Toyota Camry AVV50 Series, 2012 Camry hybrid 4-door sedan Dismantling Manual

Gasoline-Electric Hybrid Synergy Drive
AVV50 Series
Foreword
This guide was developed to educate and assist dismantlers in the safe handling of Toyota Camry gasoline-electric hybrid vehicles. Camry hybrid dismantling procedures are similar to other non-hybrid Toyota vehicles with the exception of the high voltage electrical system. It is important to recognize and understand the high voltage electrical system features and specifications of the Toyota Camry hybrid, as they may not be familiar to dismantlers. High voltage electricity powers the A/C compressor, electric motor, generator, and inverter/converter. All other conventional automotive electrical devices such as the headlights, radio, and gauges are powered from a separate 12 Volt auxiliary battery. Numerous safeguards have been designed into the Camry hybrid to help ensure the high voltage, approximately 244.8 Volt, Nickel Metal Hydride (NiMH) Hybrid Vehicle (HV) battery pack is kept safe and secure in an accident. The NiMH HV battery pack contains sealed batteries that are similar to rechargeable batteries used in some battery operated power tools and other consumer products. The electrolyte is absorbed in the cell plates and will not normally leak out even if the battery is cracked. In the unlikely event the electrolyte does leak, it can be easily neutralized with a dilute boric acid solution or vinegar. High voltage cables, identifiable by orange insulation and connectors, are isolated from the metal chassis of the vehicle.
Additional topics contained in the guide include:
Toyota Camry hybrid identification.
Major hybrid component locations and descriptions.
By following the information in this guide, dismantlers will be able to handle Camry hybrid-electric vehicles as safely as the dismantling of a conventional non-hybrid automobile.

About the Camry Hybrid
The Camry hybrid continues into its 2nd generation as a gasoline-electric hybrid vehicle. Hybrid Synergy Drive means that the vehicle contains a gasoline engine and electric motors for power. The two hybrid power sources are stored on board the vehicle:
1. Gasoline stored in the fuel tank for the gasoline engine.
2. Electricity stored in a high voltage Hybrid Vehicle (HV) battery pack for the electric motor.
The result of combining these two power sources is improved fuel economy and reduced emissions. The gasoline engine also powers an electric generator to recharge the battery pack; unlike a pure all electric vehicle, the Camry hybrid never needs to be recharged from an external electric power source.
Depending on the driving conditions one or both sources are used to power the vehicle. The following illustration demonstrates how the Camry hybrid operates in various driving modes.
n During light acceleration at low speeds, the vehicle is powered by the electric motor.
The gasoline engine is shut off.
o During normal driving, the vehicle is powered mainly by the gasoline engine. The
gasoline engine also powers the generator to recharge the battery pack.
p During full acceleration, such as climbing a hill, both the gasoline engine and the electric
motor power the vehicle.
q During deceleration, such as when braking, the vehicle regenerates the kinetic energy
from the wheels to produce electricity that recharges the battery pack.
r While the vehicle is stopped, the gasoline engine and electric motor are off, however the
vehicle remains on and operational.

Camry Hybrid Identification
In appearance, the 2012 model year Camry hybrid is a 4-door sedan. Exterior, interior, and engine compartment illustrations are provided to assist in identification.
The alphanumeric 17 character Vehicle Identification Number (VIN) is provided in the front windshield cowl, right side floor and on the left side B pillar.
Example VIN:
4T1BD1FK0CU001001 (U.S.A., Canada and South Korea) JTNBD4FK0CU001001 (General)
A Camry hybrid is identified by the first 8 alphanumeric characters 4T1BD1FK or JTNBD4FK.
