F650 GS R13 / 2000 / GS911 - BMS-C: reset adaptations for TPS / IAC not working
stardust_59:
I did the start with sidestand up and in gear, with clutch pulled as I suspected a similar interlock 'mechansim' as on the classic F650 and other bikes.
Indeed either of these conditions - sidestand down , or in gear (without clutch pulled) will prevent starting.
The bike is on the center stand, yes.
As I can see from thw wiring diagram, the Propstand switch is connected to K9110 (Motronic relay) and S9092 (Neutral safety switch) and S9091 (Clutch Safety Switch)
S9092 (Neutral safety switch) and S9091 (Clutch Safety Switch) are conneted via diode V9400 and to the propstand switch via X9380 and X9428.
Thus this setup looks pretty much like on the F650 E169 (Funduro)
I also remember , when working on the F650 CS that VIGN shows close to VBATT if the sidestand is up.
I did the ECU tests and was also able (as a test) to recalibrate the Lambda Sensor. So these items are functional.
It is only the adaptation that fails and I suspect VIGn=0 to be the reason.
All other functionality of the Engine , starting, idling etc is normal.
The reason I want to to the adaptation is that I note a very slow response of the IAC after revving the engine (to about 2000 rpm) and then releasing the throttle to idle.
The return to idle rpm is delayed and I can see in the live values that the IAC stepper shows a slow response.
It is not the throttle cable.
It moves freely and does not catch anywhere - there is enough play for the throttle to mechanically return to idle position (at the small adjuster screw)
I do have a log file of this behavior.
I will check the wiring and functionality of the prop stand, but I suspect something else to be responsible for the VIGN = 0.0V
If - VIGN = 0.0V is one of the error conditions that prevent adaptation.
Then what are the conditions to be met to perform the adaptation ?

Forget chasing Vign, you are wasting time on something which is not relevant & in terms of the BMW diagrams there are errors in the published diagrams which will lead you astray in some areas, there is some additional info on line http://www.f650gs.crossroadz.com.au/ElectricalRepairs.html
Do a reset of all adaptions then rebuild the adaptions as per the process I indicated in a post above
If you cant diagnose/start with the bike in neutral & ignition on, info on the starter lockouts is on the pages below

Wayne, thanks again for your advice.
To reiterate:
Everything works on the F650 GS
ECU - no fault codes
All ECU tests and individual actuator tests (IAC, Injector,Fuel pump, Fan) are ok. Pass. They work.
ABS no fault codes.
ABS Full bleed performed due to brake fluid change.
Brake pressure points stable.
Bike starts runs and idles stable.
All Fuses show continuity.
Dash seems ok too.
Init sequence (light show ABS, Coolant lamps) on Dash is ok as well.
Speedo works.
The only thing I cannot do is to do the adaptation reset.
Bike on main stand. Engine cold. Sidestand up. Gear in neutral. Kill switch ON. Ignition ON.
Error: conditions not met or false sequence of commands.
Perhaps GS911 SW v1807.2 ?
Might try an older version !?
I am chasing a phantom...
WayneC:
I did some quick tests on both single spark & dual spark BMSC using 1807.2 & I am unable to replicate the problem you are encountering, I am using a GS911 WiFi & USB connection which is the only real difference so I would discount 1807.2 being the issue, I even generated some fault codes to see if each of the resets failed, but they cleared the adaptions & of course the PC App gave a warning re the faults
Beyond this issue, with the dash assembly if you see any strange behaviour like ODO digits flashing when ignition is turned on dont muck about, have the 5v power rail electrolytic capacitor replaced, it will save you some grief

Wayne thanks again for having a look into the glass bowl.
I hooked up with hexcode support and sent them the GS911 logs.
No answer on said conditions or command sequence though.
They may want to keep their trade secret, which I understand.
Bike has 40k km and stood in a barn for quite a while.
I'll have a look at the wiring again and the dash will be disassembled - just to get a status on corrosion and possible vibration damage.
Dash operates ok, no flicker on the lcd display.
clock on when ignition off.
total km when ignition on.
stepper reset routine after disconnecting and reconnecting ok.
Let us see what hexcode has to say.
I followup with the solution if there is one of general interest.
Thanks again
