Anti-Lock Brake System
ABS Servicing Precautions
There are a number of important precautions that should
be followed servicing the ABS.
This ABS is designed to be used with a 12 V sealed bat-
tery as its power source. Do not use any other battery
except for a 12 V sealed battery as a power source.
Do not reverse the battery cable connections. This will
damage the ABS hydraulic unit.
To prevent damage to the ABS parts, do not disconnect
the battery cables or any other electrical connections
when the ignition switch is on or while the engine is
Take care not to short the leads that are directly con-
nected to the battery positive (+) terminal to the chassis
Do not turn the ignition switch on while any of the ABS
electrical connectors are disconnected. The ABS hy-
draulic unit memorizes service codes.
Do not spray water on the electrical parts, ABS parts, con-
nectors, leads and wiring.
If a transceiver is installed on the motorcycle, make sure
that the operation of the ABS is not influenced by electric
wave radiated from the antenna. Locate the antenna as
far as possible away from the ABS hydraulic unit.
Whenever the ABS electrical connections are to be dis-
connected, first turn off the ignition switch.
The ABS parts should never be struck sharply, as with
a hammer, or allowed to fall on a hard surface. Such a
shock to the parts can damage them.
The ABS parts cannot be disassembled. Even if a fault is
found, do not try to disassemble and repair the ABS parts,
The ABS has many brake lines, pipes, and leads. And
the ABS cannot detect problems with the conventional
braking system (brake disc wear, unevenly worn brake
pad, and other mechanical faults). To prevent trouble,
check the brake lines and pipes for correct routing and
connection, the wiring for correct routing, and the brakes
for proper braking power. Be sure to check for fluid leak-
age, and bleed the brake line thoroughly.
Air in the brake lines diminish braking performance
and can cause an accident resulting in injury or
death. If any of the brake line fittings, including the
ABS hydraulic unit joint nuts, or the bleed valve is
opened at any time, the air must be bled completely
from the brake line. If the brake lever has a soft or
"spongy" feeling mushy when it is applied, there
might be air in the brake lines or the brake may be
defective. Do not operate the vehicle and service
the brake system immediately.
Do not ride the motorcycle with air in the brake line,
or the ABS could malfunction.
