3.3.1 Fault Code FIP

001-300 L/H COVER INTERLOCK OPEN

Description The L/H COVER is open.
BSD on : CH1.7 CH1.9
Procedure
Run the DC330 [001-301].
Open and close the L/H COVER, and turn the SWITCH On/
Off.
Is the display switched between H and L?
Y N
Is +24 VDC measured between the LOW VOLTAGE
POWER SUPPLY J502-1 (+) and GND (-)?
Y N
Check the other +24 VDC outputs from the LOW
VOLTAGE POWER SUPPLY by referring to BSD
(CH1.5).
Is +24 VDC measured?
Y N
Check the +24V LVPS ENABLE signal to the
LOW VOLTAGE POWER SUPPLY.
Is +5 VDC measured?
Y N
Check the wire between the I/F PWB J534-
B4 and the LVPS J505-3. If no problems
are found, replace the MCU PWB.
(PL13.1)
Disconnect all the output connectors of the LOW
VOLTAGE POWER SUPPLY and check the
+24 VDC output.
Is +24 VDC measured?
Y N
Replace the LVPS1. (PL9.1)
A short circuit has occurred in the LVPS output
system circuit.
Repair the short circuit of the circuit by referring
to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1)
(WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3)
(WN4.3.16 +24 VDC-4)
Is the output from the LVPS normal?
Replace the MCU PWB. (PL13.1)
Repair the switch using the Generic Switch Failure FIP.
(PL2.10)
Check the installation status of the Actuator Cover.

001-301 L/H LOWER COVER INTERLOCK OPEN

Description The L/H LOWER COVER is open.
BSD on : CH8.2 CH8.6
Procedure
Run the DC330 [001-302].
Open the L/H LOW COVER, and turn the L/H LOWER
COVER INTERLOCK SENSOR On/Off with paper.
Is the display switched between H and L?
Y N
Use the Generic Permeable Sensor Failure FIP to repair the
L/H LOWER COVER INTERLOCK SENSOR. (PL2.3)
Check the installation status of the Actuator and the COVER. If
no problems are found, replace the MCU PWB. (PL13.1)
Chapter 3 Troubleshooting

001-302 FRONT COVER INTERLOCK OPEN

Description The FRONT COVER is open.
BSD on : CH1.7 CH1.9
Procedure
Remove the FRONT COVER. Cheat the FRONT COVER
INTERLOCK SWITCH.
Has the display of 001-302 been cleared?
Y N
Is +24 VDC measured between the I/F PWB J531-1 (+)
and GND (-)?
Y N
Is +24 VDC measured between the FRONT COVER
INTERLOCK SW J171-B1 (+) and GND (-)?
Y N
Is +24 VDC measured between the FRONT
COVER INTERLOCK SW J171-A1 (+) and
GND (-)?
Y N
Check the +24 VDC circuit to the L/H
COVER INTERLOCK SW J172-A1 by
referring to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1)
(WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3)
(WN4.3.16 +24 VDC-4)
Replace the FRONT COVER INTERLOCK
SWITCH. (PL10.1)
Check the wire between the FRONT COVER
INTERLOCK SWITCH J127-B1 and the I/F PWB
J531-1 for an open circuit or poor contact.
Check the wire between the I/F PWB and the MCU PWB.
If no problems are found, replace the MCU PWB.
(PL13.1)
If the problem persists, replace the I/F PWB. (PL9.1)
Check the installation status of the Actuator and the SWITCH.
