Inspecting the
PCU wire har-
ness (lower
side) for conti-
nuity 2
1. Using the electrical tester, mea-
sure the resistance between
the terminals of inverter con-
nector and PCU harness (24P)
lower-side connector.
<Measurement conditions>
Starter key: LOCK
<Tester connections>
Inverter connector to PCU har-
ness (24P) lower-side connector
10th terminal –16th terminal
11th terminal – 16th terminal
<Standard values>
1
or less (With continuity)
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
PCU wire har-
ness (lower
side).

Inspecting the
inverter cool-
ing pump and
inverter cool-
ing radiator fan
for short circuit
1. Using the electrical tester, mea-
sure the resistance between
the terminals of inverter cooling
pump connector and PCU har-
ness (24P) lower-side connec-
tor.
2. Using the electrical tester, mea-
sure the resistance between
the terminals of inverter cooling
radiator fan connector and PCU
harness (24P) lower-side con-
nector.
<Measurement conditions>
Starter key: LOCK
<Tester connections>
Inverter cooling pump connector
– PCU harness (24P) lower-side
connector
4th connector – 16th connector
Inverter cooling radiator fan con-
nector – PCU harness (24P)
lower-side connector
1st terminal – 16th terminal
<Standard values>
10 k
or more (No continuity)
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
inverter cool-
ing pump or
inverter cool-
ing radiator
fan.

Inspecting the
PCU wire har-
ness (lower
side) for short
circuit 2
1. Remove the inverter start relay.
2. Using the electrical tester, mea-
sure the resistance between
the 1st terminal of inverter start
relay connector (relay block
side) and the ground.
<Measurement conditions>
Starter key: LOCK
<Tester connections>
Inverter start relay connector
(relay block side)
1st terminal – GND
<Standard values>
10 k
or more (No continuity)
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).
