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

The component information label 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 component information label is at-tached to the inside of the glove box; another copy isinside the rear cover of the Owner’s Warranty Infor- mation for North Ame rica booklet. An illustration ofthe label is shown in Fig. 1.1.

Component GWR LabelThe component GWR label is located on thepassenger-side B-pillar. The label provides maximumGWR ratings for each component.

See Fig. 1.2 for a typical component GWR label.

Federal Motor Vehicle SafetyStandard LabelsNOTE: Due to the variety of Federal Motor Ve-

hicle Safety Standard (FMVSS) certification re-quirements, not all of the labels shown will applyto your vehicle.

Tractors with or without fifth wheels purchased in theU.S. are marked as certified by means of an FMVSScertification label. See Fig. 1.3. This label is attachedto the driver-side B-pillar, as shown in Fig. 1.4.

The tire and rim portion of the FMVSS certificationlabel certifies suitable tire and rim combinations thatcan be installed on the vehicle, for the given grossaxle weight rating. Tires and rims installed on thevehicle at the time of manufacture may have a higherload capacity than that certified by the tire and rimlabel. If the tires and rims currently on the vehiclehave a lower load capacity than that shown on thetire and rim label, then the tires and rims determinethe load limitations on each of the axles.

Trucks built without a cargo body that are intendedfor service in the U.S. have an incomplete vehiclecertification label attached by the final-stage manu-facturer. See Fig. 1.5. This label will be attached tothe incomplete vehicle document included with the

vehicle, and certifies that the vehicle conforms to allapplicable FMVSS regulations in effect on the date ofcompletion.

Canadian Motor Vehicle SafetyStandard LabelsIn Canada, tractors with fifth wheels are marked ascertified by means of a statement of compliance labelwith the Canadian National Safety Mark attached tothe driver-side door frame B-pillar. See Fig. 1.6.

Trucks built without a cargo body and tractors builtwithout a fifth wheel that are intended for service inCanada have an incomplete vehicle certification labelattached to the driver-side B-pillar. After completionof the vehicle, a complete certification label must beattached by the final-stage manufacturer to certifythat the vehicle conforms to all applicable CanadaMotor Vehicle Safety Standard (CMVSS) regulationsin effect on the date of completion.

Emissions Labels

Aftertreatment System IndicatorsLabel

Engines and vehicles manufactured after December31, 2006 and domiciled in the U.S. or Canada arerequired to meet all EPA regulations effective as ofthe vehicle build date, and are equipped with anemission aftertreatment system (ATS). Vehicles do-miciled outside of the U.S. and Canada may nothave aftertreatment equipment, depending upon localstatutory emissions guidelines. See Table 1.1.

When trailer air and electrical connections cannot bereached conveniently from the ground, Federal MotorCarrier Safety Regulations require commercial carri-ers to provide back-of-cab access.

Optional grab handles are mounted either on bothcab sidewalls, or on the left sidewall only. See

Fig. 2.7. Steps are mounted either on the fuel tank(s)or on metal brackets. When a deck plate is neces-sary, it is mounted across the top of the frame rails.

IMPORTANT: Climb onto, and down from, back-of-cab access facing in toward the vehicle, asyou would on a ladder. Do not climb up or downfacing out away from the vehicle.

WARNING

Wet or dirty shoe soles greatly increase thechance of slipping or falling. If your soles are wetor dirty, be especially careful when climbingonto, or leaving, the back-of-cab area.

Always maintain three-point contact with the

back-of-cab access supports while entering andexiting the back-of-cab area. Three-point contactmeans both feet and one hand, or both handsand one foot, on the grab handles, steps, anddeck plates. Other areas are not meant to sup-port back-of-cab access, and grabbing or step-ping in the wrong place could lead to a fall, andpersonal injury.

1. Grasp the sidewall grab handle with both hands.

2. Step one foot at a time onto the top step.

3. Move your upper hand to a lower position on thegrab handle.

4. Move one foot to the bottom step.

5. Move your upper hand to a lower position on thegrab handle.

6. Step to the ground with your upper foot first.

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 Hood

1. Apply the parking brakes.

2. Release both hood hold-down latches by pullingthe ends outward.

CAUTION

Do 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, slowlytilt the hood until the straps support it. SeeFig. 2.8.

