Modular wireless diagnostic test and information system

A computer readable storage medium for use in an automotive diagnosis computer system, comprising:

• a first executable module including instructions that enable the computer system to accept user input and to display information;
• a second executable module that enables wireless communication to a plurality of instrumentation modules, each instrumentation module coupled to a select position of the automobile engine and for obtaining a distinct set of data from the automobile engine, the second executable module including instructions that transmit directives to at least one of the instrumentation modules and that receives a distinct set of data from the instrumentation module in response to the transmitted directives;
• and
• a third executable module including instructions that generate the directives in response to the user input and which selects at least one instrumentation module to provide information in response to the directives.

A method for automotive diagnosis, the method comprising the steps of:

• providing a first wireless communication link to a first instrumentation module detachable coupled to a first position of the automobile engine;
• providing a second wireless communication link to a second instrumentation module detachable coupled to a second position of the automobile engine;
• retrieving a first set of data from the first instrumentation module;
• and
• obtaining a second set of data from the second instrumentation, the second set of data differing from the first set of data.
