This case study demonstrates how the Synercon Technologies Forensic Link Adapter is superior at extracting critical digital crash data from Caterpillar powered heavy vehicles. I will show you how the Synercon Technologies Forensic Link Adapter was the only tool that could download the data from this bus crash.
This school bus crashing into the transit bus was for a test conducted by the University of Tulsa in conjunction with the Institute for Police Technology and Management. The testing took place as part of IPTM’s Special Problems conference on May 20th of 2015. The school bus had a 2001 Caterpillar 3126 diesel engine with a CKM serial number prefix. However, for this crash test, the engine was running at idle, and the school bus was pulled into the crash using a cable system. The impact was severe enough to compromise the electrical system of the school bus. This means we had to remove the engine control module to download the data. The Synercon Technologies Smart Sensor Simulator provides a fault free environment to power on the ECM and reduce the chance of overwriting existing diagnostic snapshot data.
Even though the CatET maintenance software recognized the QuickStop event corresponding to the crash test, it could not download the data. This is because CatET does not handle partial snapshot records. The forensic Link Adapter, however, can extract this valuable data. After plugging the forensic link adapter into the Smart Sensor Simulator, the screen prompts the user to acknowledge permission to download the data. After downloading data defined in the SAE J1939 and J1587 standards, the Forensic Link adapter recovers all the available snapshots, even the problematic Quick Stop occurrence from the crash test. Once the data is securely uploaded, decoded and rendered on the Synercon Technology Server, powerful visualization tools enable users to interact with the data like never before.
Since this example was from an instrumented crash test, the results are fully validated against reference instrumentation.
