TICO Document #: SFN-20240830A
Units Affected: On road units with 621449 dash harness.
Information Notice
On on-road units with Dash harness 621449, we have found that the F4 fuse is marked as Spare (Cigar), as shown on the attached harness diagram. This fuse supplies power to the Actia speedometer. If the fuse is removed, the speedometer will not function. Engineering has been notified of the discrepancy in future build corrections. However, units in the field still may run into issues if drivers pull this fuse.
