Inspection Procedure

WARNING:
  • Wear electrically insulated gloves and pull out the service plug grip before inspection as procedures may require disconnecting high-voltage connectors. Be sure to carry the removed service plug grip to prevent other technicians from accidently reinstalling it.
  • Do not touch the high-voltage connectors or terminals for 10 minutes after the service plug grip is removed.
  • After removing the service plug grip, turning the ignition switch ON (READY) may cause a malfunction. Do not turn the ignition switch ON (READY) unless instructed by the repair manual.