To Return the Hood

1. Grasp the grab handle, and lift the hood a just-over-center position.

2. As the hood goes over center, the hood dampercontrols the rate of descent to the operating posi-tion.

3. Make sure the hood is flush with the cowl, then

secure the hood by engaging both hood hold-down latches.

IMPORTANT: Make sure that both hold-downlatches are fully engaged before operating thevehicle.

Electrical Power DistributionElectrical power distribution provides battery power tothe electrical and electronic systems. See Fig. 3.1 forpower distribution component locations.

The following components make up the power distri-bution system:

• MEGA Fuse Junction Block (MFJB), EPA07only

• Powertrain Power Distribution Module(PT-PDM)

• Powernet Distribution Box (PNDB), EPA10 andnewer

• Cab Load Disconnect Switch

• Auxiliary PDM

MEGA Fuse Junction Block, EPA07

On EPA07 vehicles, the MFJB distributes batterypower to the alternator, SAM cab, SAM chassis, andpowertrain PDM. Battery power may also be routedto an inverter and a trailer PDM. The MFJB housesup to five MEGA fuses, and is located on the leftframe rail in front of the batteries. See Fig. 3.2.

Powernet Distribution Box, EPA10

and NewerThe PNDB distributes battery power to the SAM cab,SAM chassis, powertrain PDM, and other keep-alivecircuits.

The PNDB is mounted in the engine compartment onthe frontwall near the steering column. The label onthe PNDB fuse cover identifies typical circuits. SeeFig. 3.3.

Power Distribution Modules

Powertrain PDM

The powertrain PDM contains fuses and relays thatprovide battery and ignition power to the engine, af-tertreatment device, transmission, and otherpowertrain-related circuits. It is mounted in the en-gine compartment, above the driver-side innerfender.

Auxiliary PDM

The optional auxiliary PDM is used when additionalcircuit protection is needed for optional features. Forexample, if a beacon light is added to the Cascadia,it may require an auxiliary PDM. The auxiliary PDMmay contain fuses and relays for these devices. It ismounted in the cab, behind the doghouse cover.

Trailer PDM

The optional trailer PDM, mounted on the frame rail,is used to supply trailer power to the chassis-mounted trailer receptacles. The SAM chassis sup-plies control signals to the relays in the trailer PDM.

SAM CabThe SAM cab is located behind the glove box insidethe vehicle cab. See Fig. 3.4. The SAM cab containsfuses and relays in addition to solid state circuit pro-tection devices that will trip when a circuit is over-loaded.

Refer to Chapter 25 for fuse and relay locations.

SAM Chassis

The SAM Chassis is located in the engine compart-ment on the driver-side frontwall. See Fig. 3.3. TheSAM chassis contains fuses and relays in addition to

solid state circuit protection devices that will tripwhen a circuit is overloaded.

Refer to Chapter 25 for fuse and relay locations.

Circuit Protection Features

The SAM chassis and SAM cab may be equippedwith self-resetting circuit breakers instead of fuses.Self-resetting circuit breakers are tripped when theyreach 170°F (77°C), then self-reset once the tem-perature drops sufficiently. When the circuit overloadis removed, this circuit protection will self-reset.Some of these circuits require the ignition switch tobe cycled off then back on again for the self-reset to

occur.Some ECU’s are equipped with a self-resetting circuitbreaker removal tool.

WARNING

Always wear heat-protective gloves when han-dling a self-resetting circuit breakers, which can

Electrical System

reach extremely high temperatures. Failure to useappropriate heat protection can lead to seriousinjury.

NOTICE

Self-resetting circuit breakers can be perma-nently damaged if improperly handled. Use theguidelines below to handle them safely.

• Disconnect the batteries before removing aself-resetting circuit breaker.

• Use a circuit breaker removal tool to remove aself-resetting circuit breaker. See Fig. 3.5. Useof any other tool, including pliers, may damage

the circuit breaker.

• Never attempt to probe a self-resetting circuitbreaker while installed on the SAM Cab orSAM Chassis. Remove the circuit breaker first,or use a non-contact infrared thermometer tomeasure temperature.

Cab Load Disconnect Switch

WARNING

Turning the cab load disconnect switch (CLDS) tothe off position does not disconnect the connec-tion between the battery and the starter. To workon the vehicle safely, the negative leads must bedisconnected from the battery.

