200

This is the proper amount of voltage that should be found in a CAN Hi and CAN Lo circuit

What is 5 Volts

200

This is the typical amount of voltage that is used for Sensor Data to be sent to a Control Module

What is 5 Volts?

200

This component has been known to clog with Soot and is professionally known as the Hydrcarbon Doser Module. 

What is the 7th Injector

200

This term is used to describe a Reefer trailer capable of creating more than one "Zone" of temperatures within the cargo area

What is a Multi-Temp Reefer system

200

These 2 strokes are possible stages in the 4 stroke process when a piston reaches Top Dead Center

What is Compression and Exhaust
400

This component is responsible for eliminating repeat messages and Echoes in a CAN Bus communication system

What is a Terminating Resistor

400

This type of Sensor uses 2 wires only and get's its ground by the component it is threaded onto

What is a Temperature Sensor

400

This procedure is to be done to convert Soot to a smaller ash concentration to revive the life of the Diesel Particulate filter for prolonged use

What is a Regeneration?

400

This is the term used to describe the desired temperature requested for inside the Cargo area to be at.

What is a Set-point

400

These 2 sensors are used to determine the injector firing order while Cold Cranking a Diesel Engine

What are Cam/Crank position sensors

600

While more than one control module is operating on outdated software, this type of failure is what could happen

What is an Incompatible Software Fault

600

This type of Sensor Creates it's own voltage by use of Magnetic Induction.

What is a Speed/Position Sensor

600

This is the proper amount of Urea concentration that should be found in clean DEF

What is 32.5%

600

This type of Operator Failure conditions result in a Reefer trailer unable to maintain it's temperature

What is Side Skin/Corner Cap Damages

600

This type of fluid should NOT be used while attempting to fire a diesel engine

What is Starting Fluid/Ether

800

This problematic symptom could cause static to form in audio speakers as well as miscommunication failures within a CAN Bus System

What is Interference

800

This type of Sensor utilizes a 3 wire harness connector and is found in the engine, fuel system, exhaust aftertreatment systems, and fuel/def tanks

What is a Pressure System

800

During Regeneration, a Nox Sensor will report back as this Status to enable the technician to know that the sensor is ready to report accurately

What is Dew Point Enabled

800

This procedure is to be done during Fuel Filter replacement on a Reefer engine that requires pumping

What is Fuel Priming

800

This component failure was common among Cummins ISX engine platforms which resulting in Coolant going to the exhaust system

What is an EGR Cooler

1000

This CAN Bus configuration allows for a Central Gateway module to be connected at it's center which then spreads to each individual control module

What is a Star Point CAN Configuration

1000

In a 5 volt system, when a sensor reports 0 volts or full 5 Volts, this will illuminate

What is a Check Engine Light

1000

In the event of Diesel Fuel contamination within a DEF system, these components are to be replaced

What is "EVERYTHING"??

1000

This type of reefer engine failure will cause fault codes to display on the control module and will prevent the Diesel engine from running

What is a Low Oil Condition Fault

1000

This is the number of DEF Doser valves found in a new International S13 aftertreatment system

What is 2?
