Suzuki GSF650 Service Manual

4E-15 ABS:
Pre-diagnosis Inspection
B817H24504002
The mechanical and hydraulic components of the brake
system should be inspected prior to performing any
electrical checks. These inspections may find problems
that the ABS could not detect; thus, shortening repair
time.
Brake
Brake fluid level check
Refer to “Brake System Inspection in Section 0B
(Page 0B-18)”.
Brake pad inspection
Refer to “Brake System Inspection in Section 0B
(Page 0B-18)”.
Brake fluid circuit air bleeding
Refer to “Air Bleeding from Brake Fluid Circuit in Section
4A (Page 4A-5)”.

CAUTION
!
• The standard tire fitted on this motorcycle
is 120/70ZR17M/C (58W) for front and 160/
60ZR17M/C (69W) for rear. The use of tires
other than those specified may cause
instability. It is highly recommended to use
a SUZUKI Genuine Tire.
• Replace the tire as a set, otherwise the
DTC “25” (C1625) may be stored.
Wheel
Refer to “Front Wheel Related Parts Inspection in
Section 2D (Page 2D-6)” and “Rear Wheel Related Parts
Inspection in Section 2D (Page 2D-12)”.
Battery
Battery voltage inspection
1) Turn the ignition switch OFF.
2) Remove the seat. Refer to “Exterior Parts Removal
and Installation (GSF650/S/A/SAK7) in Section 9D
(Page 9D-6)”.
3) Measure the voltage between the (+) and (–) battery
terminals using the multi-circuit tester.
If the voltage is less than 12.0 V, charge or replace
the battery and inspect the charging system. Refer to
“Battery Runs Down Quickly in Section 1J (Page 1J-
2)”.
