Applying good engineering practices to software-intense automotive systems can save automakers millions of dollars in warrantee costs, lost customer loyalty and lawsuits. Carefully crafted development testing could expose non-robust software that fails intermittently when the customer activates the function. The chances are very good the service technician will replace the ECU when the customer brings the vehicle in for repair of the intermittent behavior. These electronic parts are sent to the supplier for analysis. Upwards of 60% of all ECUs analyzed are TNI (Trouble Not Identified) related. This paper elaborates on a method of developmental testing that provides these cost savings. This paper continues to build on concepts discussed in the SAE paper, “The Bus Crusher and The Armageddon Device Part I”. [1] The experiment of subjecting an ECU to several electrical disturbances is explained in detail.
