Circuit/System Testing

WARNING: This page is about a different car, the 2007 Saturn Outlook. However, it is still accessible from the selected car via links, so may be relevant.
  1. With a scan tool, recalibrate the BPP, clear all DTCs and operate the vehicle within the Conditions for Running the DTC.
    • If DTC P0572 resets as current, test the stop lamp switch signal circuit for a short to ground.
  2. If circuits test OK, replace the ECM.
