Inspecting the
high-voltage J/
B (in the bat-
tery pack)
1. Using the electrical tester, mea-
sure the resistance between
the terminals of high-voltage J/
B (in the battery pack). (with
SMR#2 removed).

The mea-
sured value is
within the
range of stan-
dard value: Go
to YES.
The mea-
sured value is
not within the
range of stan-
dard value: Go
to NO.
Go to step 5.
Replace the
high-voltage J/
B (in the bat-
tery pack).
After replace-
ment, go to

Restoration
check [HINO-
DX]
1. Connect all the connectors that
have been disconnected to
restore the system.
2. Set the starter key to the "ON"
position.
3. Clear the malfunction history.
4. Perform a test run. (accelerate
and decelerate running for
approximately 1 hour).
5. In [Fault Information] on the
diagnosis tool screen, check if
P0AA1-D8 is detected.
DTC P0AA1-
D8 is detected:
Go to YES.
DTC P0AA1-
D8 is not
detected: Go
to NO.
Replace the
inverter.
The inspec-
tion is com-
