Determination Procedure
-
Caution
-
• When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.• When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.• Disconnect the negative battery cable before performing any work that requires handling of connectors.
