• Lube oil temperature sensor B7.1 exceeded the limit value
  Fix: Check the operation of the cooler and fan.
• Fuel pressure sensor B34.1 at the HP fuel system experienced a pressure increase that is too low
  Fix: Check fuel reserves and supply, as well as replacement of the fuel filter if necessary.
• Faulty pressure sensor B48.1, missing oil signal, and short circuit faults in injector wiring for cylinders A2, A7, B4, A1, A6, B3, and B8
  Fix: Engine wiring check (Page 160), contact service or replace affected components (Pages 112, 160).
• Exhaust temperature sensor B4.21 violated the upper limit value
  Fix: Check individual exhaust gas temperatures and replace the engine oil filter if necessary.
• Excessive current engine power exceeding 1
  Fix: Check engine wiring and plug connections for the engine governor ECU.
• ECU voltage violations (411 - LOLO U-PDU PV-Number)
  Fix: Check power supply, engine wiring, and plug connections.
• Disruption fault in injector wiring to cylinder TO 2, TO 3, TOP 4
  Fix: Engine wiring check (Page 160), contact service or replace affected components (Pages 112, 160).
• Differential oil pressure sensors B5.1 and B5.3 exceeded the upper limit value
  Fix: Replace the engine oil filter and inspect engine wiring.
• Charge-air temperature sensor B9.1 exceeded the limit value
  Fix: Check the charge-air cooler coolant discharge and adjust as necessary.
• CAN bus to plant automation system is disrupted or defective
  Fix: Observe other messages and contact with Service if necessary.
