Chapter #43 - Detroit Diesel Electronic Control System

What is Detroit Diesel latest reprogramming and diagnostic software known as?

What version of DDEC is used with post-2010 DD-Series engines?

What is the primary function of the SRS?

How many teeth does the TRS pulse wheel have on a typical DDEC system?

Which dash diagnostic light is used to flash active DDEC fault codes in systems without ProDriver?

What is the primary objective when the progressive shifting option is selected?

When a DDEC engine programmed for ramp down as a failure strategy detects a low oil pressure condition, which dash light(s) will illuminate?

Technician A states that during an injector speed balance (ISB) test, an EHI displaying a positive value of plus 100 is likely to be defective.

Technician B states that an EHI displaying a negative value of minus 100 has no problems with fuel flow. Who is correct?

Which was the first computer controlled, truck diesel engine to be manufactured in North America?

When an idle speed balance (ISB) test is run on a DD-Series engine and one injector displays a high negative value, which of the following is the likely cause?

What does the injector response time (IRT) allow DDEC electronics to do when managing pulse width in EUI-fueled engines such as the Series 60?

When an idle speed balance (ISB) test is run on a DD-Series engine with ACRS and one injector displays a high positve value, which of the following is the likely cause?

Which sensor is used to signal engine position by camshaft location and confirm the crank position signal in a DDEC Series 60 engine?

In current Detroit Diesel DDEC managed engines, which controller module has an address on the J1939 data bus?

In current Detroit Diesel DDEC managed engines, which controller module is responsible for actuating fuel injection operations?

Which version of DDEC replaced the 2007 release of DDEC VI?

What online service information software must be used when working with current Detroit Diesel engines?

What software is required to troubleshoot and reprogram current Detroit Diesel engines?

Which of the following is the current DDEC term for the programming required to balance injector fuel flow variables?

The CEL and SEL both illuminate while a DDEC managed engine is being operated on the highway.

Which of the following is also likely?

In the DECVI management system, which module uses the MID 128 address on the chassis data bus?

Which of the following versions of DDEC uses a two module system?

The reason for programing DDEC ECM with IQCC is to:

Where is the EDU located on a 2007 Series 60 engine?

Technician A states that one of the reasons DDEC VI electronics uses a two module system is that the electronic management system is also used on three engines with different fuel systems. Technician B states that in DDEC 10 the injector drivers are located in the MCM. Who is correct?

What do DDEC electronics use as the for determining the rate of EHI fuel flow compesation required as a result of idle speed compesation (ISC) analysis?
