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.
