R1200RT Instrument Cluster Blank

Hi all, hello Wayne.
You're right. On R1200 04-13, BMS-K is the gateway. All ECU's are on the same lines and when one is sending it's informations, all others are on reception.
So, if one of this modules in this network is out of order, all remaining do the best to work.

Thanks for the update guys.
While I thing it is still something simple like corrosion, he has sourced and bought a ZFE from ebay.
There was a posting on the ADVrider forum, whereby a chap had sourced a ZFE which was from a different model to the bike he was working on. He connected it up and while it worked there were faults registered. These seemed to be more to do with the different donor model configurations than anything else.
Is it therefore reasonable to expect a ZFE from the same model, with similar accessories, to be able to be fitted without the need for a re-code?
Just found out that the ZFE is from the same year and model bike (but it had ESA, which Graham's doesn't).
Schuppi, i'll pass your information on, thanks.

Hey all - I am the guy with the half dead R12RT - firstly thankyou all for taking the time to try and help me work this out.
Jughead with your knowledge of the 1200RT instrument cluster - there is a cable that goes from pin 22 on the ZFE to pin 5 on the cluster which I reckon is a switched supply and I think the switching is caused by the ZFE getting an input on pin 26 from the main ignition switch. Do you know if the input to the cluste at pin 5 is a 12v supply ? Pins 1 & 2 are canbus, pin 3 permanent 12v and pin 4 ground. If I know it is supposed to be a 12v dc switched supply then I could link pins 3 and 5 to see if that causes the cluster to display again. Obviously I don't want to do this is if the input to pin 5 is say only 5vdc (although I think this unlikely).
I don't believe the cluster is faulty because when I ask the GS911 to do an instrument ECU check it reports back with no errors (see below).
However, When I ask it to complete the cluster and output tests - no errors are generated but the display remains lifeless. I have had the display apart, there is no evidence there has ever been any water ingress to the case and the pins are bright and clean.
My thoughts are that the ZFE is not switching on or has an internal issue and is not sending an output on pin 22 to tell the cluster to switch on and thereby display, but the permanent live to the cluster still allows the canbus to request the ECU info.
When I ask the GS911 to check the ZFE it reports there is no response, this again leads me to suspect that it is not switching on.
The GS911 also interrogates the ABS with no issues, but if I deliberately remove the supply to the ABS at pin 10 then the GS911 returns the same fault message I see with the ZFE. So this again points to a ZFE fault.
Now the other thing that's puzzling me is when you turn the ignition on the ABS should run through its normal self check - which it is not doing. According to the wiring diagram there is no link between the ABS and the ZFE apart from the canbus. The ABS also has a switched ignition supply which is shared with the ZFE. That's why I looked into the ignition switch this afternoon and checked out the wiring to all three locations and found no issues. It all seemed to make sense apart from the fact that the same ignition supply starts the bike - which it does with no issues, but I checked out all the cabling anyway.
Is it possible that the ABS waits for a command from the canbus to tell it to complete its self checks ?

Hi Greyscout,
Welcome to the GS-911 forum.
Hopefully the guys will chip in again to get the RT sorted.

Hello all,
I think that this wire on connector 5 (instrument cluster) is the wake-up line.
Measuring a 5V level will be possible, but have not to be permanent. It will be mensurable
with a oscilloscope.
