This may be due to the DSP. To determine if the DSP is the root cause, remove the DSP fuse from the battery junction box (BCMC fuse F40 for Aviator, BCMC fuse F138 for Nautilus, BJB fuse F5 for Navigator). Inspect the fuse for an open and make sure the fuse has proper blade contact. After one minute, reinstall the good fuse. If the concern is still present or a fuse concern is found, refer to Workshop Manual (WSM), Section 415-00 for normal diagnostics. If communication has been re-established with the DSP, install a new DSP ordered from Ford Component Sales using the On-Line 1878 form to correct this condition.
