Vehicle Specification DecalThe vehicle specification decal lists the vehiclemodel, identification number, and major componentmodels. It also lists the major assemblies and instal-lations shown on the chassis specification sheet.One copy of the vehicle specification decal is at-tached to the inside of the sliding storage/wastedrawer; another copy is inside the rear cover of theOwners Warranty Information for North Americabooklet. An illustration of the decal is shown inFig. 1.1.

NOTE: Labels shown in this chapter are ex-amples only. Actual specifications may vary fromvehicle to vehicle.

Federal Motor Vehicle SafetyStandard (FMVSS) LabelsNOTE: Due to the variety of FMVSS certificationrequirements, not all of the labels shown willapply to your vehicle.Tractors with or without fifth wheels purchased in theU.S. are certified by means of a certification labeland the tire and rim labels. See Fig. 1.2. These la-bels are attached to the left rear door post, as shownin Fig. 1.3.If purchased for service in the U.S., trucks built with-out a cargo body have a certification label attachedto the left rear door post. See Fig. 1.4. In addition,after completion of the vehicle, a certification labelsimilar to that shown in Fig. 1.2 must be attached bythe final-stage manufacturer. This label will be lo-

cated on the left rear door post and certifies that thevehicle conforms to all applicable FMVSS regulationsin effect on the date of completion.

Canadian National Safety Mark attached to the leftrear door post. See Fig. 1.5.If purchased for service in Canada, trucks built with-out a cargo body and tractors built without a fifthwheel are certified by a "Statement of Compliance"label, similar to Fig. 1.2. This label must be attachedby the final-stage manufacturer after completion ofthe vehicle. The label is located on the left rear doorpost, and certifies that the vehicle conforms to allapplicable CMVSS regulations in effect on the dateof completion.

Tire and Rim LabelsTire and rim labels certify suitable tire and rim combi-nations that can be installed on the vehicle, for thegiven gross axle weight rating. Tires and rims in-stalled on the vehicle at the time of manufacture mayhave a higher load capacity than that certified by thetire and rim label. If the tires and rims currently onthe vehicle have a lower load capacity than thatshown on the tire and rim label, then the tires andrims determine the load limitations on each of theaxles.See Fig. 1.6 for U.S. and Canadian tire and rim la-bels that are attached to the left door rear post.

EPA Vehicle Noise EmissionControl LabelA vehicle noise emission control label (Fig. 1.7) isattached either to the left side of the dashboard or tothe top-right surface of the frontwall between thedash and the windshield.

It is the owners responsibility to maintain the vehicleso that it conforms to EPA regulations.IMPORTANT: Certain Freightliner incompletevehicles may be produced with incomplete noisecontrol hardware. Such vehicles will not have avehicle noise emission control information label.For such vehicles, it is the final-stage manufac-turers responsibility to complete the vehicle inconformity to U.S. EPA regulations (40 CFR Part205) and label it for compliance.

Hood Opening and ClosingA grab handle at the front of the hood provides ahand-hold for hood tilting. Two tilt-assist struts help totilt the hood open, and to return it to the operatingposition. A damper controls the closing rate of thehood and hood straps prevent the hood from over-travel. In the operating position, the hood is securedby a hold-down latch on each side of the hood.

To Tilt the Hood1. Apply the parking brakes.2. Release both hood hold-down latches by pulling

the ends outward.

CAUTIONDo not let the hood free-fall to the full-open posi-tion. To do so could cause damage to the hoodor hood straps.3. Using the bumper step and grab handle, slowly

tilt the hood until the straps support it. SeeFig. 2.8.

To Return the Hood1. Grasp the grab handle, and lift the hood a just-

over-center position.2. As the hood goes over center, the hood damper

controls the rate of descent to the operating posi-tion.