IMPORTANT: The ignition should be turned offbefore turning the CLDS to on or off.

The CLDS is used to avoid excessive draw on thebattery when the vehicle is parked for an extendedperiod of time by disconnecting (or opening) the con-nection between the battery and the most of the ve-hicle electrical system.

The CLDS may be mounted:

• inside the cab on the outboard side of the driv-er’s seat;

• at the battery box;

• outboard on the left frame rail.

See Fig. 3.6 for an EPA07 CLDS; see Fig. 3.7 for anEPA10 and newer switch.

If the CLDS is turned to the off position while the ve-hicle is running, the emergency power system willactivate. The powertrain PDM will receive power fromthe emergency power feed, but the batteries will notbe charging. See the Emergency Power Supplyheading below for details.

Emergency Power SupplyThe Cascadia electrical system has an emergencypower circuit that supplies battery power for exteriorlighting. This assists vehicle visibility in the event aMEGA fuse is open circuit. The emergency powercircuit is live even when the CLDS is turned off.

The emergency power supply feature allows for the

vehicle to be driven off the highway and for the exte-rior lighting to remain on in the event of a SAM Cabor SAM Chassis failure. The emergency power sup-ply will cause certain exterior lamps to flash (depend-ing on if it is the SAM Cab or SAM Chassis thatfailed), indicating that the vehicle is disabled.

SAM Cab Fault

If the emergency power supply system activates, donot shut down the engine until the vehicle is in a safeposition to do so. It will not be able to be restarteduntil the problem is corrected. If emergency powermode is due to a SAM Cab fault, the gauges will be-

come unresponsive but the engine will remain run-ning until it is turned off.

When the ignition is in the ON position, the emer-gency power supply will cause the following lamps toflash:

• dash panel lights

• clearance lights

• front marker lights

• side marker lights

• trailer taillights

•

rear stop lights

SAM Chassis Fault

The engine may be able to be restarted when theSAM Chassis fails. When the ignition is in the ONposition, the emergency power supply will cause thefollowing lamps to flash:

• dash panel 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

Progressive Low Voltage

DisconnectThe progressive low voltage disconnect (PLVD) fea-ture protects the batteries from excessive dischargeby disconnecting certain circuits from battery powersupply. This allows the batteries to maintain accept-able charge to restart the vehicle.

When battery voltage drops below a predeterminedvalue, loads designated as comfort loads (priority

22/232

level I) are shut down first. Then loads designated ashouse loads (priority level II) are shut down. If neces-sary, basic loads (priority level III) are shut down last.

PLVD allows the driver to continue using criticalloads, while noncritical loads are temporarily unavail-able. Calculations for disconnecting loads are basedon battery voltage, ignition switch status, and enginerpm. Also, a time delay is implemented for the shut-down and reactivation of loads to avoid unnecessarycycling of loads when battery voltage is close toshutdown thresholds.

One minute before the comfort loads or house loadsare shut down, the alarm in the instrument cluster

beeps. No alarm sounds before basic loads are 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.

Instrumentation Control UnitsThe instrumentation control unit (ICU) provides thedriver with engine and vehicle information. It is com-prised of standard and optional gauges, an audiblewarning, a driver message center, and a lightbar con-taining warning and indicator lamps (also known astelltales). Warning and indicator lamps illuminate inred (danger), amber (caution), green (status advi-sory), or blue (high-beam headlights active).

Cascadia vehicles are equipped with an ICU3, ICU4,ICU4M, or ICU4Me. See Fig. 4.1, Fig. 4.2, andFig. 4.3 for typical ICU layouts.

The following headings in this chapter provide addi-

tional information and operating instructions for ICUcomponents:

• "Warning and Indicator Lights"

• "Instruments"

• "Driver Message Center"

Ignition Sequence

When the ignition is turned on, the ICU runs a self-check. See Fig. 4.4. Observing the ignition sequenceis a good way to ensure the ICU is functioning prop-erly.

IMPORTANT: Do not crank the engine until theICU self-check is complete.

NOTE: Air gauges do not complete a sweep oftheir dials during the ignition sequence.

