ABS Servicing Precautions
There are a number of important precautions that should
be followed servicing the ABS system.
This ABS system is designed to be used with a 12 V
sealed battery as its power source. Do not use any
other battery except for a 12 V sealed battery as a power
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 system is not influenced
by electric wave radiated from the antenna. Locate the
antenna as far as possible away from the ABS hydraulic
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.
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.
Do not ride the motorcycle with air in the brake line,
or the ABS could malfunction.
