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 terminal before performing any work that requires handling of connectors.
