You WILL show a fault on ANY plug/socket disconnection, & these will be logged in the ECU memory & be flagged up upon hooking up to the GS911.
Try pulling all the engine plugs & switching on, then you will see them on the tool.
You my be able to help me here, on 2 of my C1's the diagnostic plug that has to be removed to fit the GS911, there is a loop-wire connecting 2 of the pins, this is visible from the outside,
these 2 bike have ABS, all the other C1's do NOT have this jump-wire, there is nothing connected to the blanking-plug, these bikes DO NOT have ABS.
Can you guys out there check & see if your bikes have this loop-wire?
>However I could'nt produce any fault for ABS Try disconnecting the plug/socket from the sensor, it should flag up the fault.
