Jaguar yellow blinking light after updates

[Mark McLeod]

I'd think it'd be extremely unlikely that you'd be unlucky enough to end up with 3 out of 4 Jaguars broken out of the box. Although, 330 did get one Jaguar missing the PWM connection, but that was pretty obvious.

What are the symptoms of the broken ones?

If you're getting blinking yellow...
Unlike last year, this year the Jaguar's will blink unless code is explicitly setup to drive them. So PWM's 2 though 10 will give you a blinking yellow light with the code example you're using.
Since you have at least one working you can plug the working PWM and cable into each of the others as a test.
