CYLINDER BLEEDING
The master cylinder has no so if bleeding is
carried out by the following procedure, bleeding of air from
the brake line will become easier. (1) Fill the reserve tank
fluid.
(2). Keep the brake pedal depressed.
(3) Have another person cover the master cylinder outlet
with a finger.
(4) With the outlet still closed, release the brake pedal.
(5) Repeat steps
three or four times to fill the inside
of the master cylinder with brake fluid.

ABS General Information
The ABS consists of wheel speed sensors, stop light switch, hydraulic unit and the ABS-ECU. If
a problem occurs in the system, the malfunctioning
system can be identified by means of the diagnostic
function.
The diagnostic trouble code will not be erased even
if the ignition switch is turned to OFF.
In addition, reading of diagnostic trouble codes,
service testing are possible using
