Temperature Alert

When the outside temperature drops to 34°F (1.7°C) or less, the ICU displays a caution text at one-second intervals for five seconds, and an audible alert sounds. Tap the mode/reset switch to acknowledge the message. The audible alert will not sound again unless the temperature cycles above 37°F (4°C) and back to 34°F (1.7°C) or less. This warning only occurs while the ignition is on and the parking brake is released.

The temperature alert message allows the driver to enable or disable the ambient temperature warning.

Press and hold the mode/reset switch to toggle between on and off. Release the mode/reset switch, then tap it to select the displayed choice.

Diagnostics

When the DIAG screen is displayed, press and hold the mode/reset switch to access the various diagnostic screens.

The diagnostic screens are used by trained technicians to retrieve fault codes and other diagnostic information pertaining to the vehicle. If active fault codes display during start-up or at any other time, make a note of the fault code and take the vehicle to an authorized Freightliner service facility

If fault codes are displayed, press and hold the mode/reset switch to view the next fault code until reaching the DIAG screen.

Engine Miles/Hours

When the engine miles/hours screen is displayed, press and hold the mode/reset switch to access the engines screen submenu.

Setup

The setup menu allows the driver to manage ICU parameters. The setup screen submenu allows the driver to enable and change service intervals.

If service intervals are enabled and service distance or time has been exceeded, the text SERVICE HOUR/MI (KM) will display at start-up to indicate vehicle service is required.

For each parameter, press and hold the mode/reset switch to navigate to the parameter change screen. In each change screen, tap the mode/reset switch to toggle between options.

The last screen in the setup menu, RESET EE, is for resetting certain parameters to the original settings. Press and hold the mode/reset switch to reset the antilock braking system (ABS), SAMs roll call, automated transmission display, transmission heartbeat, sensor fault codes, seat belt switch learning, and engine oil level.
