buddies on my '05. Others have wrapped the grips in O-rings, tennis racquet tape, bicycle handlebar tape, etc.

Problem with blinkers

Hey guys...i'm not gonna open a new topic since this one has similar issues so i think it's best to keep em in one place.
I have 2004 GS1200 and since yesterday an odd error.
When i turn on the bike right side blinkers turn on immediately and start blinking all by themselfs and i can't turn 'em off or turn on left blinkers.
Then when somehow after pressing it for many times i get all four to work then i can turn off all four together, but then left side works normally (turns on on a switch and off on cancel switch) but right side is not responding at all.
Then after few minutes right side turns on again and it's the same thing all over again.

Same when i turn ignition off and start it up again, just starts from square one described above.
Anyone had this problem or knows solution?
