077-301 Left Hand Interlock Open RAP
BSD-ON:1.3/1.4
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 2.6).
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 [077-300 L/H Cover Interlock Switch]. Open and close the L/H
Cover Assembly. The display changes.
Y N
Check the connections between the MCU PWB and the L.H. Cover Interlock (BSD 1.3).
Connectors are connected correctly.
Y N
Connect the connectors
Check the wire between P/J420 on the MCU PWB and the P/J135 on the L.H. Cover
Interlock for an open circuit or a short circuit (BSD 1.3). The wire are conducting with-
out 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 (PL 2.7) between P/J135 and
P/J420 (BSD 1.3). The wire are connecting successfully when the L/H Cover Assem-
bly is closed.
Y N
Replace the L/H Cover Interlock Switch (PL 2.7).
Measure the voltage between the MCU PWB P/J420-1 (+) and GND (-) (BSD 1.3). The
voltage is approx. +24VDC.
Y N
Replace the MCU PWB (PL 11.1).
Measure the voltage between the L/H Cover Interlock Switch P/J135-A2 (+) and GND (-)
(BSD 1.3). The voltage is approx. +24VDC.
Y N
Check the wire between P/J135 and P/J420 for an open circuit or a short circuit
(BSD 1.3). Repair or replace as required.
Measure the voltage between the L/H Cover Interlock Switch P/J135-B2 (+) and GND (-)
(BSD 1.3). The voltage is approx. +24VDC.
