NOTICE

• Check that the pulse is felt in the brake le-

ver, brake pedal, and again in the brake le-

ver, in this order.

• If the pulse is felt in the brake pedal before

it is felt in the brake lever, check that the

brake hoses and brake pipes are connected

correctly to the hydraulic unit assembly.

• If the pulse is hardly felt in either the brake

lever or brake pedal, check that the brake

hoses and brake pipes are connected cor-

rectly to the hydraulic unit assembly.

12.Turn the main switch to “OFF”.
13.Remove the Yamaha diagnostic tool from the

Yamaha diagnostic tool coupler, and then in-
stall the protective cap.

14.Turn the main switch to “ON”.
15.Set the start/engine stop switch to “

”.

16.Check for brake fluid leakage around the hy-

draulic unit.
Brake fluid leakage



Replace the hydraulic

unit, brake hoses, and related parts as a set.

17.If the operation of the hydraulic unit is normal,

delete all of the fault codes.

EAS30202

CHECKING THE ABS WARNING LIGHT

After all checks and servicing are completed, en-
sure that the ABS warning light goes off by walk-
ing the vehicle at a speed of faster than 10 km/h
(6.3 mi/h) or performing a trial run.
