caution
  • If the traction battery is replaced, the "preliminary application" is required before replacement. (For the details, contact Mitsubishi Motors dealer.) If the traction battery is replaced without approval by the "preliminary application", it is excluded from the scope of the warranty. Be careful.
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 GROUP 00 - Precautions before service, Precautions on how to use the high-voltage vehicle ).
  • Do not disassemble any traction battery other than those described in this manual.
Pre-removal operation
  • Front floor cover A, B removal (Refer to GROUP 51 - Under Cover )
  • Front floor console heater duct removal (Refer to GROUP 55 - Duct )

Post-installation operation
  • Front floor console heater duct installation (Refer to GROUP 55 - Duct )
  • Front floor cover A, B installation (Refer to GROUP 51 - Under Cover )

REMOVAL SERVICE POINTS



<<A>> RUBBER BOOT DISCONNECTION





Disengage the hook of the rubber boot and push it out of the vehicle (towards under the vehicle).

<<B>> TRACTION BATTERY CABLE DISCONNECTION



1.Remove the inner cable mounting bolts (2 locations).
2.Remove the outer cable mounting bolts (2 locations).
3.Pull out the cable from the traction battery.

<<C>> QUICK CHARGING CABLE DISCONNECTION



1.Remove the inner cable mounting bolts (2 locations).
2.Remove the outer cable mounting bolts (2 locations).
3.Pull out the cable from the traction battery.

<<D>> TRACTION BATTERY ASSEMBLY REMOVAL


1.Attach the removed work hole lid and O-ring to the traction battery so that no water, foreign material, etc. enter the inside of the traction battery.


2.Use the following special tools and 2 wood blocks (100 x 100 x 1500 mm).
(1) Remove the handle of the EV battery cart (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 EV battery lifting cart (special tool: MB992659) instead.
note For how to use the EV battery lifting cart in detail, refer to the provided "Operation Manual".
3.With the traction battery installed on the vehicle, remove the mounting bolts (2 at front and 2 at rear of the traction battery).
4.Loosen the remaining mounting bolts (6 locations).

5.Lower the vehicle with the lift until just before the bottom of the traction battery contacts the wood block.
6.Remove all the mounting bolts on the traction battery.

7.
caution Be careful of damage due to wiring harness caught or hooked.
Raise the vehicle with the lift and remove the traction battery.


8.
danger
  • Store the traction battery on a place with no risk of wetting.
  • Do not bring the traction battery close to fire or heat it to 60°C or more.
Cover around the air outlet of the traction battery (computer unit portion) with a vinyl sheet or others so that no water, foreign material, etc. enter the inside of the traction battery.




9.When moving the removed traction battery with a crane or others, use the EV battery sling tool kit (special tool: MB992343) to sling it up in accordance with the following procedure.

  • EV battery sling tool kit (MB992343)

    • Eye bolts (MB992344 x 4)
    • EV battery sling belts (MB992345 x 2)
    • Washers (MF450156 x 8)
    • Hexagon nuts (MU001480 x 4)
note For how to use the EV battery sling belt in detail, refer to the provided "Operation Manual".
(1) Mark the centre of the EV battery sling belt (MB992345) and positions 275 mm right and left from the centre.
note The marking is intended for alignment of the EV battery sling belt and eye bolt.
(2) Install the eye bolts (MB992344), washers (MF450156) and nuts (MU001480) onto the positions (2 each at the right and left) on the traction battery as shown in the figure.
(3) Pass the EV battery sling belt through the eye bolts and align the marks on the EV battery sling belt to the eye bolt positions.
(4) Bind 2 EV battery sling belts together and sling up the traction battery with a crane or others.
