Switched Sink Driver Output Pinout Specifications

Applications

The Switched Sink Driver Output Pinout type sinks an OEM-supplied load, which are typically dashboard

lamps. The Pinout is connected to one side of the OEM load. A voltage source, typically Vbatt+, is connected

to the other side of the OEM load.

Operation

The Switched Sink Driver Output Pinout can exist in one of two states: Sink (low impedance) or Off (highimpedance). These states are dictated by a microprocessor-controlled FET switch.

Sink State - Pinout Voltage can be measured at the pinout with respect to ECM ground. When the FETswitch is opened, Pinout Current is present through the pinout by way of the FET switch. Load Resistancecan be measured between the pinout and the OEM voltage source. The OEM load is on or energized.

Off State - When the FET switch is closed, some leakage Pinout current is still present by way of the 47Kresistor. The OEM load is off or de-energized.

Section III: Relays

Low Idle Shutdown Relay

The Low Idle Shutdown relay removes power from high-current machine devices when the engine is shut down

by the Low Idle Shutdown feature. This feature shuts down the engine in the presence of excessive engineidling with no operator interaction, in the effort to increase fuel economy. When shutdown occurs, battery drainmay occur because the engine is stopped but the keyswitch is on. To reduce battery drain, the Low Idle

Shutdown relay disconnects power from high-current devices such as the HVAC blower. The relay is usuallyinstalled on the fuse panel.

The Low Idle Shutdown relay has two states, poweredand shutdown. When the relay is in the poweredstate, the engine is keyed off, running, or in any condition other than a shutdown condition initiated by the LowIdle Shutdown feature. The relay is de-energized, high-current devices receive electrical power through

normally closed contacts of the relay. When the relay is in the shutdownstate, the engine has been shutdown by the Low Idle Shutdown feature. The relay is energized, the high-current devices are unpowered. Therelay remains in this state until the keyswitch is turned o f for the engine is cranked for restart.

Intake Air Heater Relay (Grid Heater)

Applications

The Air Heater relay controls operating power to an OEM-supplied grid heater. The grid heater heats the intake

manifold immediately before and after the engine is started, which improves cold engine starting and reduceswhite smoke. The grid heater is automatically activated by the Intake Air heater feature when the engine iscold. The Intake Air Heater relay is normally installed in the engine compartment.

The Intake Air Heater relay has two states, heator o f f. Intake manifold heating will occur immediately beforeand after engine start depending on a combination of intake manifold temperature and coolant temperature.

When intake manifold heating is required, the relay assumes heat. Operating power is applied to the gridheater through normally open contacts of the relay. When intake manifold heating is no longer required, therelay assumes o f f. Operating power is removed from the grid heater.

Section IV: Switches

Switch Conventions

Introduction

This document has standardized the manner in which switches are defined in order to promote maximumcomprehension of the switch requirements. There are two features of every switch, configuration andcharacteristics. Each feature may be described for a switch using words or symbols. This document uses both

methods.

Switch Configuration

A switch configuration is the number of poles and the number of throws. Poles are the number of electrically

independent switch contacts that are simultaneously switched. Throws are the number of switch positions thatresult in a switch contact.

Descriptions - When defining switch configuration by words, the number of poles are indicated by prefix (Sfor single, D for double, 3,5,etc.) followed by the letter P. The number of throws is indicated by the sameprefixes, followed by the letter T. For example, a single-pole, double-throw switch is written as SPDT.

Symbols - When defining switch configuration using a picture, the number of poles are indicated by thenumber of switch wipers connected by a dashed line. The number of throws are typically indicated by thenumber of terminals (numbered open circles) to which a wiper connects.

Switch Diagram Legend

Switch Characteristics

A switch characteristic is the contact and action at each switch position. Contact is whether the switch position

makes or breaks an electrical connection at that position. Action is whether the switch position is momentary orlatched.

Descriptions - When defining switch characteristics by words, contact is indicated by an onor an o f fwhich is supplied for each switch position. Momentary action is indicated by parenthesis around (on) or(off); latched action is indicated by an absence of parenthesis

Symbols - When defining switch characteristics by pictures, contact is indicated if a terminal (numberedopen circle) is present at that switch position. Momentary action is indicated by a filled triangle at thatswitch position; latched action is indicated by a filled circle at that switch position.

Alternate Droop Switch

Application

The Alternate Droop switch selects different droop characteristics for the High Idle Governor feature or the All

Speed Governor (ASG) feature or both. This is desirable when the machine is transitioning to a different modeof operation, for example from loading to hauling. The transition may be performed by any dedicated switchcontacts, including a relay or a manual operator switch. Installation depends on the type of switch that is used..

Alternate Low Idle Switch

Application

The Alternate Low Idle switch selects a different low idle engine speed. A higher low idle engine speed is

useful for warming up the engine, or when an application operates the engine on low idle governor. Thealternate low idle engine speed may be selected by any dedicated switch contacts, including a relay or amanual operator switch. Installation depends on the type of switch that is used.

Operation

The Alternate low Idle switch has two positions, base low id leor al ternate low id le. The switch operates inthe Normal or Transition mode depending on an optional customer selection.

