Inspecting the
voltage of
PCU wire har-
ness (upper
side)
1. Set the starter key to the
"LOCK" position.
2. Connect all the connectors that
have been disconnected.
3. Disconnect the connector of
HV battery cooling fan.
4. Set the starter key to the "ON"
position.
5. Using the electrical tester, mea-

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.

Inspecting the
signal line of
PCU wire har-
ness (upper
side) for short
circuit
1. Set the starter key to the
"LOCK" position.
2. Disconnect the PCU harness
(16P) connector.
3. For the 11th terminal of PCU
upper-side wire harness con-
nector, inspect the signal line of
PCU wire harness (upper side)
for short circuit. (See "Inspect-
ing the PCU harness signal line
for short circuit.")
