Checking the ACTUATOR REGI ROLL M for shape and
operation.
Remove the CHUTE ASSY LOW (PL3.2.27) once to check
the shape and operation.
Are the shape and operation of the ACTUATOR REGI
ROLL M normal?
Go to step 18.
Reseat the
ACTUATOR REGI
ROLL M. If broken
or deformed,
replace it with a

Checking the Regi. Sensor (SENSOR PHOTO) for
operation.
Does the number on the screen increase by one, when the
actuator (ACTUATOR REGI IN) is operated?

the operation.
Checked by [Digital Input] - [Regi Sensor] in [IOT Diag] of
diagnosis.
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
Go to step 26.
19
Checking the connectors for connection
Check the connections between the PWBA MCU and
DRIVE ASSY MAIN (Main Motor).
Are P/J21 and P/J211 connected correctly?
Go to step 20.
Reconnect the
connector(s) P/
J21 and/or P/J211
correctly.
20
Checking the HARNESS ASSY MAIN MOT MG AIO for
continuity
Disconnect J21 from the PWBA MCU.
Disconnect J211 from the DRIVE ASSY MAIN.
Is each cable of J21 <=> J211 continuous?
Go to step 21.
Replace the
HARNESS ASSY
MAIN MOT MG
AIO.
21
Checking the power to the DRIVE ASSY MAIN
Disconnect J21 from the PWBA MCU.
Are the voltages across J21-2pin/J21-4pin <=> ground on
the PWBA MCU, about +24 VDC when the interlock switch
(HARN ASSY INTERLOCK AIO) is pushed?
Replace the KIT
DRIVE ASSY
MAIN. (Refer to
REP7.2.)
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
