Autosar DEM (Diagnostic Event Manager)

1. Diagnostic Event Handling: Manages diagnostic events generated by automotive ECUs during vehicle operation.

2. Event Storage and Reporting: Stores diagnostic events in memory and reports them to external diagnostic tools.

3. Event Classification: Classifies diagnostic events based on severity, priority, and other attributes for prioritization and filtering.

4. Fault Memory Management: Manages fault memory in ECUs, including storing, updating, and clearing diagnostic trouble codes (DTCs).

Before learning AUTOSAR DEM (Diagnostic Event Manager), it's beneficial to have the following skills:

1. Automotive Systems Knowledge: Understanding of automotive electronic systems, including ECUs, sensors, actuators, and vehicle communication networks.

2. Embedded Systems Development: Familiarity with embedded systems development principles, including software design, programming languages (e.g., C), and real-time operating systems (RTOS).

3. AUTOSAR Basics: Basic knowledge of the AUTOSAR standard, its architecture, methodology, and key concepts, such as software components, communication stacks, and RTE (Run-Time Environment).

4. Diagnostic Standards: Awareness of automotive diagnostic standards such as ISO 14229 (UDS) and ISO 15765 (Unified Diagnostic Services) for diagnostic communication and fault handling.

By learning AUTOSAR DEM (Diagnostic Event Manager), you gain the following skills:

1. Diagnostic Event Handling: Proficiency in managing and handling diagnostic events generated by automotive ECUs during vehicle operation.

2. Fault Memory Management: Skills in managing fault memory within ECUs, including storing, updating, and clearing diagnostic trouble codes (DTCs) according to automotive diagnostic standards.

3. Event Classification: Ability to classify diagnostic events based on severity, priority, and other attributes, enabling prioritization and filtering for diagnostic purposes.

4. Integration with AUTOSAR Architecture: Understanding of integrating DEM into the AUTOSAR software architecture, including communication with other AUTOSAR modules and components.
