May 19, 2015 Detroit Diesel Diagnostic Link 7.11 Full Crack (DDDL7.11). Welcome to the production release of Detroit Diesel Diagnostic Link software. This version is used to perform diagnostics on all. Demand a Superior Powertrain. Demand Detroit. Detroit offers a complete line of heavy-duty diesel engines, axles, transmissions, safety systems and connected vehicle services for the commercial transportation industry in both the on-highway and vocational markets.
Extractionand Analysis of Data fromCommercial Vehicle ECMsBoster,Kobayashi & Associates has acquired the hardware andsoftware to extract and analyze Event Data Recorder (EDR) dataon Detroit Diesel Corporation (DDC) Series 60 diesel engines,Mercedes-Benz MBE-900 and MBE-4000 series engines. Theseengines are in widespread use in the medium and heavy-dutytruck market, including trucks and truck-tractors manufacturedby Mack, International, Freightliner, Western Star, Sterlingand others. In addition, DDC engines are offered as standardor optional equipment by virtually every bus and coachmanufacturer in North America.
Vocational trucks, fire trucks,and luxury motorhomes also utilize these engines. The EngineControl Modules (ECMs) in use on the more recent versions ofthese engines (1998 and later) quite often contain data thatis valuable in the analysis and reconstruction of motorvehicle accidents.DetroitDiesel Corporation is a leading manufacturer of electronicallycontrolled diesel engines for the commercial vehicle market. DDCSeries 60 engines have been the #1 selling heavy-duty engine for12 years in a row. These engines are equipped with DetroitDiesel Electronic Controls (DDEC). DDEC’s primary functionsrelate to optimizing engine performance, efficiency, andemissions. It also captures and stores data used to produce awide range of diagnostic and management reports.
Beginning inlate 1997, the fourth generation DDEC systems (known as DDEC IV)included the ability to record data related to hard brake andlast stop events. DDEC V, introduced in late 2003, providessimilar data recording features.TheDDEC software, Detroit Diesel Diagnostic Link (DDDL) and DDECReports, is used in conjunction with a translator box and laptopPC to download data from the ECM. If the vehicle electricalsystem is intact post-accident, the download is accomplished byplugging into the diagnostic link connector in the cab of thetruck. If the vehicle is so badly damaged that download throughthe diagnostic link connector is not feasible, download directlyfrom the ECM is usually possible.TheDDDL and DDEC Reports software package produces a wide range ofdiagnostic and management reports. A download from a DDEC IV/VElectronic Control Module (ECM) may contain a trip activityreport, monthly activity reports (3 months), vehiclespeed/engine load/rpm data, diagnostic records, hard brakereports (last two hard braking events), a last stop record, anda daily engine usage report (30 days).
The reports most usefulin accident reconstruction are typically the Hard Brake Reportand/or the Last Stop Record.AHard Brake Report is the historical detail of the vehicles lasttwo hard braking events (Hard Brake #1 and Hard Brake #2). AHard Brake Report is triggered when the calculated vehicle speeddecreases by a user defined threshold. The default value is 7mph per second, which means that if the vehicle slows 7 mph ormore in 1 second, a Hard Brake Report will be generated. Thiscorresponds to a deceleration rate of approximately 0.32 g’s.The Hard Brake Report contains vehicle and engine operating datafor 1 minute and 15 seconds before and 15 seconds after thetrigger point. Data is captured in 1 second intervals, andincludes the data shown in Table 1.Vehiclespeed, brake and clutch status, throttle position and cruisecontrol status are particularly relevant in the reconstructionof an accident.
Hard Brake Reports also display the time anddate of occurrence.TheLast Stop Record is also useful in accident reconstruction. ALast Stop Record is triggered when the vehicle speed changesfrom the drive state (greater or equal to 1.5 mph and engine RPMgreater than zero for two seconds) to the stop state (less than1.5 mph or ignition turned off) and subsequently remains stoppedfor 15 seconds.
The Last Stop Record contains the same datashown in Table 1, but for an even greater period of time. TheLast Stop Record contains vehicle and engine data (in 1 secondintervals) for 1 minute and 45 seconds before and 15 secondsafter the last stop trigger point.Ideally,data extraction should occur immediately following an accidentand before the vehicle is restarted or moved. This is not alwayspossible, however, for the obvious reasons.

As long as thevehicle has not been driven post-accident, the data will bepreserved in the ECM. Even if the vehicle is driven (and theLast Stop Record overwritten with a new one), data may still beavailable from the Hard Brake Reports if the vehicle has notbeen subjected to two additional hard brake events. Subsequenthard brake events are recorded over the existing Hard BrakeReports, and once overwritten, the data is gone forever.ThomasBraun has attended the Detroit Diesel Training Center andcompleted a course of instruction on DDEC Reports/DataExtraction.
