New Engine Software is Now Used on Certain C32 Marine Engines {1901, 1920}
- Generator Set:
- C32 MAR GS ENG (S/N: RNX1-UP)
- Marine Engine:
- C32 MARINE GS (S/N: RNF1-UP)
Description of Change: Low Fuel Pressure trip point maps were not properly interfaced when the PMS is configured to "ON" on certain C32 marine engines.
Adaptable To: Low Fuel Pressure trip point maps are now correctly interfaced when PMS is configured to "ON". The change was made in Cat® ET Version 2013B. Always use the most recent version of Cat® Electronic Technician (ET) when connecting to the engine.
The software changes correct the following issues:
- KVA and KW values are displayed the same in Cat® ET.
- Load feedback value calibrated was resetting to default on each power cycle.
- Coolant level status was broadcasting over J1939 as 100% for "LOW" and 0% for "OK" in Cat® ET.
- Shutdown events were not disabling injections.
- The "Overspeed Verify" test was not functioning through J1939 (MPD) commands.
- When the right exhaust temperature sensor is not installed, Cat® ET was showing the value as ZERO on J1939 instead of "Not Available". The new software provides a sensor check for the right exhaust temperature sensor and shows "Not Available" when the sensor is not installed.
- When a diagnostic or event occurs for a few sensors (aftercooler coolant level, oil temp, intake manifold temp, exhaust temp, engine speed sensor, electrical system voltage, and personality module), the respective SPN - FMIs were not broadcasting over J1939.
