Factory Field Service Bulletins (FSB) could probably be reviewed from two angles – special instructions or corrections which could make the installer's life easier or factory errors/corrections which need to be highlighted. Yes – we admit the second reason is what certainly generates a majority of the FSB's and we are not perfect. From time to time, there are errors and we use this vehicle, along with Technical Helps, to immediately communicate corrections or new instructions to the best of our ability. We hope you will receive these as our continued best effort to keep you informed and to allow you to correctly apply the information.
This is not a history file list but recent items which we feel should be highlighted. If you have discovered other concerns or questions, please give us a call so we can provide you with additional details on other subjects.
