DTC Description: Notes

WARNING: This page is about a different car, the 2016 Infiniti Q50. However, it is still accessible from the selected car via links, so may be relevant.

The ECM receives two vehicle speed signals via the CAN communication line. One is sent from "combination meter", and the other is from TCM (Transmission control module). The ECM uses these signals for ASCD control. Refer to SYSTEM DESCRIPTION for ASCD functions.
