Circuit/System Testing
WARNING: This page is about a different car, the 2008 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- Test drive the vehicle and verify that DTC P0572 does not set as current and the cruise control system is operative.
- If the specified DTC sets as current, test the brake applied signal circuit for a short to ground or an open/high resistance.
- If the circuit tests OK, replace the ECM.
