Circuit Description

WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The TCM monitors the microprocessor status. When there is a microprocessor reset, the controller software will run a power-up cycle. If there is a power-up cycle without having a power-down, then the controller will interpret this as a running reset.
