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.
IMPORTANT: Repair any Brake System related DTCs or symptoms before using this diagnostic.
IMPORTANT: This DTC may be stored as a history DTC without affecting the operation of the ECM. Do not replace the ECM if this DTC is stored only as a history DTC and is not retrieved as a current DTC.
  1. Cycle the ignition, apply and release the brake pedal. Using a scan tool, verify that DTC P0703 does not set as current in the ECM.
    • If DTC P0703 sets as current in the ECM, replace the ECM.
  2. If all circuits test normal, the system is OK. Do not replace the ECM.
