077-301 Left Hand Interlock Open RAP

BSD-ON:1.2/1.3
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.
Y N
Reinstall the L/H Cover Assembly (PL
Check the installation of the L/H Cover Interlock Switch. The L/H Cover Interlock Switch is
installed correctly.
Y N
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.

Check the connections of P/J120 and P/J405.
rectly.
Y N
Connect P/J120 and P/J405.
Check the wire between J405 and J120 for an open circuit or a short circuit (BSD 1.3
3/Flag 4). The wire between J405 and J120 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
Check the conductivity of the L/H Cover Interlock Switch
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.
Y N
Replace the L/H Cover Interlock Switch
Measure the voltage between the MCU PWB P405-2 (+) and GND (-) (BSD 1.3
Flag 4). The voltage is approx. +24VDC.
Y N
Measure the voltage between the MCU PWB P400-1 (+) and GND (-) (BSD 1.2
