    Also,
    USBC0_CC1: 0V (using both ports)
    Remove all power. Meter in DIODE mode. Red meter, yes red to ground. Black meter probe to the point to test.

    Measure the USBC0_CC1 pin anywhere you can in DIODE mode. Post your measurement.

    We are checking if perhaps the ESD diode @ DZF666 is defective.

      Hello, sorry for the delay. My wife and I had an accident on a motorcycle.. seems like it's been a lot of rainy days for me lately.

      It tests .482V at CF413

      The (seemingly) equivalent CF513 tested .51V
