092-661 IOT Environment Sensor Error
Step Check Yes No
Possible causative parts:
• Laser Unit (PL2.1.1)
• Top Harness Assembly (PL18.2.5)
• LVPS (PL18.1.34)
• MCU Board (PL18.1.13)
1 Check the Laser Unit connection
Check the connection between the Laser Unit and the MCU
Board, and the connection between the Laser Unit and the
PWBA LVPS.
Are P/J36, P/J11, and PJ43 connected securely?
Go to step 2. Connect P/J36,
P/J11, and PJ43
securely.
2 Check the continuity between the LVPS and the Laser Unit
Is each cable of P/J43<=>P/J431 continuous?
Go to step 3. Replace the Top
Harness
Assembly.
3 Check the power to the Laser Unit (+5 VDC)
Close the interlock switch(es), and check if the voltage
between the LVPS ground and the P/J43-2 pin is about
+5 VDC.
Go to step 4. Replace the LVPS.
4 Check the power to the Laser Unit (+24 VDC)
Close the interlock switch(es), and check if the voltage
between the MCU Board ground and the P/J36-1 pin is about
+24 VDC.
Go to step 5. Refer to
“+24 VDC Power
FIP” on
page 2-222.
5 Check the power to the Laser Unit (+3.3 VDC)
Check if the voltage between the MCU Board ground and the
P/J11-1 pin is about +3.3 VDC.
Go to step 6. Refer to
“+3.3 VDC Power
FIP” on
page 2-224.
6 Check after replacing the Laser Unit
Replace the Laser Unit.
Does the error still occur?
Replace the MCU
Board.
Finished.
