Inspecting the
vehicle wire
harness for
short circuit
1. Disconnect the PCU harness
(12P) connector.
2. Using the electrical tester, mea-
sure the resistance between
the terminals of PCU harness
(12P) vehicle-side connector
and the ground.

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
