Circuit/System Testing

    NOTE:

    You must perform the Component Testing before proceeding with Circuit/System Testing.

  1. Verify that DTC P0A3F, P0A40, P0C52, P0C53, P0C5C, P0C5D, or P1B03 are not set.
  2. Vehicle OFF, disconnect the X175 harness connector at the transmission.
  3. Install the DT-44152  jumper harness to the harness side only.
  4. Disconnect the X1 harness connector at the T6 power inverter module.
  5. Test for less than 1 Ω between the terminals listed below:
    • DT 44152 Terminal L and X1 terminal 1
    • DT 44152 Terminal M and X1 terminal 12
    • DT 44152 Terminal U and X1 terminal 2
    • DT 44152 Terminal T and X1 terminal 13
    • DT 44152 Terminal W and X1 terminal 3
    • DT 44152 Terminal V and X1 terminal 14
    • If greater that the specified range, test the signal circuit for an open/high resistance.
  6. If all circuits test normal, replace the drive motor generator position sensor.
