First, an FDRS session must be created on the vehicle prior to removing the faulted module. Once the session is started, run the Programmable Module Installation and replace the module only when instructed by FDRS. Installing a new module prior to starting a scan tool session may result in incomplete module configuration with DTCs U2100, U2101 and/or U2200. Once a session has been started, continue to follow normal WSM procedures to repair the vehicle.
