KPIT Cummins Confidential - Version 1.0 Case : OBD II: Attribute Management System Business Context An efficient attribute management system detecting the PENDING/ CONFIRM/ PERMANENT fault sates is essential for fault management to be in compliance with OBD II regulations. KPIT was chosen as the development partner due to the engine domain knowledge and experience with OBD systems. Value Addition Document for gap analysis between OBD and EOBD Requirement management using model based executable specifications Bench testing with customer simulator Increased productivity and schedule adherence leading to faster time to market and reduced cost Challenges Understanding OBD requirement & monitoring document Faster learning curve required for the resources Requirement Study & specifications Model development & Autocode generation Bench test Customer handover for vehicle test 11

KPIT Cummins Confidential - Version 1.0 Case: OBD- Model Verification & System Test Plan Business Context OEM wanted to incorporate the OBD II executable models created by the service provider in the Engine management System ( EMS) developed by the Tier I. Tier I provided the task for first level model verification and development of system test plan to KPIT Cummins based on KPIT’s domain knowledge of OBD and experience with Model based development Value Addition Automation of test data porting, execution & report Model verification ( Model in Loop) Understanding the models and developing the system test plan Challenges Understanding the executable models without any requirement document which required immense domain knowledge OEM Service provider for OBD executable models Tier I Engine Management System KPIT 12

KPIT Cummins Confidential - Version 1.0 Case : Handler Development Project scope Handler Development Outline The purpose of this project was to study ISO and to gather project specific detailed requirements, design and develop a generic Emission related Diagnostic software Requirement Gathering & study ISO Diagnostics services were developed in Diagnostics Kernel Integration with the OBD II Emission related Diagnostic services Functional & Unit test Features:  Application independent Emission related Diagnostic software, which communicates on CAN bus  OBD II Handler uses Volcano driver to communicate on CAN network to transfer information from an ECU to an off-board Tester and vice-versa  The information transferred consists of emission related data used in performing ECU diagnostics Development Platform Motorola STAR12 controller. Volcano driver Inputs Received ISO Deliverables Code Test reports 13
