If the ECM needs to be reprogrammed, refer to Service Programming System (SPS) .
Engine Oil Life Remaining-When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed.

Turn the ignition OFF for 30 seconds.
Turn the ignition ON with the engine OFF.
Use the scan tool in order to retrieve history DTCs from all modules.
