During service of a 2-Mode hybrid drive motor, the motor harness can easily be damaged if the appropriate precautions are not used. When reinstalling a
drive motor, sharp edges of the transmission case access opening may chafe or cut the harness when the drive motor is fed through the case opening.
Recommendation
Use the procedure and parts below to protect the drive motor harness PRIOR to reinstallation into the transmission case.
1. Remove the black plastic wiring harness clip (1) from the motor casing and pull the harness out of the clip, exposing the drive motor wires (2).
