I am sorry, I do not understand.  I can see some real time values like temperature and horn on, etc. with my GS-911. However, I cannot sniff the real time CAN buss data packets.

Hello

This is what the GS911 is designed for.
Here you can read the real-time data in the Body Controller Lite XBCL and check its functionality.

General Discussion / BMW Switchgear wiring

« Last post by tngarren on October 05, 2025, 08:08:23 PM »

2021 R18 but topic would generally apply to all CAN bus BMWs. 

I had to replace the plastic cruise control controls on the left-hand switchgear.  Like most of my work, I fixed one thing and broke another.  Now the cruise control works, however, the horn and turn signals stopped working.  The other functions on the switchgear work - cruise control, flashers, high beam, menu, aux lights. 

All the functions run off 3 CAN bus wires - 12V, CAN L, and CAN H.  They are getting 12V, 7V, 7V to ground with ignition on.  So, I am thinking the problem is on the switchgear.

I have disconnected the battery to reset the bike control units but no help. 

Is there a way to read the CAN bus data to see if the horn and turn signal buttons are sending any data?

Any other diagnostic advice is appreciated.

Pic attached.  Four circled buttons are left, cancel, right.  Bottom is horn.

GS-911 / Re: Messed Up TPM Replacement, Can It Be Saved?

if you have stored the wrong set of digits on your bike - the sensor will still wake as you ride (but you'll not know it) >40mph for a few miles is a safe bet....

then you need a spare KEY !!!   you need to get at the diagnostic socket without turning off the Key - connect up and code the correct details you should be able to see now the senor is alive - you get around 15mins from stopping the engine - I forget I think the kill switch causes the same mess up as Key off - I just stall the bike to shut the engine up and to stop it melting

GS-911 / Re: Body Controller "No response from the controller"

« Last post by dowdyphobic on September 27, 2025, 04:04:28 AM »

Just bought the GS911 and my first  AutoScan on my 2022 BMW 1250 GSA comes up with - Body Controller "No response from the controller" I tried scanning the bike with the Melon Sandbox engine on and off but still get the same error. Can anyone shed some light on this please

On 2022 R1250 GSA models the Body Controller (BDC) isn’t always accessible with GS-911 yet—BMW moved a number of functions into the BDC2 unit and support is still being updated. “No response from the controller” usually just means the tool can’t talk to that ECU, not that it’s faulty. Your bike will still scan fine otherwise. Make sure your GS-911 has the latest firmware and PC/WiFi software; if it still shows the same, it’s a current limitation of GS-911, not an issue with your bike.

R1200 models / Re: Ok, am I a complete idiot????

« Last post by dowdyphobic on September 27, 2025, 04:02:21 AM »

Just received the GS-911wifi for my 2014 R1200RT LC. It is impossible that I can see to plug the bike plug into the GS-911. Here is why: Looking inside the plug there are 3 "keys" that align the two pieces together. Two of them are toward the bottom of the plug at the 5 and 7 o'clock positions. The GS-911 has slots in the plug to engage these two "keys" (for bloodmoney lack of a better term) at the same position which is as it should be. The bike plug has another "key" at the 11 o'clock position. This is viewed with the red tab at the bottom. The simple idiotic problem is that the GS-911 has it's top slot in the 1 o'clock position. There is no way the two parts can engage.

What the hell is wrong? This is really frustrating.

Central Vehicle Electronics/ZFE/GM issues / K1200S battery going flat after a few days

« Last post by loadedtoad on September 26, 2025, 04:56:33 PM »

Hi Guys I've a problem with the bike battery going flat after a few days.
With a clamp meter attached it is always drawing 78 Miliamps.
I've removed the vehicle control module and the current drops to 5 millamp which is quite acceptable.
i can then start the bike up engine runs Ok then switch it off ,current is about 30 millamps then drops to 5 milliamps as the ECU drops into sleep mode.
Reconnect the module still only 5 milliamps.
Start bike up then switch off current stays at 78 millamps.
It would seem the control module is not dropping into sleep mode or could something be stopping it going into sleep mode ?.
No fault lights bike starts and runs fine.
No accessories complete standard bike.
Disconnect the battery bike can be left for over a month.
Not used my GS-911 for anything other than basic service work.
Is there any diagnostics on the GS-911 to watch the Can bus for activity etc to see if something is waking it up ?.
Or has anyone else had or heard of this fault ?.
Also is the vehicle control module paired to the ECU and key so i can just swap it for another unit to test .

Thanks in Advace

GS-911 / Re: Messed Up TPM Replacement, Can It Be Saved?

Thanks. I tried both wake up methods (riding and fast deflation) and neither worked. I suspect a defective sensor but I am waiting to hear from BMW about that.
Old sensor is installed in the meantime. It works but is seriously out of calibration (about 0,2 bar) but better than nothing.

One detail I omitted is I have been having problems connecting to the GS911 cloud since Monday, I always get an error message so I am really limited in what I can do now. I suspect our "Piracy Shield" is causing problems again.
