Rear Wheel Rotation Sensor Signal Inspection
The rear wheel rotation sensor sends the signal to the
ECU through the KIBS hydraulic unit (KIBS equipped
models). For other than KIBS equipped models, the
signal is sent directly to the ECU.
The ECU uses the rear wheel rotation sensor signal for

Piston Ring, Piston Ring Groove Wear Inspection
Check for uneven groove wear by inspecting the ring seating.
The rings should fit perfectly parallel to groove surfaces.
If not, replace the piston and all the piston rings.
With the piston rings in their grooves, make several measurements
with a thickness gauge [A] to determine pisto ...
