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)Information for Coolant
To protect the cooling system (consisting
of the aluminum engine and
radiator) from rust and corrosion, the
use of corrosion and rust inhibitor
chemicals in the coolant is essential. If
coolant containing corrosion and rust
inhibitor chemicals are not used, over
a period of time, the cooling ...
Spring Plate Free Play Measurement
Insufficient clutch free play will cause the engine braking
effect to be more sudden, resulting in rear wheel hop. On
the other hand, if the free play is excessive, the clutch lever
may feel “spongy” or pulsate when pulled.
Hold an extra drive shaft in a vise and install the following

Tire Tread Wear Inspection
As the tire tread wears down, the tire becomes more susceptible
to puncture and failure. An accepted estimate is
that 90% of all tire failures occur during the last 10% of tread
life (90% worn). So it is false economy and unsafe to use
the tires until they are bald.
Measure the tread depth a ...
