The L/H Cover Assembly is open.
Initial Actions
• Power OFF/ON
• The L/H Cover Assembly is open.
Procedure
Check opening/closing of the L/H Cover Assembly. The L/H Cover Assembly can be
opened/closed.
YN
Reinstall the L/H Cover Assembly (PL 2.6).
Check the installation of the L/H Cover Interlock Switch. The L/H Cover Interlock Switch is
installed correctly.
YN
Install the L/H Cover Interlock Switch correctly.
Execute Component Control [071-300 L/H Cover Interlock Switch]. Open and close the L/H
Cover Assembly. The display changes.
YN
Check the connections of P/J120 and P/J405. P/J120 and P/J405 are connected cor-
rectly.
YN
Connect P/J120 and P/J405.
Check the wire between J405 and J120 for an open circuit or a short circuit (BSD 1.3 Flag
3/Flag 4).
The wire between J405 and J120 is conducting without an open circuit or
a short circuit.
YN
Repair the open circuit or short circuit.
Check the conductivity of the L/H Cover Interlock Switch (PL 2.6) between J405-1 and
J405-2 (BSD 1.3 Flag 3/Flag 4).
The wire between J405-1 and J405-2 is connecting
successfully when the L/H Cover Assembly is closed, and is insulated when the
cover is open.
YN
Replace the L/H Cover Interlock Switch (PL 2.6).
Measure the voltage between the MCU PWB P405-2 (+) and GND (-) (BSD 1.3 Flag 3/
Flag 4).
The voltage is approx. +24VDC.
YN
Measure the voltage between the MCU PWB P400-1 (+) and GND (-) (BSD 1.2 Flag
1).
The voltage is approx. +24VDC.
YN
Check the connections of P/J526 and P/J400. P/J526 and P/J400 are con-
nected correctly.
YN
Connect P/J526 and P/J400.
Check the wire between J526 and J400 for an open circuit or a short circuit
(BSD 1.2 Flag 1).
The wire between J526 and J400 is conducting without
an open circuit or a short circuit.
YN
Repair the open circuit or short circuit.
Check the connections of P/J521, P/J523 and P/J300, P/J301. P/J521, P/
J523 and P/J300, P/J301 are connected correctly.
YN
Connect P/J521, P/J523 and P/J300, P/J301.
Check the wire between J521, J523 and J300, J301 for an open circuit or a
short circuit.
The wire between J521, J523 and J300, J301 are conducting
without an open circuit or a short circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between the ESS PWB P301-3 (+) and GND (-). The
voltage is approx. +5VDC.
YN
Replace the ESS PWB (PL 9.2).
Replace the Power Unit (PL 9.1).
Replace the MCU PWB (PL 9.1).
Replace the MCU PWB (PL 9.1).
Replace the MCU PWB (PL 9.1).
