once locked in place, you should not be able to pull the bike connector from the GS-911 - that way you know it is connected correctly

most unlikely - we use the BMW original pins and in the whole history of each and every GS-911 we've sold, we have not had this once...

I suggest getting the wiring diagram for your bike.. it will help a lot... in the mean time...

pls get me the first 10 digits of your bike's VIN number... starting with WB1

1. disconnect the battery
2. remove connector from the Engine control unit
3. remove the connector from the ABS control unit
4. check continuity between pin1 on the bike's diagnostic connector and pin14 of the Engine ECU, to pin31 of the ABS

you should have continuity between those 3 pins... Also good idea to use a switch cleaner on the connectors, making sure they good, dry and clean..

let me know whether this helps

best,
Stephan

merlin geikie:
Thanks Stephan,

What you have given me is of great help, I am working on the bike now to test those circuits.

The VIN WB1 054 7AX 4ZG 307 77 it is a factory K1200 GT 2004 police specs with the K41 motor.

Very much appreciate your kind help here and will continue working on the bike now.

Best

Merlin

StephanT:
thanks Merlin

yes, those pinouts are correct

ABS : pin31
MA2.4 : pin14
diagnostic connector : pin1

all these are connected together and should have continuity between them

merlin geikie:
Hello Stephan,

Have carried out those plug, connector tests and found engine ecu pin 14 has continuity with pin 1 on the diagnostic plug and with pin 31 on the abs connector.

Will now test the relay and see what resistance is there.

Hello Stephan,

Just tested the abs relay (blue) and found that when 12v power was applied to pins1 and 2 then there was no continuity between pins 3 and 4.

I don't know what this means but it seemed odd that with power on the relay switched to not conductive.

Thanks again for your kind help here.
