Basic engine parameters
Standard Feature
 High Exhaust System Temperature (HEST) Warning
 Fuel Density
The High Exhaust System Temperature (HEST) warning indicator allows the engine
to inform the driver when the exhaust temperature exceeds HEST Warning
Temperature Activation Limit and the vehicle speed is less than Minimum Speed for
High Exhaust Temp Warning (N065). The warning indicator will turn off once the
exhaust temperature falls below the HEST Warning Temperature Deactivation Limit.
Fuel Density (N051) allows the customer to reprogram the engine controller with a
fuel density that more precisely represents the local fuel variation used in their
vehicles, which will improve the accuracy of the controller’s calculated fuel economy.
