Check Electrical Resistance Between E-Motor Phases

WARNING: This page is about a different variant/trim than selected.
WARNING:

On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury.

Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE to perform the High Voltage Power Down procedure.

  1. Disconnect 3-phase Wiring Harness from the e-Motor.
  2. Use a qualified micro Ohm measurement instrument to measure the resistance value between the three pins (U/V/W) of the e-Motor, 3 measurements in total (U-V, U-W, V-W).
  3. If measured resistance value is not between 27.36mOhms and 30.24mOhms, replace e-Motor in accordance with the service information.
