Incorrect Fail/Warn/Timing Late Response Issued by tool V3.1.24 #1276

Closed anthonyhbest closed 4 months ago

anthonyhbest commented 10 months ago

In part 1.5 'PGN 65260 VIN Verification', the test tool is incorrectly issuing a fail, a warning, and a timing: late response. The vehicle correctly responds to the test tool request for VIN and the test tool captures that response. There is a subsequent VIN request from another component on the truck and the test tool is capturing the second VIN response and issuing the fail messages.

Do not assume that multiple responses are from multiple devices. Check source address. 6.1.5.2.b should verify that the first response from each module. 6.1.5.3.b should verify that multiple responses from the same module are the same.
