Method and system for displaying PIDs based on a PID filter list

A display device, comprising:

• one or more processors;
• a non-transitory computer-readable medium;
• and
• program instructions stored on the non-transitory computer-readable medium and executable by the one or more processors to:
• operate a display device in a state with connectivity to a communication network, wherein a remote server is connected to the communication network;
• receive, via a communication link coupling the display device and a vehicle to be serviced, two or more vehicle data messages transmitted from one or more electronic control units within the vehicle to be serviced;
• send a request over the communication network to the remote server, the request comprising a vehicle identifier and at least one symptom identifier based on content of the two or more vehicle data messages;
• receive a response sent over the communication network from the remote server, the response comprising a diagnostic filter list corresponding to the vehicle and the at least one symptom identifier, wherein the diagnostic filter list comprises at least one index value into an ordered list of tests stored at the display device, and wherein the at least one index value includes a first index value corresponding to a first test;
• output a test card on a display interface at the display device, wherein the test card indicates a subset of tests based on the ordered list of tests and the at least one index value, wherein each test of the subset of tests is selectable from the test card, and wherein the subset of tests includes the first test;
• and
• transmit, in response to a selection of the first test from the test card, instructions to perform the first test on the vehicle.

A non-transitory computer readable medium having stored therein instructions executable by one or more processors to cause a computing system to perform functions comprising:

• operating a display device in a state with connectivity to a communication network, wherein a remote server is connected to the communication network;
• receiving, via a communication link coupling the computing system and a vehicle to be serviced, two or more vehicle data messages transmitted from one or more electronic control units within the vehicle to be serviced;
• sending a request over the communication network to the remote server, the request comprising a vehicle identifier and at least one symptom identifier based on content of the two or more vehicle data messages;
• receiving a response sent over the communication network from the remote server, the response comprising a diagnostic filter list corresponding to the vehicle and the at least one symptom identifier, wherein the diagnostic filter list comprises at least one index value into an ordered list of tests stored at the computing system, and wherein the at least one index value includes a first index value corresponding to a first test;
• outputting a test card on a display interface at the computing system, wherein the test card indicates a subset of tests based on the ordered list of tests and the at least one index value, wherein each test of the subset of tests is selectable from the test card, and wherein the subset of tests includes the first test;
• and
• transmitting, in response to a selection of the first test from the test card, instructions to perform the first test on the vehicle.
