DTC P1574: ASCD Vehicle Speed Sensor: Description

WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

The ECM receives 2 vehicle speed sensor signals via CAN communication line. One is sent from the combination meter, and the other is from the Transmission Control Module (TCM). The ECM uses these signals for ASCD control.
