Automatic Transmission Overhaul: Application
WARNING:
The Prius charging system uses about 300 volts. Do not attempt to service system, as it requires special tools and training.
WARNING:
When performing any inspection or service procedure on this vehicle, ensure the following service precautions are followed to prevent personal injury or death due to the extremely high voltage:
- Ensure ignition is off and ignition key is removed from ignition before performing any inspection or service procedure in engine compartment, as engine may automatically start and shut off when ignition is on.
- Read all service and warning labels in engine compartment before performing any procedures in engine compartment.
- All high voltage wire harness connectors contain Orange connectors. DO NOT touch any wiring harness that contains Orange connectors.
- High voltage battery and other high voltage components may be identified by HIGH VOLTAGE caution labels. DO NOT touch these components.
- If necessary to inspect or service high voltage system, ensure ignition is off. Remove service plug to prevent electrocution. Service plug is located at left side trim panel in trunk. Carry service plug in your pocket to prevent other technicians from reinstalling it while vehicle is being serviced. After removing the service plug, wait at least 5 minutes to allow condenser inside the inverter to discharge before touching any high voltage wiring harness, connectors or components.
- If necessary to touch any high voltage wiring harness, connectors or components, use insulated gloves. Ensure insulated gloves are dry and in good condition and that no holes exist in insulated gloves by applying air pressure to insulated glove before touching any high voltage wiring harness, connectors or components.
- DO NOT wear any metal objects while working on vehicle which may accidently drop and cause a short circuit.
- If any high voltage wiring harness connector is disconnected, ensure terminal on wiring harness connector is wrapped with tape to prevent wiring harness connector from contacting any surface.
- If servicing high voltage system, place sign on roof of vehicle to indicate to other technicians that high voltage system is being serviced.
NOTE:
Only overhaul information for transaxle is provided in this article. Electric motor diagnosis and repair should be accomplished by a certified Toyota technician, due to possible personal injury from high voltage.
