HYDRAULIC UNIT OPERATION TEST
The reaction-force pulsating action generated in
the front brake lever and rear brake lever when
the ABS is activated can be tested when the ve-
hicle is stopped.
The hydraulic unit operation can be tested using
the following two methods.
• Brake line routing confirmation: this test
checks the function of the ABS after the sys-
tem was disassembled, adjusted, or serviced.
• ABS reaction-force confirmation: this test gen-
erates the same reaction-force pulsating action
that is generated in the front brake lever and
rear brake lever when the ABS is activated.
Brake line routing confirmation
WARNING
EWA13120
Securely support the vehicle so that there is
no danger of it falling over.
TIP
• For the brake line routing confirmation, use the
diagnosis of function of the YDT.
• Before performing the brake line routing confir-
mation, make sure that no malfunctions have
been detected in the ABS ECU and that the
wheels are not rotating.
1. Place the vehicle on the centerstand.
2. Push the OFF/LOCK switch.
3. Remove:
• Battery cover
Refer to “GENERAL CHASSIS (1)” on
page 4-1.
4. Check:
• Battery voltage
Lower than 12.8 V

Charge or replace the
battery.
TIP
If the battery voltage is lower than 12.8 V, charge
the battery, and then perform brake line routing
confirmation.
5. Removing the protective cap, and then con-
nect the YDT to the YDT coupler.
Refer to “YDT” on page 9-3.
TIP
• Yamaha diagnostic tool (A/I) (90890-03264) in-
cludes YDT sub harness (6P) (90890-03266).
• If you already have Yamaha diagnostic tool (A/
I) (90890-03262), YDT sub harness (6P)
(90890-03266) is separately required.
6. Start the YDT and display the diagnosis of
function screen.
7. Select code No. 2, “Brake line routing confir-
mation”.
8. Click “Actuator Check”, and then operate the
front brake lever “1” and rear brake lever “2”
simultaneously.
TIP
• The hydraulic unit operates 1 second after the
front brake lever and rear brake lever are oper-
ated simultaneously and continues for approx-
imately 5 seconds.
• The operation of the hydraulic unit can be con-
firmed using the indicator.
On: The hydraulic unit is operating.
Flashing: The conditions for operating the hy-
draulic unit have not been met.
Off: The front brake lever and rear brake lever
are not being operated.
