9. Automatic Transmission Operation Inspection
Disconnect the angle sensor 3P (Black) connec-
tor.
Measure the resistance at the angle sensor con-
nector with the sensor installed in the crankcase.
Connection: Yellow/blue (+) Green/yellow ()
Check angle sensor resistance and turn the
reduction gear in the direction as follows:
0.8 k
Ω
or below (locked at lower side): Turn
counterclockwise
1.2 k
Ω
or more (locked at high side): Turn
clockwise
REDUCTION GEAR
Remove the control motor
(page 24-43).
If the ball nut locks up, try to rotate the motor
shaft joint in the crankcase to move the ball nut.
· The ball nut of the automatic transmission
unit can strike the shaft end and lock up. This
is just a temporary symptom. In this case, be
sure that the motor shaft joint turns smoothly
after releasing it and recheck the indicator
blinking after erasing the problem code.
