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

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?

NO•The PVDI is portable

•Gives descriptive messages

•Gives priority numbers to codes

•Is easy to use

•Theirs is extremely complicated – useless for average consumer

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

36


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.”
