Re: din/pin
Jumper the black and blue wired pins with a wire. Stripped both ends of a awg 16 wire will snugly fit into the connector. The service manual calls for a specific Yamaha connector but the jumper wire trick works the same.
You can confirm if the jumper is connected by turning on the key and observe that the ABS lamp will flash.
To cycle the ABS, after doing the above, kill switch set to OFF, press n hold the start button for 4 secs, then simultaneously hold down both lever n pedal of the brakes. Continue holding until the ABS pump finishes its sequence which takes about 15 secs.
To remove the rubber waterproof plugs on the connector, I find that a micro screwdriver meant for spectacles, flat blade type, and of the smallest one, can do the job.
Cycle the pump once a while to move out any build up crude within the valves. Do this after bleeding the brakes. It is required per brake bleeding procedure.
