  3. History • 1980 On-board computers – self diagnostic capability – no uniformity • 1990s Introducing On-board networks • 1994-1996 On-Board Diagnostics, version II – mandated uniformity

  4. Automobile Repair Complaints • # 1 Automobile dealers - new and used • # 3 Auto repair shops • # 9 Automobile dealers - used only These three total 34,316 complaints for 1998 Better Business Bureau http://216.46.241.4/advertising/alerts/20000201.asp

  5. Auto Repair Fraud • Replacing brand new parts • Charging for repairs that were never done • Replacing more parts than necessary • Some stores implicated : • Sears, Midas, Montgomery Ward, K-Mart Auto Center, Goodyear* • * www.carinfo.com/repair2.html

  6. Fraud Cost! Estimated $5 billion annual cost** ** California Department of Consumer Affairs, October 27, 1999

  7. Objectives • TO CREATE A PRODUCT THAT WILL:1. be easy to install and operate 2. reduce anxiety, stress, and inconvenience due to auto repairs 3. increase the safety of drivers/ passengers 4. save owners money on some motor vehicle repairs. 5. reduce mistaken &/or fraudulent repairs 6. serve as the first major step in on-board system diagnostics 7. make a nice profit for the project team and investors

  12. Functional Specs • Plug, cable and protocol and processor-to-protocol converter must conform to SAE standards • User input - 4 buttons providing the modes : • Read DTCs and Ams -- Erase codes • Save codes -- Retrieve saved codes • Processor - 68HC11 • Storage memory - 4 MB flash card • LCD display- 40 characters per line and ten lines, backlight • Enclosure – measurements: 4” X 3” X 2” It must be rugged and secure as to prevent damage to the inside, outside and plug

  13. Dimensions

  14. Scope • Only 1995 and newer cars and light trucks • Supports OBD II protocol only • Not a mechanics substitute • Not a common sense substitute • Not supercede owners manual

  15. Milestones • Milestone 1(Functional Spec complete) All the hardware is defined and available within estimated price range to build PVDI • Milestone 2 (Database Completion) Database for the output message will be finished for reviewing of the lawyer and mechanic • Milestone 3(Prototype I) Individual software component completion • Milestone 4 (Prototype II) Hardware and software components put together

  16. Prototype I

  17. Contracts • All contracts include project plan, objectives, scope, functional components, functional specs, and schedule as part of contract • Contacts and deadlines • Specific remedies for violations • Spirit of cooperation and communication

  18. Risk Mitigation • Property damage & personal injury liabilities • Competition • Contractor/supplier delays • OBDIII changes • Patent

  19. Has this been done before? • The PVDI is portable • Gives descriptive messages • Gives priority numbers to codes • Is easy to use • Theirs is extremely complicated – useless for average consumer NO

  34. Deliverables • Preliminary project concept plan • Feasibility/ milestones/final presentation for customer • Product web site operational • Tables (AM and DTC) • Testing data • Prototype 1 (pc version) • Prototype 2 (box) • First units manufactured

  35. ODB 3 • Sophisticated sensors, monitoring telemetry and emissions • Fourth Amendment Issues • Uses transmitters to send data to satellites • Coupled with GPS = gov can find your car • Rat you out! “The specter of having Big Brother in every engine compartment and driving a vehicle that rats on itself anytime it pollutes is not one that would appeal to many motorists.” • http://www.me.umn.edu/~byronr/vw/obd3.txt Lary Carley
