Checking method
The shift actuator can be operated in this
mode.
1. Make sure that the transmission is in
neutral.
2. Set the engine stop switch to "
operate the hand shift lever switch (shift
up) simultaneously. The MCU (motor
control unit) operates the shift actuator
once.
The shift actuator is operated once
each time two switches are operated.
3. The MCU (motor control unit) detects
the signal from the shift actuator sensor.
If the signal received after upshifting is
correct, the hand shift select indicator
light will come on.
If the signal received after upshifting in
incorrect, the hand shift select indicator
light will flash.
4. Set the engine stop switch to "
operate the hand shift lever switch (shift
down) simultaneously. The MCU (motor
control unit) operates the shift actuator
once.
The shift actuator is operated once
each time two switches are operated.
5. The MCU (motor control unit) detects
the signal from the shift actuator sensor.
If the signal received after downshifting
is correct, the hand shift select indicator
light will come on.
If the signal received after downshifting
is incorrect, the hand shift select indica-
tor light will flash.