Electrical System OverviewWARNING

Do not attempt to modify, add, splice, or removeelectrical wiring on this vehicle. Doing so coulddamage the electrical system and result in a firethat could cause serious personal injury or prop-erty damage.The Cascadia electrical system is a multiplexeddesign. Multiplexing allows the electrical system tosimultaneously perform tasks and monitor compo-nents. The multiplexing system sharply reduces thenumber of wires on the vehicle by sharing wires formultiple components. Multiple electronic messagesare sent simultaneously through the same signalpath, called the datalink.The multiplexed electrical system on Cascadia ve-hicles combines electronic devices called SAMs, withtraditional power distribution modules (PDMs) thathouse fuses and relays. The SAM Cab and SAMChassis monitor inputs from sensors and switches,and control power distribution to the electrical loadson the vehicle.

Electronic Power DistributionThe SAM Cab and SAM Chassis modules are elec-tronic control units that have power distribution com-ponents (fuses and relays) physically on them. Referto Chapter 25 for fuse and relay locations. The SAMCab is located behind the glovebox, on the passen-ger side. See Fig. 3.1.The SAM Chassis is located on the frontwall, on thedriver side. See Fig. 3.2.

Electrical Power DistributionStandard electrical power distribution provides bat-tery power to the electronics system. The electricalpower distribution components on the Cascadiavehicle are:

Powertrain PDM Trailer PDM Auxiliary PDM MEGA Fuse junction block

Main ground junction block Load disconnect switch

Powertrain PDMThe powertrain PDM provides battery and ignitionpower to the engine ECM, the exhaust aftertreatmentdevice (ATD), transmission (TCU), as well as otherpowertrain-related circuits. It is mounted in the en-gine compartment, above the quarter fender on thedriver side. See Fig. 3.2.

Trailer PDMThe optional trailer PDM mounted on the frame rail isused to supply trailer power to the chassis-mountedtrailer receptacles. The SAM Chassis supplies controloutputs to the remote trailer PDM. The trailer PDM ispowered through the vehicle battery system.

Auxiliary PDMThis optional PDM is used when additional circuitprotection is needed for optional features. For ex-ample, if a beacon light is added to the Cascadia, itmay require an auxiliary PDM.

MEGA Fuse Junction Block (MFJB)The MEGA Fuse junction block houses up to fiveMEGA Fuses. One fuse is used to provide power tothe engine and transmission, one to the SAM Cab,and one to the SAM Chassis. The remaining MEGAFuses may be used to power an optional trailer PDMand/or inverter. The MFJB is located on the leftframe rail in front of the batteries. The cab electricalsystem is fed from the battery through the MFJB re-gardless of the ignition switch position. This routingprovides the best power distribution to the vehicle.See Fig. 3.3.

Main Ground Junction Block (MGJB)The MGJB is the main node for connecting groundreturns to the battery. It is located on the left framerail, ahead of the MEGA Fuse junction block. SeeFig. 3.3.

Load Disconnect SwitchThe load disconnect switch is mounted in one ofthree locations:

inside the cab on the left side of the driversseat (left-hand-drive vehicle);

on the battery box; outboard mounted on the left frame rail.

The load disconnect switch is used to avoid exces-sive draw on the battery when the vehicle is parkedfor an extended period of time. When the load dis-connect switch is set to OFF, it interrupts the connec-tion between the battery and the MEGA Fuse junc-tion block, and disconnects circuit power at thepositive battery cable. See Fig. 3.4.

WARNINGTurning the load disconnect switch to the OFFposition does not disconnect the connection be-tween the battery and the starter. To work on thevehicle safely, the negative leads must be discon-nected from the battery.

IMPORTANT: The ignition should be turned OFFbefore turning the load disconnect switch.If the load disconnect switch is turned to the OFFpositon while the vehicle is running, the emergencypower system will activate. The powertrain PDM willreceive power from the emergency power feed onthe SAM system, but the batteries will not be charg-ing. See Emergency Power Supply, for details.

