Inspecting the
vehicle wire
harness for
short circuit
1. Using the electrical tester, mea-
sure the resistance between
the terminals of PCU harness
(12P) vehicle-side connector
and the ground.
2. Using the electrical tester, mea-
sure the resistance between
the terminals of PCU harness
(12P) vehicle-side connector.
<Measurement conditions>
Starter key: LOCK
