New Engine Software Is Used on Certain 3406 and C18 Marine Engines {1920}

Usage:

3406B 6TB
Engine:
C18 (S/N: TNA1-UP; GTB1-UP; JLE1-UP; T2R1-UP; GEX1-UP)
Marine Engine:
C18 MARINE (S/N: JHL1-UP; DTP1-UP)
Engine News, SEBD9989, 01 May 2015, "New Engine Software Is Used on Certain 3406 and C18 Marine Engines". Disregard the previous article. That article that follows has been updated for serial number effectivity.

Description of Change: The software allows low oil pressure shutdown fault E360(3) to clear on power cycle or a DM11 reset. Resolved the issue with the engine RPM getting stuck at 1000RPM in the cylinder cutout test on JLE prefix engines.

The software will stop the broadcasting of the turbocharger SPN's on the data link that were showing up on the engine control module.

Adaptable To: The new software group will correct the PMS bit setting on low-pressure shutdown. The new software is adaptable back to the first production of the above listed engines.

Software added delay monitoring oil pressure to 10 seconds after startup and a correction to torque speed control on GTB, GEX, JHL, and DTP prefixes.

Oil filter differential pressure measurement of 120 kPa (17.4 psi) error eliminated. Increased the fuel pressure sensor measurement range on J2-94 (P792) from 924 kPa (134 psi) to 1034 kPa (150 psi). Increased the high fuel filter restriction pressure default setting from 140 kPa (20 psi) to 240 kPa (34.8 psi), with a 0 to 500 kPa (72.5 psi) adjustable range. This action applies to GTB, GEX, JHL, DTP, TNA, and T2R prefixes
