Brake Bleed sequence on 2014

[RossKean]

Do you get a firm brake lever and pedal? If so, I don't think you have bubbles. Did you do anything that might have introduced air?

You bled left front and right front upper bleeder using brake lever then right front lower bleeder using rear brake pedal and then rear brake caliper?

Are you sure you are getting ABS actuation? I assume this is while riding and not testing it on the centerstand? ABS doesn't like it being used to stop the rear wheel while on the stand...

Front brake, rear brake or both?

Assume you removed the jumper from the test coupler and no chance anything shorted in there?

Only other thing I can suggest is remove and clean ABS sensors and make sure wires aren't damaged.

Same questions as RossKean. Plus: any error codes stored in the ABS computer? What is the ABS light doing?

I don't have any specific knowledge of the 2014, but earlier models used a speed sensor on each wheel plus a calculated vehicle speed to plot slip speed.

ABS wheel sensors typically generate a voltage from which the computer calculates the speed. A magnetic ring induces the voltage in the sensor. At low speeds, excessive clearance between the sensor and magnets can cause the voltage to drop off prematurely at low speeds, so the computer thinks that particular wheel has stopped rotating, or at least, slowed way faster than it should have.

Such a condition may not set an error code since the ABS thinks it is receiving a valid speed, but may if the computer realizes the wheel speed did not resume when the ABS kicked in. It depends on how close to a stop you where when the voltage dropped off -- if it's immediately before the bike stops anyway then the computer may assume the signal did not return because the bike stopped.

I have seen this happen in other vehicles when a layer of corrosion on the sensor mounting surface pushes the sensor away just a few thousandths of an inch. So if you have no stored codes and this only happens immediately before a stop, I'd look very closely at the sensors and clearances.

If it only happens on the rear brake pedal, then the rear wheel sensor is the first one I would look at. I suspect if the front sensor was suffering from this condition then both the front and rear brakes would pulse, since the ABS computer has no way of knowing if it's the front lever or rear pedal locking up the linked brakes. But I'm just guessing there. Maybe the computer has some algorithm to determine which one to actuate if the front locks.
