The Driver Information Center (DIC) is located on the instrument panel cluster above the steering wheel. The DIC comes on when the ignition is on. After a short delay the DIC will display the current driver and the information that was last displayed before the engine was last turned off.

If a problem is detected, a warning message will appear on the display. Pressing the select button on the DIC steering wheel buttons, or the trip odometer reset stem for vehicles without DIC steering wheel buttons, will acknowledge any current warning or service messages.

Some messages that your DURAMAX diesel may show are:

ELEVATED IDLE DISABLED

On diesel engines, this message will appear when the elevated idle/exhaust restrictor feature has been turned off. For more information on the elevated idle/exhaust restrictor feature, see Starting the Diesel Engine .

ELEVATED IDLE ENABLED

On diesel engines, this message will appear when the elevated idle/exhaust restrictor feature has been turned on. For more information on the elevated idle/exhaust restrictor feature, see Starting the Diesel Engine .

REDUCED ENGINE POWER

A computer monitors the operation of the electric accelerator. If the REDUCED ENGINE POWER message comes on while you are driving, the computer is indicating that your vehicle has a problem. You should take your vehicle in for service soon.
