This document establishes methods for characterizing the robustness of vehicle electronic modules to certain electrical and temperature environmental stresses designed to address the deficiencies inherent in other commonly used validation methods. These methods included in this document are: a. Voltage-Temperature Design Margins; b. Voltage Interruptions and Transients; c. Voltage Dropouts and Dips; d. Current Draw Under a Number of Conditions; e. Switch Input Noise. These methods are best applied during the Development stage but can be used at all stages (e.g. Pre-Qualificaiton, Qualification or Conformity).
