INSPECTION PROCEDURE

CAUTION:
^ Before inspecting the high-voltage system, take safety precautions to prevent electrical shocks, such as wearing insulated gloves and removing the service plug grip. After removing the service plug grip, put it in your pocket to prevent other technicians from reconnecting it while you are working on the high-voltage system.
^ After disconnecting the service plug grip, wait for at least 5 minutes before touching any of the high-voltage connectors or terminals.
^ Wear insulated gloves, turn the ignition switch off, and disconnect the negative terminal of the auxiliary battery before touching any of the orange-colored wires of the high-voltage system.

NOTICE:
^ After removing the service plug grip, do not put the vehicle into the READY-on state, unless instructed by the repair manual.
^ Turn the ignition switch off before disconnecting or reconnecting any connector.
