Overhaul; Recovery/Recycling Nimh Hv Battery Pack - Toyota Highlander 2006 Manual

Emergency Response (Continued)
Fire (Continued)
When allowed to burn themselves out, the Highlander hybrid NiMH
battery modules burn rapidly and can quickly be reduced to ashes
except for the metal.
Offensive Fire Attack
Normally flooding the NiMH HV battery pack with copious amounts
of water at a safe distance will effectively control the HV battery pack
fire by cooling the adjacent NiMH battery modules to a point below
their ignition temperature. The remaining modules on fire, if not
extinguished by the water, will burn themselves out.
However, flooding the Highlander hybrid HV battery pack is not
recommended due to battery design and forward location preventing
the responder from properly applying water through the available vent
openings safely. It is recommended that the incident commander
allow the Highlander hybrid HV battery pack to burn itself out.
Defensive Fire Attack
If the decision has been made to fight the fire using a defensive
attack, the fire attack crew should pull back a safe distance and allow
the NiMH battery modules to burn themselves out. During this
defensive operation, fire crews may utilize a water stream or fog
pattern to protect exposures or to control the path of smoke.

Overhaul

During overhaul, immobilize and disable the vehicle if not already
done. See illustrations on page 15.
• Immobilize Vehicle
Chock wheels and set the parking brake.
Move the shift lever to the P (Park) position.
• Disable Vehicle
Performing either of the following two procedures will shut the
vehicle off and disable the HV battery pack, SRS, and gasoline fuel
pump.
Procedure #1
1. Turn the ignition key off.
2. Remove the key and place on dash. If the key cannot be removed,
disconnect the 12-Volt auxiliary battery in the engine
compartment.
Procedure #2 (Alternate if ignition key is inaccessible).
1. Disconnect the 12-Volt auxiliary battery in the engine
compartment.
2. Remove the fuse box cover.
3. Remove the IGCT No. 4 fuse (10A Red colored) in the engine
compartment junction block. When in doubt, pull all four fuses
in the fuse block.
WARNING:
•
High voltage electricity can cause death or serious injury from
severe burns or electric shock. To avoid death or serious
injury wait 5 minutes after disabling the vehicle to discharge
high voltage electricity, and do not touch, cut, or open any
orange high voltage power cable or high voltage component.
•
The SRS airbags can cause death or serious injury by sudden
deployment. To avoid death or serious injury wait 90 seconds
after disabling the vehicle to allow the SRS backup power to
discharge.
•
If neither of the disabling procedures can be performed,
proceed with caution as there is no assurance that the high
voltage electrical system, SRS, or fuel pump are disabled.
