The test result messages are explained below:
No Error Found:
You may still need to test cable integrity by wiggling to test for intermittent connections.
If the test results indicate "No Error Found" and the vehicle communication continues to fail after the self-test
adaptor is removed, verify that the communication problem is not vehicle related; contact the authorized
service provider if necessary.
Error Found:
When the test result in self-diagnosis STEP-A is "No Error Found" but the result of STEP-B is "Error Found",
then there is a high possibility that the 16-pin Main DLC cable (P/No: 150109 - 00050) is inoperative. Contact
the authorized service provider.
