DRIVE UNITS

The rear drive unit is located between the rear wheels, and the front drive unit (if equipped) is located between the front wheels. The
drive units convert the direct current (DC) from the high voltage battery into 3-phase alternating current (AC) that the drive units use

to power the wheels.

NOTE: The following image shows a Dual Motor vehicle. Vehicles without a front drive unit are similar. The motors depicted in this

image may not exactly match the vehicle you are working on.
