Avertissement

Seuls les techniciens qui ont été sensibilisés aux dangers de la haute tension et qui ont complété toutes les formations de certification requises (le cas échéant) sont autorisés à effectuer cette procédure. Portez toujours un équipement de protection personnelle et des gants isolants haute tension ayant un classement minimal de 0 (1000 volts) avant de manipuler un câble, une barre omnibus ou des raccords haute tension. Se référer à Tech Note TN-15-92-003, Mises en garde relatives à la haute tension pour des informations supplémentaires sur la sécurité.

Make sure that the insulation multimeter and leads are capable of handling at least 500V DC.

Procédure

  1. Remove the ancillary bay cover. See Couvercle - baie auxiliaire (retirer et remplacer).
  2. Set the insulation multimeter to measure resistance, and touch the probe tips together.

    CAUTION
    If the multimeter displays greater than 0.2 ohms, the leads are defective and must be replaced. Do not use defective leads.
  3. Consider your next step:
    • If the positive contactor is suspect to have seized, go to step 4.
    • If the negative contactor is suspect to have seized, go to step 9.
    • If both contactors are suspect, or there is uncertainty, start with step 4.
  4. Inspect the center of the insulator caps on top of the HV battery positive contactor terminals:
    • If the insulator caps have a probing hole, continue to step 5.
    • If the insulator caps are solid, remove the insulator caps and continue to step 5.
  5. Set the multimeter to measure the DC voltage across both terminals of the HV battery positive contactor, either through the probing hole of the insulator caps or directly onto the terminals:
    • If the measured voltage is outside the range of -0.1V to 0.1V, then the HV battery positive contactor is not seized. Continue to step 6.
    • If the measured voltage is between -0.1V and 0.1V, set the multimeter to measure resistance and measure the resistance across the HV battery positive contactor terminals:
      • If the measured resistance is greater than 1M Ohm (1000K Ohm), then the HV battery positive contactor is not seized. Proceed to step 6.
      • If the measured resistance is lower than 1M Ohm, then the HV battery positive contactor might be seized. Discontinue this procedure and replace the HV battery positive contactor, and then retest.
  6. Set the multimeter to measure resistance, and then perform the following measurements:

    Resistance Test

    Battery Positive

    (Rear terminal of HV battery positive contactor)

    B+

    (LH probe opening)

    GND

    Measured Resistance More Than 1 M Ohm

    Measured Resistance Less Than 1 M Ohm

    Battery positive to chassis

    Positive (+) lead

    Negative (-) lead

    Pass

    Fail

    Resistance is lower than expected in the battery pack itself. Escalate a Toolbox session.

    B+ to chassis

    Positive (+) lead

    Negative (-) lead

    Pass

    Fail

    Resistance is lower than expected in the HV battery positive contactor or ancillary bay. Replace the HV battery positive contactor, and then retest.
  7. Reinstall the HV battery positive contactor insulator caps, if they were removed earlier.
  8. If the HV battery negative contactor is also suspect to have seized, or there is uncertainty, go to step 9. Otherwise, return to the vehicle HV disablement procedure. See one of the following:
  9. Inspect the center of the insulator caps on top of the HV battery negative contactor terminals:
    • If the insulator caps have a probing hole at the center, continue to step 10.
    • If the insulator caps are solid, remove the insulator caps and continue to step 10.
  10. Set the multimeter to measure the DC voltage across both terminals of the HV battery negative contactor, either through the probing hole of the insulator caps or directly onto the terminals:
    • If the measured voltage is outside the range of -0.1V to 0.1V, then the HV battery negative contactor is not seized. Continue to step 11.
    • If the measured voltage is between -0.1V and 0.1V, set the multimeter to measure resistance and measure the resistance across the HV battery negative contactor terminals:
      • If the measured resistance is greater than 1M Ohm (1000K Ohm), then the HV battery negative contactor is not seized. Proceed to step 11.
      • If the measured resistance is lower than 1M Ohm, then the HV battery negative contactor might be seized. Discontinue this procedure and replace the HV battery negative contactor, and then retest.
  11. Set the multimeter to measure resistance, and then perform the following measurements:

    Resistance Test

    Battery Negative

    (LH terminal of HV battery negative contactor)

    B-

    (RH probe opening)

    GND

    Measured Resistance More Than 1 M Ohm

    Measured Resistance Less Than 1 M Ohm

    Battery negative to chassis

    Positive (+) lead

    Negative (-) lead

    Pass

    Fail

    Resistance is lower than expected in the battery pack itself. Escalate a Toolbox session.

    B- to chassis

    Positive (+) lead

    Negative (-) lead

    Pass

    Fail

    Resistance is lower than expected in the HV battery negative contactor or ancillary bay. Replace the HV battery negative contactor, and then retest.
  12. Reinstall the HV battery negative contactor insulator caps, if they were removed earlier.
  13. Return to the vehicle HV disablement procedure. See one of the following:
