Mercury V8 300 User Manual

Mercury UFC List
The following table lists every fault currently (as of this writing) enabled on Mercury V6 and V8 4‑stroke outboard engines. Not
all faults will apply to every model. The faults are presented in the order of their Mercury universal fault code (UFC). The
columns contain the following information:
• Fault (first half of the UFC)
• Code (3 or 4 digits)
• Description (as presented in CDS G3)
• Failure (second half of the UFC)
• Code (1 or 2 digits)
• Description (as presented in CDS G3)
• PCM Fault Name ‑ The full fault name, as displayed in CDS G3. The fault descriptions and resolutions in this section are
listed alphabetically by this name.
