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 DLC-2, touch it with a paper clip or similar thin pin without directly inserting a tester into the terminals.
•  Disconnect the negative battery cable before performing any work that requires handling of connectors.
Note
•  If the ignition does not turn on even if the ignition is switched ON, switch the ignition ON referring to the forced ignition ON procedure. (See FORCED IGNITION ON.)
