Checking the
number of rev-
olutions of HV
battery cool-
ing fan [HINO-
DX]
1. In [Activation Test] on the diag-
nosis tool screen, change the
operation duty value of HV bat-
tery cooling fan to 20 and 90%.
2. In the [Data Monitor] on the
diagnosis tool screen, select
[Number of revolutions of HV
battery cooling fan] and read
the number of revolutions at
each duty value.
<Measurement conditions>
Starter key: ON
<Measured item>
Number of revolutions of HV bat-
tery cooling fan
<Standard values>
Duty value (20%) : 1416 r/min or
lower
Duty value (90%) : 3742 r/min or
lower
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
HV battery
cooling fan.

Inspecting the
continuity of
PCU wire har-
ness (lower
side)
1. Set the starter key to the
"LOCK" position.
2. Disconnect the connectors of
HV ECU1 and PCU harness
(16P).
3. Using the electrical tester, mea-
sure the resistance between
the HV ECU1 connector and
the lower-side connector termi-
nal of PCU harness (16P).
<Measurement conditions>
Starter key: LOCK
<Tester connections>
HV ECU1 connector
–
PCU har-
ness (16P) lower-side connector
24th terminal
–
12th terminal
<Standard values>
Less than 1
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 6.
Replace the
PCU wire har-
ness (lower
side).

Inspecting the
PCU wire har-
ness (lower
side) for short
circuit
1. Using the electrical tester, mea-
sure the resistance between
the lower-side connector 12th
terminal of PCU harness (16P)
and the ground.
<Measurement conditions>
Starter key: LOCK
<Tester connections>
PCU harness (16P) lower-side
connector

<Standard values>
10 k
or more
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 7.
Replace the
PCU wire har-
ness (lower
side).