Normal Mode - When the switch is in the base low id leposition, the engine's low idle speed is defined bythe Low Idle Governor feature. When the switch is in the al ternate low id leposition, engine low idle speed

is instead defined by the Switchable Low Idle feature.

Transition Mode - This mode requires a switch transition from base low id le to al ternate low id le

subsequent to key-on to select the alternate low idle. Until this transition has occurred, or when the switchis in the Base Low Idle position, engine low idle speed is defined by the Low Idle Governor feature. If the

transition has occurred and the switch is in the al ternate low id leposition, engine low idle speed is insteaddefined by the Switchable Low Idle feature.

Alternate Torque Switch

Applications

The Alternate Torque switch toggles between the normal 100% curve and up to two alternate torque curves. A

different torque curve results in an engine with different HP ratings. Different horsepower ratings are desirablewhen the same engine is used for dual modes of operation, for example hauling vs. loading. A torque curvemay be selected by any dedicated switch contacts, including a relay or a manual operator switch. Installation

depends on the type of switch that is used.

Operation without Boost Power

The following operational description applies when the Automatic Boost Power feature is not enabled. The

Alternate Torque switch has two or three switch positions (see switch diagram). When the switch is in the Lowposition, a lower calibratible torque curve is used. Engine torque is limited to the lower curve. The ECM maybe calibrated for either a Normal or Failsafe configuration of the switch.

AXG On/Off Switch

Application

The AXG On/Off switch selects operation of the Auxiliary Speed Governor (AXG), AXG is an auxiliary fueling

governor that varies engine torque in an attempt to control either shaft speed or an application-specificpressure, depending upon the engine configuration.

The AXG On/Off switch has two positions, onoro f f. When the switch is in the offposition, the engine fuelingis not controlled by the AXG. When the switch is in the on position and there are no AXG faults, engine fuelingis controlled by the AXG, permitting shaft speed control or pressure control from a commanded throttle input.

Air Conditioner Pressure Switch

Applications

The Air Conditioner Pressure switch detects air condition refrigerant pressure relative to two pressure

thresholds defined by the switch. It generates a control signal for the Electronic Fan Clutch feature which inturn operates an air conditioning condenser fan. This switch is inserted into the high-pressure side of the airconditioner refrigerant system. A hysteresis of 2-4 PSI is recommended between the two pressure thresholds

to prevent an excessive number of fan clutch state transitions.

The Air Condition Pressure switch has two positions , pressure highorpressure not h igh, and two thresholds,

upperand l owe r. On rising refrigerant pressure, the switch will transition to the Pressure High position whenpressure exceed the uppe r threshold. In this position, On/Off fan will operate at its characteristic RPM, aVariable-Speed fan will operate at selectable rpm. On falling refrigerant pressure, the switch will transition to

the pressure not highposition when pressure falls below the l owe rthreshold. In this switch position, the fandoes not operate due to refrigerant pressure. However, the fan may still run in response to some other needsuch as high coolant temperature.

Pressure Switches: Brake Switch

Description

This normally closed sing pole, single throw (SPST) plunger design limit switch is rated for one million switch

cycles. It has an actuation force of 4.17 N [0.937 lbf] (15 ounces) and the total plunger movement is 4.928 mm[0.1938 in]. The recommended switch actuation is 3.175 mm [0.1249 in] to avoid undesirable bottoming out.An elastomeric sealing boot keeps harsh abrasive from damaging the plunger body and guide. Gold contacts

make the switch reliable for low voltage and current switching.

Application

The signal from the brake pressure is used to disable cruise control and ISC operations. It is mounted directly,

or with a T-fitting, into the low pressure control side of the truck's pneumatic brake system. When the brakepedal is actuated or the trailer brake is applied, the pneumatic pressure rises from 0 psig to 90 psig. An opencircuit to the control module, whether by this switch or a wiring circuit failure, will disable the cruise control

function. This switch is qualified for under-the-dashboard mounting only. A molded rubber boot isrecommended for use with the mating connector.

Switches and Switch Assemblies: Rotary Clutch Switch Assembly

Description

The Clutch Switch Assembly is comprised of a rotary switch, lever and rod assembly and a switch bracket. The

rotary switch is a normally closed single pole, single throw switch that is designed to exceed one million switchcycles. Gold contacts make it reliable for low voltage and current switching. The shaft is 7.87 millimeters[0.309 in] in diameter. At the open position, actuation torque is 1.34 N-m [0.988 ft-lbf] (190 inch-ounces). Total

mechanical travel is 40 degrees of maximum rotation with 35 degrees of maximum pretravel and 3 degrees ofdifferential travel. The ruggedness of this switch allows it to be used in high vibration environments.

Application

The device can be mounted either in the cab or under the cab. The rod is cut or bent to fit the top or front sideof the clutch arm so that the clutch rest position has the switch in the closed-circuit mode. As the clutch pedalis depressed, the linkage arm will move and the spring preload in the switch will cause the rod to follow and

open the switch circuit. When mounted under the cab, a shield should be added to prevent direct road splashon the rotary shaft area.

