Page 11: Step 1: Assessing Damage To The Main Drive Lithium- Ion Battery
Step 1: Assessing Damage to the Main Drive Lithium-ion Battery Immediately after receiving the vehicle, and prior to any dismantling work, check for damage to the Main drive lithium-ion battery. If the Main drive lithium-ion battery is severely damaged, the Main drive lithium-ion battery must be discharged by soaking in water prior to any dismantling work in order to reduce the risk of electric shock and/or fire. -
Page 12: Step 2A: Shutting Off The High Voltage
Step 2A: Shutting Off the High Voltage WARNING; If the Main drive lithium-ion battery is severely damaged, do not carry out the procedures described in this section. Instead, discharge the Main drive lithium-ion battery in accordance with Step 2B. 1) Shut down the vehicle’s high voltage system using one of the following two methods. This will disconnect the high voltage electricity current supplied from the Main drive lithium-ion battery. - Page 13 2) Wait at least 1 minute before proceeding to the next step. High voltage system shut down is performed during this waiting time. 3) Disconnect the 12V battery negative terminal. This will disconnect the power supply to the SRS airbag system and the EV ECU. Disconnect the 12V battery negative terminal by using a 10mm wrench as follows: ①...
- Page 14 ② Pull up the lever of the Service Plug and then remove the Service Plug by pulling upward on the lever. WARNING; After removing the Service Plug, keep it in a secure place away from other dismantlers to prevent accidental handling/improper re-installation. ...
- Page 15 ② Remove the service hole lids on the bottom of the Main drive lithium-ion battery and carry out the measurement of the battery’s voltage as shown below. If the voltage is not 0V, wait until the voltage shows 0V. When the high voltage circuit is successfully shut down, the voltage shows 0V.

Page 16: Step 2B: Discharging The Main Drive Lithium-Ion Battery
Step 2B: Discharging the Main Drive Lithium-ion Battery WARNING; - Do not use salt water to discharge the Main drive lithium-ion battery. Using water containing salt can generate a large volume of flammable hydrogen and increases the risk of fire or explosion. - Hydrogen gas is generated during the discharging process, even when fresh water is used and proper discharging procedures are followed. - Page 17 2) Draining the Main drive lithium-ion battery Step 1. After 72 hours have elapsed, remove the vehicle from the water. Step 2. Remove the Under cover (2 pieces) from bottom of vehicle. (see illustration below.) - Use Socket wrench (size 10mm) for removing the fixing bolts. - Use Flat head screwdriver for removing of the fixing clips.
- Page 18 Drain hole locations on Main drive lithium-ion battery Service hole lid: Remove the service hole lids on the bottom of the Main drive lithium-ion battery and drain the Main drive lithium-ion battery. Main drive lithium-ion battery Front end of Main drive lithium-ion battery: Use a drill (diameter size 6mm or less) to drill drain holes in the five marked locations on the front bottom of the Main drive lithium-ion battery.
- Page 19 3) Disconnect 12V battery under the front hood. WARNING; Disconnect 12V battery to avoid inadvertent airbag deployment during the dismantling process, since the 12V battery may not have discharged while the vehicle was soaking for 72 hours in water. Since the 12V battery will not discharge while the vehicle is soaking in water; The hood release is under the instrument panel beside the front passenger’s door.
