REMOVAL AND INSTALLATION
 
 
caution
  • If the main drive lithium-ion battery is replaced, the "preliminary application" is required before replacement. (For the details, contact Mitsubishi Motors dealer.) If the main drive lithium-ion battery is replaced without approval by the "preliminary application", it is excluded from the scope of the warranty. Be careful.
  • If the main drive lithium-ion battery is replaced, use the scan tool (M.U.T.-IIISE) to initialize the main drive lithium-ion battery capacity estimation information and control information [Refer to GROUP 00 - Precautions before Service, Initialize Estimated Information and Control Information of Main Drive Lithium-ion Battery Capacity (Battery Maintenance Function) ].
danger
  • When servicing the high-voltage system parts, be sure to wear the specified protection equipment and disconnect the service plug to interrupt the high-voltage supply (Refer to ).
  • Do not disassemble any main drive lithium-ion battery other than those described in this manual.
Pre-removal Operation
  • Refrigerant Discharge (Refer to GROUP 55 - On-vehicle Service .)
  • Engine Compartment Undercover Front A and B Removal (Refer to GROUP 51 - Under Cover .)
Post-installation Operation
  • Refrigerant Refilling (Refer to GROUP 55 - On-vehicle Service .)
  • Engine Compartment Undercover Front A and B Installation (Refer to GROUP 51 - Under Cover .)

<<E>> MAIN DRIVE LITHIUM-ION BATTERY ASSEMBLY REMOVAL
1. Attach the removed work hole lid and O-ring to the main drive lithium-ion battery so that no water, foreign material, etc. enter the inside of the main drive lithium-ion battery.
2. Use the following special tools and 2 wood blocks [RH: 90 (3.54) x 90 (3.54) x 1500 (59.1) mm (inches), LH: 90 (3.54) x 90 (3.54) x 1650 mm (65.0) mm (inches).]
(1) Remove the handle of the special tool MB992336 and set the wood blocks.
(2) When the vehicle is lowered with the lift using the above special tool MB992336, if the lower stopper lock does not work, use the special tool MB992659 instead.
noteFor how to use the EV battery lifting cart in detail, refer to the provided "Operation Manual".
3. With the main drive lithium-ion battery installed on the vehicle, remove the mounting bolts (2 at front and 2 at rear of the main drive lithium-ion battery).
4. Loosen the remaining mounting bolts (4 locations).
5. Lower the vehicle with the lift until just before the bottom of the main drive lithium-ion battery contacts the wood block.
6. Remove all the mounting bolts on the main drive lithium-ion battery.
7.
caution
  • Be careful of damage due to wiring harness caught or hooked.
  • Make sure that the weld bolt at the battery tray does not interfere with wood blocks.
Raise the vehicle with the lift and remove the main drive lithium-ion battery.
8.
danger
  • Store the main drive lithium-ion battery on a place with no risk of wetting.
  • Do not bring the main drive lithium-ion battery close to fire or heat it to 60°C (140°F) or more.
Cover around the service plug of the main drive lithium-ion battery with a vinyl sheet or others so that no water, foreign material, etc. enter the inside of the main drive lithium-ion battery.
9. When moving the removed main drive lithium-ion battery with a crane or others, use the special tool MB992343 to sling it up in accordance with the following procedure.
  • Special tool MB992343
    • MB992344 x 4
