Does J1939 Truck Cable only Support Cummins Heavy Truck?

No, the 9pin truck diagnostic cable is usually suitable for vehicles that support the J1939 protocol. Cummins is often mentioned in our product descriptions because it is very representative. Our 9pin truck cable is also suitable for other brands of vehicles. For example, Mack, Freightliner, Kenworth, Cummins, Weststar, Cat. and so on are applicable.

Second, our truck cable is not for heavy truck only. We often use the word "truck" in descriptions. It's because the word is more representative. It not means that only truck can work with the J1939 truck diagnostic cable. As long as it supports J1939 protocol and also uses 9pin round plug, it will work. For example:

Passenger and freight vehicles: bus, light truck, heavy truck, etc

Forestry machinery: logging machine, timber carrier, wood collector, etc

Mining vehicles: bulldozer, excavator, etc

Military vehicles: tanks, transport vehicles, etc

Agricultural vehicles: tractors, harvesters, etc

Construction field: Hydraulic mobile lift, crane, etc

Rescue machinery: ambulance, fire truck, etc

Others: ships, electric buses, power generation equipment and pump machinery, etc

So is J1939 protocol only applicable to 9pin truck cable? No, it isn't. J1939 is only a common diagnostic communication protocol for diesel vehicles. It has no direct equivalence to the 9pin truck diagnostic cable. Depending on the design, it can also choose other connector as medium. But 9pin circular plug has established peer relationship with J1939 protocol earlier. Truck also used J1939 protocol long ago. Because both of them are representative, so we use the word J1939 9pin truck diagnostic cable or truck cable.
