Error Troubleshooting
042-325 IOT Motor Failure
Step Check
Possible causative parts:
• Main Motor [Drive Assembly] (PL3.1.1)
• Drive Harness Assembly (PL18.2.2)
• Top Harness Assembly (PL18.2.5)
• LVPS (PL18.1.34)
• MCU Board (PL18.1.13)
1 Check the Main Motor operation
Execute Digital Output diagnostic test 071-001, and check
the Main Motor rotation.
Does the Main Motor function normally?
2 Check the Main Motor connection
Check the connection between the Main Motor and the
LVPS, and the connection between the Main Motor and the
MCU Board.
Are P/J311, P/J509, P/J171 and P/J17 connected securely?
3 Check the continuity between the Main Motor and the MCU
Board
Is each cable of P/J171<=>P/J17 continuous?
4 Check the continuity between the Main Motor and the LVPS
Is each cable of P/J311<=>P/J509 continuous?
5 Check the power to the Main Motor (+24 VDC)
Close the interlock switch(es), and check if the voltage
between the LVPS ground and the P/J509-1 pin is about
+24 VDC.
