Continuity check of HARNESS ASSY MAIN
Disconnect P/J410 from PWBA MCU and P/
J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J410-5 ↔ J502-5
J410-6 ↔ J502-6
J410-7 ↔ J502-7
J410-8 ↔ J502-8
Replace LV/
HVPS. (p.407) Repair broken
or shorted part.
24 Operation check of CLUTCH ASSY REGI
Does CLUTCH ASSY REGI operate
normally?
Make a test print and confirm by the operating
noise.
Go to Step [28] . Go to Step [25].
25 Continuity check of HARNESS-ASSY P/H1
Disconnect the P/J408 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J408-3 ↔ J603-10
J408-4 ↔ J603-9
Go to Step [26] . Replace
HARNESS-
ASSY P/H1.
26 Continuity check of HARNESS-ASSY P/H2
Disconnect P/J603.
Do all of the wiring below have normal
continuity?
P603-3 ↔ P203-2
P603-4 ↔ P203-1
Go to Step [27] . Replace
HARNESS-
ASSY P/H2.
27 Check of resistance value of CLUTCH
ASSY REGI
Disconnect P/J203.
The winding resistance between the terminals
of CLUTCH ASSY REGI is 144Ω ± 10%
(20°C)?
Go to Step [22] . Replace
CLUTCH
ASSY REGI.
(p.329)
Step Check Yes No
28 Check of 24 VDC power supply to
MOTOR-PH
The voltage of P409-6 ↔ P409-5 on PWBA
MCU is 24 VDC?
Go to Step [29]. Go to Step [22].
29 Continuity check of HARNESS-ASSY P/H1
Disconnect the P/J409 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J409-1 ↔ P604-6
J409-2 ↔ P604-5
J409-3 ↔ P604-4
J409-4 ↔ P604-3
J409-5 ↔ P604-2
J409-6 ↔ P604-1
Go to Step [30]. Replace
HARNESS-
ASSY P/H1.
30 Check after replacement of MOTOR-PH
Replace MOTOR-PH. (p.337)
Does the error recur when a test print is made?
Replace PWBA
MCU. (p.404) End of
procedure
Step Check Yes No
