FAULT CODE CONDITIONS
The instrument panel provides fault code information to the operator. They consist of Engine
Control fault codes and Engine Protection fault codes. These fault codes can be ACTIVE
(currently present) or INACTIVE (not currently present).
Engine Protection fault codes consist of the following:
High Coolant Temperature = a de-rate of engine performance & a monitor display.
High Intake Manifold Temp. = a de-rate of engine performance.
High Fuel Temperature = a de-rate of engine performance.
Low Engine Oil Pressure = a de-rate of engine performance & a monitor display.
Water in Fuel = a fault code warning.
Engine Over speed = a fault code warning.
A fault code storage in the Electronic Control Module provides:
1. Trip information
2. Maintenance monitoring
3. J1939 data buss event log
4. Electronic control module internal data-plate information.
An engine warm up control adjusts for cold start up conditions:
• An increase in the low idle speed for first 20 seconds when coolant is cold.
• Fuel flow is limited at cold start up until full engine oil pressure is obtained.
