1. A control system for performing an expedited start-up procedure of an electrified vehicle, the control system comprising:
a hybrid control processor (HCP) connected to a controller area network (CAN) having a plurality of electrified powertrain (ePT) ECUs/modules; and
an auxiliary hybrid control processor (AHCP) connected to the CAN and connected to the HCP via a hardwire wakeup line;
wherein in response to a start-up request for the electrified vehicle, the HCP is configured to initialize a start-up procedure in which the HCP:
sends a wakeup signal to the AHCP via the hardwire wakeup line,
performs shutoff path testing via a first CAN bus, and
confirms communication with the plurality of ePT ECUs/modules via a second CAN bus to complete the start-up procedure; and
wherein in response to the wakeup signal from the HCP, the AHCP is configured to initialize and then participate in the start-up procedure in which the AHCP wakes up and enables communication by the plurality of ePT ECUs/modules via the second CAN bus, and
wherein a duration of the start-up procedure is less than a predetermined customer annoyance threshold.
