1. A dual controller area network (CAN) system for starting a vehicle, comprising:
- a transmission control unit (TCU);
an engine control unit (ECU); and
a dual CAN bus network comprising a first CAN (CAN1) bus and a second CAN (CAN2) bus,wherein the TCU is in communication with the ECU via the dual CAN bus network,wherein the ECU controls actuation of a starter motor in a first mode or a second mode based on one or more signals from the CAN1 bus and one or more signals from the CAN2 bus sent by the TCU, andwherein actuation of the starter motor places an engine of the vehicle in a starting mode.

Abstract
According to one or more aspects, a dual controller area network (CAN) is used to start a vehicle. A dual CAN bus network includes a first CAN (CAN1) bus and a second CAN (CAN2) bus. A transmission control unit (TCU) is in communication with an engine control unit (ECU) via the dual CAN bus network. The ECU controls actuation of a starter motor based on signals from the CAN1 bus and signals from the CAN2 bus sent by the TCU. Actuation of the starter motor places an engine of the vehicle in a starting mode.
