Traction Control System - Yamaha XRS900 Series Owner's Manual

TIP

The ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the key is turned to
"ON" and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a "clicking"
noise can be heard from the hy-
draulic control unit, and if the brake
lever or brake pedal is even slight-
ly applied, a vibration can be felt at
the lever and pedal, but these do
not indicate a malfunction.

This ABS has a test mode which
allows the owner to experience the
pulsation at the brake lever or
brake pedal when the ABS is oper-
ating. However, special tools are
required, so please consult your
Yamaha dealer.
NOTICE
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.

Instrument and control functions

Traction control system

The traction control system (TCS)
helps maintain traction when accelerat-
ing on slippery surfaces, such as un-
paved or wet roads. If sensors detect
that the rear wheel is starting to slip (un-
controlled spinning), the traction control
2
system assists by regulating engine
power as needed until traction is re-
stored.
The traction control system is not a
substitute for riding appropriately
for the conditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
turns, when accelerating hard at a
sharp lean angle, or while braking,
and cannot prevent front wheel slip-
ping. As with any vehicle, approach
surfaces that may be slippery with
caution and avoid especially slip-
pery surfaces.
