## Abstract

A method for identifying each of a plurality of parameter identifiers in a motor vehicle having a diagnostic test port using a diagnostic test tool is disclosed wherein the method includes the steps of plugging the diagnostic test tool into the diagnostic test port of the motor vehicle, receiving identification information from one of the plurality of parameter identifiers, determining whether the identification information from the one of the plurality of parameter identifiers is valid, and storing the identification information in a tailored list to be used to address the one of the plurality of parameter identifiers to retrieve data collected thereby.

## Claims

### Claim 1

A method for identifying each of a plurality of parameter identifiers in a motor vehicle having a diagnostic test port using a diagnostic test tool, the method comprising the steps of:
plugging the diagnostic test tool into the diagnostic test port of the motor vehicle;
receiving identification information from one of the plurality of parameter identifiers;
determining whether the identification information from the one of the plurality of parameter identifiers is valid;
identifying an invalid response when the identification information is not valid; and
storing the identification information in a tailored list to be used to address the one of the plurality of parameter identifiers to retrieve data collected thereby.

### Claim 2 (depends on 1)

A method as set forth in claim 1 including the step of storing the identification information in the tailored list of each of the plurality of parameter identifiers when the step of receiving identification information is not established.

### Claim 3 (depends on 1)

A method as set forth in claim 1 including the step of receiving identification information from another of the plurality of parameter identifiers.

### Claim 4 (depends on 3)

A method as set forth in claim 3 including the step of displaying all of the plurality of parameter identifiers in the tailored list.

### Claim 5

A method for identifying each of a plurality of parameter identifiers in a motor vehicle having a diagnostic test port using a diagnostic test tool, the method comprising the steps of:
plugging the diagnostic test tool into a diagnostic test port of the motor vehicle;
receiving identification information from one of the plurality of parameter identifiers;
determining whether the identification information from the one of the plurality of parameter identifiers is valid;
identifying an invalid response when the identification information is not valid;
storing the identification information in a tailored list to be used to address the one of the plurality of parameter identifiers to retrieve data collected thereby;
receiving information from another of the plurality of parameter identifiers to determine whether the identification information received from another plurality of parameter identifiers is valid; and
displaying all of the plurality of parameter identifiers in the tailored list.

### Claim 6

A method for identifying each of a plurality of parameter identifiers in a motor vehicle having a diagnostic test port using a diagnostic test tool, the method comprising the steps of:
establishing a communication between the diagnostic test tool and the diagnostic test port of the motor vehicle;
receiving identification information from one of the plurality of parameter identifiers;
determining whether the identification information from one of the plurality of parameter identifiers is valid;
identifying an invalid response when the identification information is not valid; and
storing the identification information of the one of the plurality of parameter identifiers when the identification information is valid in a tailored list to be used to address one of the plurality of parameter identifiers to retrieve data collected thereby.
