DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
Each drive motor is controlled by a motor control module. The drive motor utilize 3 phase AC electricity. The drive motor stator coil is comprised of three phase circuits. The phase circuits are identified as phase U, phase V, and phase W. The U-V-W phase circuits are connected in a wye configuration. This means each phase is connected at a single, central point. The motor control modules monitor a current sensor connected to each drive motor generator phase. The current sensor is part of the drive motor assembly and is not serviced separately. The motor control module is part of the drive motor generator power inverter module and is not serviced separately.
