Description of Change: New software for certain C280 Marine Engines. The following updates are included into the new software:

  • Corrected overwritten rating number on backup ECM

  • Accurate fuel consumption parameter values

  • Air shutoff position switch only indicates status of air door

  • Turbocharger speed differential diagnostic only defaulted for engines with wastegate

  • Prelube satisfied condition is appropriately tied to SPN for "Engine oil priming state"

  • Wastegate only operated by the ECM control, which eliminates false codes for wastegate circuit

  • Corrected condition that gave RPM value with engine stopped

Adaptable To: Refer to Table 1 for the correct part number.
