17-122 SELF-DIAGNOSIS SYSTEM
KIBS Service Codes
Front Wheel Rotation Sensor Wiring Inspection
(Service Code B43)
Disconnect the front wheel rotation sensor lead connec-
tor [A] (see Front Wheel Rotation Sensor Removal in the
Disconnect the KIBS hydraulic unit connector (see KIBS
Hydraulic Unit Removal in the Brakes chapter).
Check the wiring continuity of the W/BK lead and BK/W
Front Wheel Rotation Sensor Lead Connector [A]
KIBS Hydraulic Unit Connector [B]
W/BK Lead Terminals [C]
BK/W Lead terminals [D]
If the wiring is open, replace or repair the harness (see
KIBS System Circuit in the Brakes chapter).
If the wiring is good, go to next step.
Perform the Pre-Diagnosis Inspection 1 and 2 (see In-
quiries to Rider in the Brakes chapter).
If this service code appears even if all checks are ended,
replace the front wheel rotation sensor (see Front Wheel
Rotation Sensor Removal in the Brakes chapter).
Still, when it is not good, replace the KIBS hydraulic unit.
If the service code does not appear, the KIBS system nor-
mal (temporary failure).
Rear Wheel Rotation Sensor Signal Abnormal
(Service Code B44)
Measure the air gap between the rear wheel rotation sen-
sor and sensor rotor.
Thickness Gauge [A]
0.4 ∼ 1.6 mm (0.02 ∼ 0.06 in.)
If the measurement is not the standard, adjust the air gap
with the spacer.
0.5 mm (0.020 in.)
1.0 mm (0.039 in.) (STD)
1.5 mm (0.059 in.)
If the air gap can not be adjusted by spacer, check each
part for deformation and looseness and correct accord-
If the measurement is the standard, go to next step.
