Circuit/System Verification (LCS)

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: There is a slight delay before the cooling fans activate.
  1. Ignition ON, command the fans ON and OFF with a scan tool. The cooling fans should respond to the commanded states.
  2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
