No b+ @traction controller.
Emergency disconnect contractor isn't ever pulling in and it provides b+ through fuse 9 to the traction controller.
Access 2 and access 3 modules both have their green LEDs on.
Access 3 is coding 1,4,1,7
code 417 is on the "wrench" screen and the display says "please stand by".
I cleared the codes and 417 returns. The truck never completes a self test.
