Is there a Jumper fix for the Gen 3 bikes to activate the ABS?
After confirming that the test plug was wired correctly and I was shorting the sky blue and black wires, I went back and tried the first test (which, according to the Service Manual, is needed only if the unit has been disassembled). It worked exactly as described. So I went back to the second test and varied some of the inputs. Turns out it works even if the ABS light is flashing, provided I make a definite pause between releasing the starter button and applying the brakes.I couldn't get this to work on my '06. The connector is exactly the same, and I had no trouble identifying the pins that are connected to each other in the photo. When I turned on the ignition (with the kill switch set to off) the ABS light would not stop flashing. I checked the battery voltage as the Service Manual recommends, and it was fine. Connecting a charger pushed the voltage even higher, but the ABS light kept flashing. I even tried doing the test but nothing happened, as the Manual predicted when the light is flashing. The light went off as soon as I removed the alligator clamp connecting the pins.A few pics of my '07, location and an alligator clip to connect 2 pins to test ABS -> https://www.dropbox.com/sh/b4u2kjtylkzzuvd/AAAz_JO84kT1IemSDFBaENiDa?dl=0
The ABS was working a few hundred km ago (I test it occasionally). I could go out and test it again to make sure it's working and to cycle the fluid, then do another brake fluid flush. But I wasn't planning on insuring the bike for a few weeks, and it would be nice to finish the job before cleaning up the mess.
Suggestions, other than a defective ABS unit?
