Thickness Gauge [A]
Air Gap
Standard: 0.4 
1.6 mm (0.02
0.06 in.)
If the measurement is not the standard, check each part for deformation and looseness and correct accordingly.
If the measurement is the standard, go to next step.
If the sensor and sensor rotor in bad condition, remove the any deposits. Install the proper part or replace faulty part.
If the all items are good, go to next step.
If this service code appears even if all checks are ended, replace the KIBS hydraulic unit
If the service code does not appear, the KIBS system normal (temporary failure).
Front Wheel Rotation Sensor Wiring Inspection (Service Code b 43)
Rear Wheel Rotation Sensor Wiring Inspection (Service Code b 45)Stick Coil Primary Peak Voltage Inspection
NOTE
Be sure the battery is fully charged.
Remove the stick coils (see Stick Coil Removal).
Do not remove the spark plugs.
Connect the ECU to the harness.
Measure the primary peak voltage as follows.
Install the new spark plug [A] into each stick coil [B], and
ground them onto ...
System Components
1. FI ECU
The FI ECU analyzes the motorcycle conditions based
on the signals from the front/rear wheel rotation sensors
and FI sensors (such as the crankshaft sensor and main
throttle sensor), and controls engine power by reducing the
number of ignition and retarding the ignition timing. The
