In the TEST.PD.PHY.ALL.3 test, the GRL-USB-PD-C2 / C2-EPR tester hardware checks that the DUT properly implements collision avoidance requirements.
According to the CTS, the GRL-USB-PD-C2 / C2-EPR tester hardware will send Continuous zeros after sending the BIST message. The DUT should not send GoodCRC.
As seen in the example below, the DUT is responding with GoodCRC and thus the test is considered as FAIL.
The following example can be seen if the test Passes.
