ICU4M

Functions

Main features of the ICU4M include:

• Gauges that sweep 270 degrees and have pointers lit by an LED.

• Service intervals that are programmable via the keypad.

• An audible warning and alert message to warn the driver if the door is opened without first setting the parking brake.

• A flashing alert message that appears on the driver message center in low engine oil pressure or high coolant temperature conditions.

With the parking brake off, only the odometer and alert screens will display. Park the vehicle and set the parking brake to access additional screens.

The dash message center displays alert screens when certain conditions occur. They are warnings, cautions, or other messages that require the driver's attention, but not all of them are critical to the operation of the vehicle. Warning messages always display at full brightness.

More important messages take priority over less important messages. The order of priority is:

1. parking brake set (with the vehicle moving)

2. parking brake off (with the door open)

3. low oil pressure or high coolant temperature

4. hard brake warnings (if equipped with roll stability advisor)

5. low battery voltage

6. turn signal on

7. service warnings

8. no datalink activity

Alert Screens

Parking Brake On

This warning message and an audible warning come on whenever the parking brake is applied and the vehicle is moving faster than 2 mph (3 km/h). The screen and audible warning go away only when the parking brake is released, or speed is reduced below 2 mph.

Low Oil Pressure

This warning message and an audible warning come on whenever the oil pressure falls below the minimum oil pressure, whether the vehicle is idling or in motion. Tap any key to dismiss the message.

If the fault is still active 30 seconds after the message is dismissed, the warning message will come on again.

High Coolant Temp

This message and an audible warning come on whenever the engine coolant temperature exceeds the maximum allowable temperature.

If the fault is still active 30 seconds after the message is dismissed, the warning message will come on again.

Low Voltage

On some vehicles, this optional message and an audible warning come on whenever the ICU detects a low voltage condition.

Turn Signal On

This warning message and audible warning come on whenever the turn signal remains on for four minutes or five miles of travel.

To dismiss this message, either turn off the turn signal or tap any key.

Service Warnings

Service warning screens display during the ignition sequence and indicate that a service interval has been reached or exceeded and maintenance is required. The messages may indicate the number of miles (KM) or hours until the next required service or, once passed, the number of miles (KM) or hours ago that maintenance should have been performed.

Automated Transmission Display

The ICU4M can display current gear information for vehicles with an automated transmission. The last three digits at the far right on the lower line of the driver display screen are reserved for this information.

If there is a request to shift, an up or down arrow is also displayed, depending on the shift direction.

On vehicles with conventional manual or automatic transmissions, the gear and shift direction are not displayed. For more information about specific models of automated transmissions, see Freightliner SmartShift Shift Control.

• Trip advisory

• Leg distance/hours

• Leg advisory

• Outside air temperature

• Fuel used/average MPG (KM/L)

Stationary Screens

The following screens are available when the parking brake is on (when the vehicle is stationary).

• Odometer

• Trip information including trip miles/hours, idle hours, average speed, leg miles/hours

• Fuel information including fuel used, fuel economy, idle/PTO fuel usage

• Engine information including engine miles/hours, engine/PTO gallons, oil level
