Overhaul; Recovery Of Li-Ion Hv Battery Assembly - Toyota Prius Manual

E mergency Response (2012 Model - Continued)

Overhaul

During overhaul, immobilize and disable the vehicle if not already done.
Refer to illustrations starting on page 61, 62 and 63. The HV battery
assembly cover should never be breached or removed under any
circumstances including fire. Doing so may result in severe electrical burns,
shock, or electrocution.
•
Immobilize Vehicle
Chock wheels and set the parking brake.
Push the P position switch to engage park (P).
•
Disable Vehicle
Perform these steps first if the charge cable assembly is
connected to the vehicle.
1. Disconnect the charge cable assembly connector from the
vehicle. To disconnect it, push the lock release button on the top
of the connector and pull it away from the vehicle.
2. Close the recharge inlet cap and charge inlet door.
3. Disconnect the plug of the charge cable assembly from the
electrical outlet.
Performing either of the following two procedures will shut the
vehicle off and disable the HV, SRS, charging and remote air
conditioning systems.
Procedure #1
1. Confirm the status of the READY indicator in the instrument
cluster. If the READY indicator is illuminated, the vehicle is on
and operational.
2. Shut off the vehicle by pushing the power button once.
3.
The vehicle is already shut off if the instrument cluster lights are
not illuminated. Do not push the power button because the
vehicle may start.
4. If the smart key is easily accessible, keep it at least 16 feet (5
meters) away from the vehicle.
5. Disconnect the 12 Volt auxiliary battery under the deck board
and auxiliary box in the cargo area to prevent accidental
restarting of the vehicle.
Procedure #2
1. Open the hood and remove the fuse box cover.
2. Remove the IG2 fuse (20A yellow colored) in the engine
compartment fuse box as illustrated on page 62. If the correct
fuse cannot be recognized, pull all fuses in the fuse box.
3. Disconnect the 12 Volt auxiliary battery under the deck board
and auxiliary box in the cargo area to prevent accidental
restarting of the vehicle.
NOTE:
Before disconnecting the 12 Volt auxiliary battery, if necessary, lower
the windows, unlock the doors, optional power seat and open the hatch
as required. Once the 12 Volt auxiliary battery is disconnected, power
controls will not operate.
WARNING:
•
The high voltage system, including the charging system, may remain
powered for up to 10 minutes after the vehicle is shut off, disabled, or
charging stops. To prevent serious injury or death from severe burns
or electric shock, avoid touching, cutting, or breaching any orange
high voltage power cable or high voltage component.
•
The SRS may remain powered for up to 90 seconds after the vehicle is
shut off or disabled. To prevent serious injury or death from
unintentional SRS deployment, avoid breaching the SRS components.
•
If none of the disabling procedures can be performed, proceed with
caution as there is no assurance that the high voltage electrical system,
SRS, fuel pump, recharging, or remote air conditioning are disabled.
