Does anyone know why my Noritsu 3202 Pro cable burned out?

wiring overheating

The first and simplest reason that comes to my mind - it's contact oxidation and impendance increase as a result.

J/P413 is for the pressure change and lane select right sensors which run off +5V.
Either the plug on the sensor has got pulled off the sensor circuit board and is shorting to ground, Or there is damage to the cable somewhere, maybe the cable is trapped under a screw etc and is grounded.

Could it be an engine that overheated?

J/P413 es para los sensores de cambio de presión y selección de carril que funcionan con +5V.
O bien el enchufe del sensor se ha desprendido de la placa de circuito del sensor y está en cortocircuito a tierra, o hay daños en el cable en algún sitio, quizá el cable esté atrapado bajo un tornillo, etc., y esté conectado a tierra.

Now, how can I measure the voltage of each motor and sensor so that when I replace the cables and the circuit board, this doesn't happen again?

No, J/P413 only goes to the sensors, it doesn't connect to any motors.

Do a resistance check on the cable to make sure the +5V wires are not shorting out to ground.

I think some sensor caused the cable burning or the short circuit

Haz una comprobación de resistencia en el cable para asegurarte de que los cables de +5V no están haciendo cortocircuito a tierra.

How do I do that, I mean, I’m referring to which pin or which wire I check for that

On Plugs P288 and P413 Pins 2, 3, 5 and 6 should not be connected to GND
Only pins 1 & 4 should connect to GND
