Checks
Turn ON the main power supply
switch. Is the error code indi-
cated?
Is AC power present?
Turn OFF the main power
switch, and disconnect all fol-
lowing connectors:
Composite Power Supply PCB
J204, J211, J213, J214, J215
ACC Power Supply
J134, J142
Is the output voltage of each
terminal (Table 7-00) normal?
Is the fuse blown?
Yes/No

NO
Action
See the descriptions for the
error code indicated.
See “AC power is absent.”
Turn OFF the power switch,
connect one of the disconnect-
ed connectors, and turn ON
the power switch. Repeat this
for all connectors to find the
connector that activates the
protection circuit. Then, check
the wiring from that connector
and DC loads.
Replace the fuse.
Check the DC loads of the
fuse in question and wiring.
Replace the composite power
supply PCB or the ACC power
supply PCB.
