There are two tests listed in the FSM for the Gen II bikes. Not sure if this is true for the Gen I as well.
FSM
2014/2015 Gen II page 4-77-79 shows two tests.
Hydraulic unit operation test 1: This test checks the function of the ABS after the system was disassembled, adjusted, or serviced.
Hydraulic unit operation test 2: This test generates the same reaction-force pulsating action that is generated in the brake lever and brake pedal when the ABS is activated.
Two people are necessary to perform hydraulic unit operation test 1.
-----------------------------------------------------------------------------
1. Place the bike on the centerstand.
2. Turn the main switch to OFF.
3. Remove the rider seat, adjuster, right side cowling.
4. Verify battery voltage. Lower than 12.8v means you need to charge the battery first.
Note that if the battery voltage is lower than 10v, the ABS warning light will come on and the ABS will not operate. (I didn't know that!)
5. Bridge the pins in the test connector, (
LINK ), Blue and Black. (full write up at the link by 2daMax on a
Gen I)
6. Turn the main switch ON
while operating BOTH the brake lever and foot pedal
simultaneously.
TIP - It won't work unless both brake pedal and lever are pressed at the same time when the main switch is turned on. (note that if the ABS warning light is not flashing, the test pins are not bridged.)
Do not push the engine start/run/kill to
start when turning the key on or the test will not begin.
7. Check: Hydraulic unit operation. When the main switch is turned to ON, a single pulse will be generated in the brake lever, brake pedal and again in the brake lever, in this order.
The second person should be applying rotation force to the rear wheel to see that braking force is released for 0.1 second allowing brief rotation.
Notes: If the pulsing is felt in the order described, all is good. If it's felt in the rear before the lever, that usually means incorrectly connected lines. Unlikely for most of us.
If the rear braking force is not released briefly during the pulsing of the pedal, but is during the pulsing of the lever, again, check the lines are correctly connected to the ABS pump. Again, not likely unless you've just replaced the pump.
If everything is normal, delete error codes.
--------------------------------------------------
Hydraulic unit operation test 2.
1. Place the bike on the centerstand.
2. Check the following: Engine stop due to side stand operation.
a. shift trans into gear and extend the side stand.
b. turn kill/run/start switch to ON.
c. Push the kill/run/start switch to start and check that the starter doesn't operate. If it does, you have side stand switch issues. Sort that first.
d. Turn the main switch OFF.
e. Retract side stand.
------------------------------------------------
3. Remove rider seat, etc.
4. Check battery voltage. Must be over 12.8v. If not, charge batt.
5. Connect test coupler as before.
6. Extend sidestand.
7. Turn the main switch ON.
8. Push the 'start' side of the start/spot/run switch for at least 4 seconds.
NOTE:
Do not operate the brake lever or brake pedal.
9. After releasing the start switch, operate the brake lever and brake pedal simultaneously.
10. A reaction-force pulsating action is generated in the brake lever and continues for a few seconds.
TIP - The reaction-force pulsating action consists of quick pulses.
Be sure to continue operating the brake lever and brake pedal even after the pulsating action has stopped.
11. After the pulsating action has stopped in the brake lever, it is generated in the brake pedal and continues for a few seconds.
12. After the pulsating action has stopped in the brake pedal, it is generated in the brake lever and continues for a few seconds.
NOTE: Check that the pulsating action is felt in the brake lever, the brake pedal, and again in the brake lever, in this order.
If it's in a different sequence, something is hooked up wrong.
13. Turn the main switch OFF.
14. Remove the test coupler.
15. Turn the main switch ON.
16. Shift the trans into neutral and retract the side stand.
17. Check for brake fluid leakage around the hydraulic unit.
