DESCRIPTION AND OPERATION

Electric Motor Management

Electric motor management is accomplished by the
traction inverter module (TIM). The TIM is located
in the rear of the vehicle under the bed of the truck.
The TIM converts high-voltage direct current from
the traction battery into high-voltage,  three-phase
alternating current to power the motor/transaxle.
Output from the TIM to the motor/transaxle is based
upon driver, sensor, and other module inputs.
