FIP-1.57 042-326: IOT Sub Motor Failure

Step
Possible causative parts:
DRIVE ASSY SUB (PL7.1.1)
PWBA MCU (PL8.3.6)
HARNESS ASSY SUB MOT MG AIO (PL9.1.8)
Does the error still occur when the power is turned OFF and
1
ON?
Checking after resetting the FUSING UNIT and PHD ASSY
Reseat the FUSING UNIT and PHD ASSY.
Warning: Start the operation after the FUSING UNIT has
2
cooled down.
Does the error still occur when the power is turned OFF and
ON?
Checking the Sub Motor for rotation.
Does the Sub Motor function normally?
- PC Operation :
3 Checked by [Fuser Motor Operation Check] of the [Machine
Check] in Tool Box.
- Panel Operation : Checked by [Digital Output] - [Sub
Motor] of [IOT Diag] in diagnosis.
Checking the connectors of the SUB MOTOR for
connection.
Check the connections between the PWBA MCU and
DRIVE ASSY SUB.
Are P/J22 and P/J221 connected correctly?
4
Does the error still occur when the power is turned OFF and
5
ON?
Checking the HARNESS ASSY SUB MOT MG AIO for
continuity.
6 Disconnect J22 from the PWBA MCU.
Disconnect J221 from the DRIVE ASSY SUB.
Is each cable of J22 <=> J221 continuous?
Checking after resetting the DRIVE ASSY SUB.
Reseat the DRIVE ASSY SUB.
7
Does the error still occur when the power is turned OFF and
ON?
Checking the power to the DRIVE ASSY SUB.
Disconnect J22 from the PWBA MCU.
8 Are the voltages across J22-2pin/J22-4pin <=> ground on
the PWBA MCU, about +24 VDC when the interlock switch
(HARN ASSY INTERLOCK AIO) is pushed?
