     *: The mode of “Low voltage ABS” controls ABS while reducing the load to the battery.

                                                    NOTE
    ○When the yellow ABS indicator light (LED) is blinking, the ABS has been in the low voltage mode
     (insufficient battery voltage). When it is in the low voltage mode, the KIBS system does not func-
     tion, but the ABS functions. To recover the KIBS system, charge the battery. (see Refreshing
     Charge(16-30)).

ABS Hydraulic Unit Removal
                          NOTICE
    The ABS hydraulic unit [A] has been adjusted
    and set with precision at the factory. Therefore, it
    should be handled carefully, never struck sharply,
    as with a hammer, or allowed to fall on a hard
    surface.
    Be careful not to get water or mud on the ABS hy-
    draulic unit.

•○Drain the brake fluid from the front and rear brake lines.
  Drain the brake fluid through the bleed valve by pumping
    the brake lever and pedal.

• Remove:
   Rear Fender (see Flap and Rear Fender Removal(15
     -28))
     Brake Hose Lower Ends (see Brake Hose and Pipe Re-
     placement(2-44))
•   Clean the ABS hydraulic unit.
                          NOTICE
    Clean all fittings on the ABS hydraulic unit and the
    rear master cylinder because dirt around the banjo
    bolts could contaminate the brake fluid in the line
    during removal/installation.
    Spread over a shop towel around the ABS hydraulic
    unit before removing the brake line so that brake
    fluid does not leak on the parts.
