Circuit Description
WARNING: This page is about a different car, the 2002 Infiniti QX4, 2001 Nissan Pathfinder, and 2001 Infiniti QX4. However, it is still accessible from the selected car via links, so may be relevant.
The ECM and TCM provide mutual communication in relation to engine output control signal (ignition timing retard signal) during rapid standing starts/acceleration. With this consistent real-time control, the shifting feel is substantially improved.
