GM Service Manual Online

Driver Information Center (DIC) Pickup Models Only

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 some current warning or service messages.

Some messages that your DURAMAX diesel may show are:

ELEVATED IDLE OFF

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 ON

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.

WATER IN FUEL

This message will come on to warn you if there is water in the diesel fuel system. For more information on how this message works, see Diesel Fuel Requirements and Fuel System .

FUEL FILTER LIFE ###%

This feature is available on vehicles with steering wheel controls. When the fuel button is pressed and FUEL FILTER LIFE appears on the display, this information will give the percentage of fuel filter life remaining.

FUEL FILTER LIFE RESET

This message will appear when a reset is performed either by using the steering wheel controls or the following manual procedure.

For vehicles with steering wheel controls, press and hold the select button for five seconds while the FUEL FILTER LIFE message is displayed. This message will appear on the DIC for ten seconds.

For vehicles without steering wheel controls, do the following:

  1. Without pressing the pedals, turn the ignition key to the on position without starting the engine.
  2. Wait five seconds.
  3. Completely press the brake and the accelerator pedals simultaneously and hold for ten seconds. The system is now reset.
  4. Turn the ignition key off.

The next time the engine is started, the message will no longer be displayed. Always reset the FUEL FILTER LIFE system after a fuel filter change.