Emergency Power SupplyThe emergency power supply feature ensures that inthe event of a SAM Cab or SAM Chassis failure, thevehicle can be driven off the highway, and kept con-spicuous until help arrives. The emergency powersupply will cause certain exterior lamps to flash (de-pending on if it is the SAM Cab, or SAM Chassis thatfailed), indicating that the vehicle is disabled. SeeFig. 3.5 for identification of the exterior lights.If the SAM Cab fails, all gauges in the instrumenta-tion control unit (ICU) drop to zero because power tothe ICU is lost. Do not shut off the engine until thevehicle is safely off the highway; the engine cannotbe restarted when the SAM Cab fails.When the ignition is in the ON position, the emer-gency power will cause the following lamps to flash:

dash panel lights clearance lights front marker lights side marker lights trailer taillights rear stop lights

If the SAM Chassis fails, the turn signal indicatorswill flash alternately. The engine can be restartedwhen the SAM Chassis fails.When the ignition is in the ON position, the emer-gency power outputs will cause the following lampsto flash:

dash panel lights clearance lights identification lights front marker lights turn-signal indicators in the ICU (alternately) side marker lights rear turn-signal lights trailer taillights

If the ignition switch is turned ON while the load dis-connect switch is in the OFF position, the emergencypower supply feature will activate the followinglamps:

clearance lights (flashing) side marker lamps (flashing) low beam headlights

Powernet ManagementThe powernet management feature protects the bat-teries from discharging too much by temporarily shut-ting down loads from the power supply. This ensuresthat in the event of a drop in voltage, the batterydraining process is slowed.Progressive low voltage disconnect (PLVD) is usedto implement the powernet management feature.

When the battery voltage drops below a predeter-mined value, loads designated as comfort loads (pri-ority level I) are shut down first. Then loads desig-nated as house loads (priority level II) are shut down.If necessary, basic loads (priority level III) are shutdown last.The progressive shutdown of loads from comfortloads, to house loads, to basic loads allows thedriver to continue using critical loads, while noncriti-cal loads are temporarily unavailable. Calculations fordisconnecting loads are based on battery voltage,ignition switch status, and engine RPM. Also, a timedelay is implemented for the shutdown and reactiva-tion of loads to avoid unnecessary cycling of loadswhen battery voltage is close to the shutdown thresh-olds.

The SAM Cab reads the battery voltage via a dedi-cated sense pin that is fused in the powertrain PDMand not at the MFJB.One minute before the comfort loads and houseloads are shut down, an alarm sounds for 10 sec-onds. No alarm sounds before the basic loads shutdown.If the interior lights have been shut down by PLVD,pressing one of the interior light switches (ifequipped) brings the interior lights back on.See Table 3.1 for the type of loads shut down underspecific conditions.See Table 3.2 for the loads that are designated com-fort, house, and basic load status.

ICU3-P3 (InstrumentationControl Unit)See Fig. 4.1 for a typical layout of the ICU3-P3.The ICU3-P3 receives information from various sen-sors installed on the vehicle, and feeds it to elec-tronic gauges. Only air gauges operate mechanically.There are eight standard gauges on the main instru-ment panel, and space for six optional gauges in theauxiliary gauge panel. See Fig. 4.1.The lightbar is the heart of the ICU3-P3. It houses aset of warning and indicator lights, and the driver dis-play screen.

There are four rows of warning and indicator lights inthe lightbar. Lights installed in the top row are op-tional and their positions may vary. The lights in thebottom three rows are installed in fixed positions onall vehicles. Most are standard, but a few are op-tional. See "Warning and Indicator Lights", later inthis chapter, for details.The driver message display is a one-line by seven-character liquid crystal screen (LCD) that normallyshows odometer readings, or messages that alert thedriver of situations that must be acknowledged. Italso displays features and options when program-ming the ICU.

moving at a speed of at least 2 mph (3 km/h)While the vehicle is being driven, if the outside airtemperature drops to 34F (1C) or less, the mes-sage display will flash the temperature, and a warn-ing chime will sound for 5 seconds if the ambienttemperature alarm is enabled.

