Circuit/System Description

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

This DTC indicates the transmission control module (TCM) has set an emission related transmission DTC. The engine control module (ECM) receives the TCM information over the serial data circuit. The ECM illuminates the malfunction indicator lamp (MIL) when the TCM sends a message over the serial data circuit requesting MIL illumination. The DTC information for the ECM will only display DTC P0700, but the freeze frame/failure records data may display the transmission DTC that set.