Switches and Switch Assemblies: Optional Clutch Brake Switch

Description

This normally closed single pole, single throw (SPST) plunger design limit switch is rated for one million switch

cycles. It has an actuation force of 4.17 N [0.937 lbf[ (15 ounces) and the total plunger movement is 4.928 mm[0/1938 in]. The recommended switch actuation is 3.176 mm [0.1249 in] to avoid undesirable bottoming out.An elastomeric sealing boot keeps harsh abrasives from damaging the plunger body and guide. Gold contacts

make the switch reliable for low voltage and current switching.

Application

The limit switch may be closed as an optional clutch switch instead of the rotary clutch switch assembly. It is

mounted on the bell housing of the transmission and is operated by an actuating bracket attached to the bellcrank. The slim packaging of this harsh environment plunger switch allows it to be easily mounted for limitedswitch application.

SECTION V: SENSORS

Vehicle Speed Sensor (Variable Reluctance Magnetic Pickup)

Application - This sensor is mounted through the transmission case and senses passing teeth from a 16-tooth

or optional 11-tooth gear. Each revolution of the gear produces 16 or 11 cycles of quasi-sinusoidal voltage.The sensor responds down to 1 mph which is 31 rpm of the 16-tooth speedometer gear shown in the

accompanying illustration. At the time of installation, the sensor is to be hand turned until it touches the target,then backed off one-half turn and the jam nut tightened. The sensor is polarity sensitive and a sharp positive-to-negative transition is accomplished by using the white lead wire as the positive reference and the black wireas the negative reference. It can also be used as a dual output engine speed sensor, mounted through the ring

gear housing to sense ring gear teeth.

Hardware - This sensor is a single pole piece, dual output variable reluctance magnetic pickup in which each

output is physically isolated from the other. The output swings positive when the target approaches, passesthrough zero when the target and pole piece are coincident, and then swings negative when the target leaves.Voltage amplitude is a function of gap, target size and angular velocity.

ANALOG SENSORS

OEM Pressure Sensor

Application -The OEM Pressure sensor may be used to detect the pressure of any desired liquid or gas. OEM

pressure can be used to switch any device on or off, to initiate an engine shutdown, or to control a fan. OEMPressure can be governed to a reference pressure in order to drive air- or hydraulically-powered equipment.Any or all applications can be met at once. Installation varies according to application.

Operation - The OEM Pressure sensor converts detected pressure into a DC voltage. This voltage is detectedby the ECM and converted into OEM pressure using a calculation that performs a linear interpolation between

two breakpoints. OEM pressure may be used by any or all of the following features:

Auxiliary Governor - This feature converts throttle input into a reference OEM pressure. Then using afeedback loop, engine torque is varied as required to maintain this OEM pressure. Depending on the

application, OEM pressure can be maintained at a pre-selected value, or continuously variable OEMpressure control is possible.

Electronic Fan Clutch - If the fan type is Variable-Speed, OEM pressure is applied to a calibration table togenerate a characteristic PWM frequency. The fan will operate at the minimum fan speed corresponding tothe characteristic PWM frequency. If the fan type is On/Off, the fan will turn on or off when OEM pressure

transitions through a pressure threshold.

Switched Outputs - OEM pressure is one of several trigger parameters for three options: Relay A, Relay

B, and Engine Shutdown. Each option has one or more associated pressure thresholds. Depending onOEM pressure value relative to these thresholds, the OEM pressure trigger parameter is either ACTIVE orINACTIVE for each option. When the desired combination of trigger parameters is ACTIVE for the Relay A

option, that relay energizes or de-energizes. When the desired combination of trigger parameters isACTIVE for the Relay B option, that relay energizes or de-energizes. When the desired combination oftrigger parameters is ACTIVE for the Engine Shutdown option, an engine shutdown is initiated.

OEM Temperature Sensor Specifications

Application The OEM temperature sensor may be used to detect the temperature of any desired liquid orgas. The detected temperature can be used to switch any device on or off, to initiate an engine shutdown, or to

control a fan. Any or all applications can be met at once. Installation varies according to application.

Operation The OEM temperature sensor converts detected temperature into a resistance. This resistance is

detected by ECM and converted into OEM temperature using a table with 20 breakpoints. OEM temperature

may be used by either or both of the following features.

a. Electronic Fan Clutch If the fan type is variable-speed, OEM temperature is applied to a calibrationtable to generate a characteristic PWM frequency. The fan will operate at the minimum fan speedcorresponding to the characteristic PWM frequency. If the fan type is on/off, the fan will turn on or off

when OEM temperature transitions through a temperature threshold.

b. Switched Outputs OEM temperature is one of several trigger parameters for three options: Relay A,

Relay B, and Engine Shutdown. Each option has one or more associated temperature thresholds.Depending on OEM temperature relative to these thresholds, the OEM temperature trigger parameteris either ACTIVE or INACTIVE for each option. When the desired combination of trigger parameters is

ACTIVE for the Relay A option, that relay energizes or deenergizes. When the desired combination oftrigger parameters is ACTIVE for Relay B option, that relay energizes or deenergizes. When the

desired combination of trigger parameters is ACTIVE for the engine Shutdown option and EngineShutdown is initiated.