ICU3-P3 Ignition SequenceIf the headlights are turned on, the driver messagedisplay shows the odometer reading until the ignitionis turned on.When the ignition is turned on, the electronic gaugescomplete a full sweep of their dials, the warning andindicator lights illuminate, and the buzzer sounds for3 seconds.NOTE: The air gauges do not sweep.The following lights illuminate during the ignition se-quence:

Fasten Seat Belt Warning Low Battery Voltage Warning High Coolant Temperature Warning Low Engine Oil Pressure Warning Low Air Pressure Warning Parking Brake On Indicator All engine warning lights, including engine pro-

tection, check engine, and (Cummins only)stop engine

All ABS warning lights, including wheel spin,tractor ABS, and (if installed) trailer ABS

See Fig. 4.2 for the ICU3-P3 ignition sequence.NOTE: The engine and ABS warning lights illu-minate during the ignition sequence, but theyare controlled by an independent ECU (elec-tronic control unit), not by the ICU3-P3.When the ignition switch is turned on, the ICU3-P3performs a self-test, and looks for active faults. Dur-ing the first half of the self-test, all segments of thedisplay illuminate as follows: "888888.8." TheICU3-P3 voltmeter display illuminates with the value

"8.8." During the second half of the self-test, the soft-ware revision level is displayed.If there are no active faults, the ICU3-P3 displays theodometer reading. However, if the ICU3-P3 has re-ceived active fault codes from other devices, it dis-plays them one after the other until the parking brakeis released or the ignition switch is turned off. Oncethe parking brake is released, the ICU3-P3 displaysthe odometer reading again.

Mode/Reset SwitchA MODE/RESET switch is located on the right sideof the ICU3-P3 instrument cluster. See Fig. 4.1. TheMODE/RESET switch is used to scroll through thescreens on the driver message display, and to resetfeatures such as trip counters, miles or kilometersunits, and the ambient temperature alarm. Pressingthe MODE/RESET button advances the display tothe next feature. Holding the button scrolls to a menuchoice, then releasing it at the preferred choice andpressing the MODE/RESET switch will reset the dis-play. When the display is reset, an audible chirp isheard.The driver message display screens can also bescrolled through using the switches mounted on thesteering wheel. See Fig. 4.3. Use the + button toscroll up, and use the button to scroll down. The +button can be be held to reset or select a menuchoice, instead of the MODE/RESET button, for anyscreen.

When the ignition sequence is completed, if the park-ing brake is released, the driver message display willcycle through the trip information screens and theambient air temperature display screen only. Theparking brake must be set to access the stationaryaccess screens, i.e. SELECT, ALERT, DIAGNOSTIC,ENGINE, OIL LVL (if available) and SETUP screens.See Fig. 4.4 for a diagram of the stationary accessscreens.

Alert MessagesWith the parking brake released, only the odometerand alerts messages can be displayed. Park the ve-hicle and set the parking brake to display additionalscreen functions.The dash message center displays alertss when cer-tain conditions occur. They appear when the parkingbrake is off, and override the regular screen display.They are warnings, cautions, or other messages thatrequire the drivers attention, but not all of them arecritical to the operation of the vehicle. Warning mes-sages always display at full brightness.More important messages take priority over less im-portant messages. The order of importance, or prior-ity, is:1. parking brake on (with the vehicle moving)2. parking brake off (with door open)3. low oil pressure, high coolant temperature4. hard brake warnings (if equipped with RSA)5. low voltage6. Caution 34F (1C) (or less); road may be icy7. turn signal on8. incoming instant or Qualcomm messages9. service warnings10. no datalink activity

"Incoming Message" AlertOn vehicles with an onboard Qualcomm communica-tions system, this screen activates whenever a mes-sage is received. "Incoming Message" appears onthe message display screen.NOTE: The "Incoming Message" screen alsodisplays during the ignition sequence if a mes-sage is available.This message displays for a preset time period andthen disappears. It returns after the preset intervaluntil it is dismissed by pressing the +, , or the MYINFO switch.

"Park Brake On" WarningThis warning message and an alarm tone come onwhenever the parking brake is applied and the ve-hicle is moving faster than 2 miles per hour. The

word "Warning" flashes on the message displayscreen above the message "Park Brake On". Thescreen and alarm tone go away only when the park-ing brake is released, or speed is reduced below 2mph (3 km/h). See Fig. 4.13.

