Conditions for Running the DTC

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

The CAN circuits are monitored continuously by the modules on the circuit. The only requirement is that the modules are in a RUN power mode.
