The role of J1939 to OBD2 cable in heavy vehicle maintenance and repair

In the maintenance of heavy vehicles, the J1939 to OBD2 cable also plays an important role. Through this cable, maintenance personnel can quickly read the vehicle's fault codes and real-time data, providing strong support for fault diagnosis and maintenance.

For example, when a vehicle malfunctions, maintenance personnel can use OBD2 diagnostic equipment to read the vehicle's fault code through the J1939 to OBD2 cable. These fault codes can indicate the specific location and nature of the fault, helping maintenance personnel quickly locate the problem and take corresponding repair measures.

At the same time, by reading real-time data of the vehicle, maintenance personnel can also understand the current status and operation of the vehicle. This helps them determine whether the fault has been completely repaired and whether the vehicle can resume normal operation.
