Determination Procedure<\/p>\n

\n
\n
Caution<\/div>\n<\/dd>\n
\n
\n
\u2022 When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.<\/div>\n
\u2022 When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.<\/div>\n
\u2022 Disconnect the negative battery cable before performing any work that requires handling of connectors.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n