When the ignition is turned on, the following actionsshould occur:

• electronic gauges complete a full sweep oftheir dials

If air pressure falls below minimum pressure, thebraking ability of the vehicle will be limited. Slowthe vehicle down and bring it to a gradual stop.Do not attempt to move the vehicle until air pres-sure has risen above the minimum level. Movinga vehicle without adequate braking power couldcause an accident resulting in personal injury ordeath.

Air pressure gauges register the pressure in the pri-

mary and secondary air systems. Normal pressure,with the engine running, is 100 to 120 psi (689 to827 kPa) in both systems.

A low-air-pressure warning light and audible alert,connected to both the primary and secondary sys-tems, activate when air pressure in either systemdrops below approximately 70 psi (483 kPa).

When the engine is started, the warning light andaudible warning remain on until air pressure in bothsystems exceeds minimum pressure.

Speedometer

Two speedometer options are available. The U.S.version of the speedometer registers speed in bothmiles per hour (mph) and kilometers per hour (km/h),with mph in larger numbers. The metric version ofthe speedometer face reverses this arrangement,with km/h in larger numbers.

Tachometer

The tachometer indicates engine speed in revolutionsper minute (rpm) and serves as a guide for shiftingthe transmission and keeping the engine in the ap-propriate rpm range. For low idle and rated rpm, seethe engine identification plate.

Transmission Fluid TemperatureGauge

The transmission fluid temperature gauge indicatesthe transmission lubricant operating temperature.Temperatures vary by application, but the transmis-sion fluid temperature gauge reading should not ex-ceed 250°F (121°C).

NOTICE

A sudden increase in transmission fluid tempera-ture that is not caused by a load increase mayindicate mechanical failure. Bring the vehicle to asafe stop and investigate the cause to preventfurther damage. Do not operate the vehicle untilthe cause has been determined and corrected.


Turbocharger Boost Pressure GaugeA turbocharger boost pressure gauge indicates thepressure in the intake manifold, in excess of atmos-pheric pressure, being created by the turbocharger.

Voltmeter

The voltmeter indicates the vehicle charging systemvoltage when the engine is running and the batteryvoltage when the engine is off. By monitoring thevoltmeter, the driver can stay aware of potential bat-tery charging problems and have them fixed beforethe batteries discharge enough to create starting diffi-culties. Cascadia vehicles are equipped with either avoltmeter gauge, or a digital voltmeter readout lo-cated on the bottom line of the dash message center.

The voltmeter will normally show approximately 13.7to 14.1 volts when the engine is running. The voltageof a fully charged battery is 12.7 to 12.8 volts whenthe engine is off. Battery voltage under 12.0 volts isconsidered a low battery, and a completely dis-charged battery will produce only about 11.0 volts.

If the voltmeter shows an undercharged or over-charged condition for an extended period, have thecharging system and batteries checked at an autho-rized Freightliner service facility.

On a vehicle equipped with a battery isolator system,the voltmeter measures the average voltage of all thebatteries when the engine is running. When the en-gine is off, the voltmeter shows only the isolated bat-tery voltage and does not indicate the voltage of theengine-starting batteries.

Driver Message Center

ICU3/ICU4

The driver message center is controlled using themode/reset switch, located on the right side of theICU, and the + and – buttons mounted in the right-hand pod of the steering wheel (Fig. 4.9).

The driver message center is divided into four sec-

tions. The odometer and cruise control status fieldare displayed along the bottom of the message cen-ter. When cruise control is active, the cruise controlstatus field displays relevant cruise control icons andthe set speed. If the vehicle is equipped with amanual transmission, time and temperature are dis-played in the top left corner of the driver messagecenter. The message field displays the drivingscreens and alert messages. See Fig. 4.21.

If the vehicle is equipped with an automated trans-mission, the gear display is located in the top leftcorner of the driver message center. Time and tem-perature are displayed in the message field, unlessan alert message is active or a driving screen hasbeen selected. The odometer and cruise control sta-tus field are displayed along the bottom of the mes-sage center. See Fig. 4.22. For information abouttransmission display options, see Chapter 15.

Alert MessagesAlert messages are displayed in the message field tonotify the driver when certain conditions occur. Theyinclude warnings, cautions, and other messages thatrequire the driver’s attention. Not all alert messagesare critical to the operation of the vehicle. More im-portant messages take priority over less importantmessages.
