The cable was damaged and it was manifested by the lack of connection with the engine controller of the Ford brand, supported by the J1850 PWM protocol. The path inside the laminate, from pin 2 B + to the overvoltage protection diodes, has been burnt. The arrow shows where the damage is inside the laminate. The repair consists in repairing the connection, I made such a connection with one wire from a thin wire in insulation. It works as it should now, the cable number 8PZ 010 603-161 costs just over PLN 1,200, so it was worth it.
