ATTENTION
To ensure proper torque when replacing an old charger with a new charger, replace all patch bolts with new bolts. However, when reinstalling an old charger, reuse the original patch bolts to avoid an excess buildup of thread locker patch material. Excess patch material requires increased torque to fasten and may result in loose connections.
Informational PurposesAn informational icon, calling your attention
Remarque
In three-phase markets, 4 cables connect the charger to the charge port instead of 2.

Warning
The HV harness bracket must be reinstalled on the rear of the charger to ensure proper performance in the event of a collision.
  • Clean the charger mounting area on the vehicle before installing the new charger.
  • Ensure that the new charger has a new foam gasket on the bottom of the charger. Do not reuse the foam gasket.
  • The forward HV cables must be inserted into the charger before it is permanently mounted. Place the charger in the approximate mounting position, tilted toward the center of the vehicle, then connect the forward HV cables.
  • The lugs of the forward HV cables must be positioned in front of the busbars.
  • Informational PurposesAn informational icon, calling your attention
    Note
    The charger is difficult to position properly. Position the charger in the approximate position, then check under the vehicle to see the position of the coolant nipple, electrical connector, and studs relative to the holes in the body. Adjust the position of the charger accordingly.
  • After reinstalling the HV Battery cables, confirm that there is no cross-threading:
    • Visually inspect the nuts for cross-threading; a cross-threaded nut will not be seated deeply.
    • Visually inspect for cable movement near the stud by pushing and pulling on the cable.
  • After reinstalling the charge port cables, confirm that there is no cross-threading:
    • Visually inspect for cable movement near the stud by pushing and pulling on the cable.
    • Visually inspect the nuts for cross-threading; a cross-threaded nut will not be seated deeply.
    • Single Phase only: Use the Hioki Impedance Tester to measure the impedance between the spade connector and the adjacent busbar. The acceptable impedance is between 0.010 mΩ (10 μΩ) and 0.100 mΩ (100 μΩ). If the impedance is outside those bounds, reposition the probes and measure again. If the impedance is repeatedly between 0.00 mΩ and 0.010 mΩ (10 μΩ), the Hioki test passed, proceed with the installation procedure.For more information on Hioki impedance testing, refer to Toolbox article 218200.
  • Clean the adhesive residue on the charger and charger access panel with an alcohol wipe. Let the alcohol dry before installing a new warranty label.
  • Make sure that the forward HV cable grommet is fully seated on the body.
  • Tip : If the forward HV cable grommet is difficult to insert into the body, apply P-80 emulsion to the edges of the grommet.
  • Update the vehicle firmware. See Mise à jour du micrologiciel.
    Tip : Connect 12V power and start the firmware update before reinstalling the components that were removed for access.

  • Refill and bleed the cooling system. See Circuit de refroidissement - remplissage partiel et purge.

  • Make sure that the vehicle charges as expected.
