10. ELECTRIC MECHANISM
Error status #5 Error code appears on the display when the foot switch is depressed.
Probable causes
1. If “E130”, “E131” or “E132” is
displayed, there is a poor
connection of the synchronizer.
2. If “E130”, “E131” or “E132” is
displayed, there is a poor
connection of the upper shaft
motor.
3. If “E130”, “E131” or “E132” is
displayed, there is a blown fuse.
Check/repair/adjust
Parts to be replaced
Refer to inspection #2-4.
Check the connection of the relay connector
between the upper shaft motor and the motor
PCB.
a. Remove fuses F1 and F2 from the motor
PCB and check the continuity.
OK if there is continuity.
GFUSE10A-250V
(10A-250V)
b. If fuse F1 of F2 is blown, check the
resistance values between each pin of the
relay connector between the upper shaft
motor and the motor PCB and between each
terminal of the fuses.
OK if ∞ ohms.
4. If “E130”, “E131” or “E132” is
displayed, there is a malfunction of
the motor PCB.
131
c. If the fuses blow again after they are
replaced, replace the motor PCB.
Motor PCB assembly
a. Check the synchronizer input while referring
to “3-7. Input checking method”.
OK if the signal turns on and off.
Resolver stator 430 assembly
b. If step a (above) is OK, there is a
malfunction of the motor PCB.
