Component Description
WARNING: This page is about a different car, the 2005 Infiniti FX45. However, it is still accessible from the selected car via links, so may be relevant.
The ECM receives two vehicle speed sensor signals via CAN communication line. One is sent from "unified meter and A/C amp.", and the other is from TCM (Transmission control module). The ECM uses these signals for ASD control. Refer to "AUTOMATIC SPEED CONTROL DEVICE (ASD) " for ASD functions.
