Inspecting the
continuity of
PCU wire har-
ness (lower
side)
1. Set the starter key to the
"LOCK" position.
2. Disconnect the HV ECU2 con-
nector.
3. Using the electrical tester, mea-
sure the resistance between
the lower-side connector termi-
nal of PCU harness (16P) and
the HV ECU2 connector termi-
nal.

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 11th
terminal of PCU harness (16P)
and the ground.

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).

Inspecting the
signal line of
PCU wire har-
ness (lower
side) for short
circuit
1. For the 11th terminal of PCU
harness (16P) lower-side con-
nector, inspect the signal line of
PCU wire harness (lower side)
for short circuit. (See "Inspect-
ing the PCU harness signal line
for short circuit.")