"Low Oil Pressure" WarningThis warning message and an alarm tone come onwhenever the oil pressure falls below the minimumoil pressure specified by the engine manufacturer,whether the vehicle is idling or in motion. The word"Warning" flashes on the message display screenabove the message "Low Oil Pressure". Dismiss themessage by pressing the +, , or the MY INFOswitch.NOTE: If there is more than one alert messageto display, pressing the +, , or the MY INFOswitch takes you to the next message, and soon, until all the messages have been received.If low oil pressure is detected during the ignition se-quence, it displays as an active fault and the alertscreen does not appear.After 30 seconds, this message displays again andcan be dismissed as before by pressing the +, , orMY INFO switch.

"High Coolant Temp" WarningThis message and an alarm tone come on wheneverthe engine coolant temperature exceeds a presetpoint specified by the engine manufacturer (see theengine operation manual for this temperature). Theword "Warning" flashes on the message displayscreen above the message "High Coolant Temp".This message follows the same rules of dismissaland display as "Low Oil Pressure".

"Low Voltage" WarningOn some vehicles, this message and an alarm tonecome on whenever a low voltage condition is de-tected by the instrumentation control unit. The word"Warning" flashes on the message display screenabove the message "Low Voltage".

"Turn Signal On" WarningThis warning message and buzzer come on when-ever the turn signal remains on for 4 minutes, or 5miles of travel. The word "Warning" flashes on thedisplay screen above the message "Turn Signal On",and the buzzer sounds.To dismiss this message, either turn off the turn sig-nal, or press the +, , or MY INFO switch.

"Air Temperature" WarningWhen the outside ambient air temperature drops to34F (1C) or less, the ICU will display a warningtext at 1 second intervals for 5 seconds, and afriendly chime will sound. The driver must acknowl-edge the warning by pressing the steering wheelswitch, or the Quick Info switch. The chime will notsound again unless the temperature cycles above37F (4C) and back to 34F (1C) or less. Thiswarning only occurs while the ignition is on and theparking brake off. The outside ambient air tempera-ture will display in degrees Fahrenheit if MI is se-lected in the setup screens, or degrees Celsius if KMis selected.NOTE: The ambient air temperature warning isin the disabled state when the vehicle isshipped from the factory. It must be enabled inthe ICU setup screen.

Service WarningsService warning screens display during the ignitionsequence and indicate that a service interval hasbeen reached or exceeded and maintenance is re-quired. The messages may indicate the number ofmiles (KM) or hours until the next service or, oncepassed, the number of miles (KM) or hours ago thatmaintenance should have been performed. The mes-sages read "X Miles (KM) To Next Service", "X HoursTo Next Service", "Service Was Due X Mi (KM) Ago",and "Service Was Due X Hr Ago". The letter X repre-sents the number of miles (KM) or hours pro-grammed.

"No Datalink Activity" Alert (EPA07 only)The "No Datalink Activity" screen comes on when-ever the datalink is not receiving data.If the condition persists, take the vehicle in for ser-vice as soon as possible to discover the cause of theproblem.

Automated Manual TransmissionsDisplayThe ICU4M-P3 can display current gear informationfor vehicles with automated manual transmissions(AMT). The last 3 digits at the far right on the lowerline are reserved for this information.If there is a recommendation to shift, one digit dis-plays an arrow, either up or down depending on theshift direction. The other two digits display the cur-rent gear.On vehicles with conventional manual or automatictransmissions, these 3 digits do not display. For moreinformation about specific models of automatedmanual transmissions, see Chapter 15.

Favorite ScreenThe driver can access a preset screen using the MYINFO switch. Holding down the bottom of the MYINFO switch for 1.2 seconds will set the currentscreen as the favorite screen. A chirp will sound toverify the screen has been set. Only screens thatcan be accessed with the parking brake off, can beselected as the favorite screen.The favorite screen can be called up by pressing thebottom of the MY INFO switch. The favorite screencan be accessed with the parking brake off or on.There is no time-out for this screen. The screen canbe acknowledged with any button except the MYINFO, and it will return to the previous screen.
