Inspecting the
PCU wire har-
ness (lower
side) for conti-
nuity 1
1. Set the starter key to the
"LOCK" position.
2. Disconnect the connectors of
inverter and PCU harness
(16P).
3. Using the electrical tester, mea-
sure the resistance between
the terminals of inverter con-
nector and PCU harness (16P)
lower-side connector.

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 2.
Replace the
PCU wire har-
ness (lower
side).

nuity 2
1. Using the electrical tester, mea-
sure the resistance between
the 15th terminal of PCU har-
ness (16P) lower-side connec-
tor and the ground.
<Measurement conditions>
Starter key: LOCK

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 3.
Replace the
PCU wire har-
ness (lower
side).

Inspecting the
wire harness
in the HV bat-
tery for conti-
nuity
1. Remove the PCU top cover.
2. Disconnect the SMR drive con-
nector from the high-voltage J/
B (in the battery pack).
3. Using the electrical tester, mea-
sure the resistance between
the terminals of PCU harness
(16P) upper-side connector
and SMR drive connector.
<Measurement conditions>
Starter key: LOCK
<Tester connections>
PCU harness (16P) upper-side
connector
–
SMR drive connector
2nd terminal
–
3rd terminal
15th terminal
–
2nd 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 4.
Replace the
main wire har-
ness in the HV
battery.
After replace-
ment, go to
step 4.
