CAN FD diagnosis device extended to J1939

The handheld device PCAN-Diag FD from Peak-System (Germany) is for diagnosing communication on a CAN (FD) network. Now, a separately-available add-in is provided to also analyze J1939 data traffic.

The SAE J1939 standard describes communication in utility vehicles via CAN. Using PGs (Parameter Groups) and SPs (Suspect Parameters), the standard defines messages and data for the transmission of diagnostic and control information. Decoding of multi-packet messages with payload data up to 1785 byte as well as definition of up to 20 custom PGs are possible.

The CAN data traffic is interpreted according to the included J1939 database and is represented in a way that is understandable for the user, said the company. In addition, the add-in includes functions such as the decoding of multi-packet messages, address claiming, and the handling of diagnostic information. The J1939 add-in is activated with a device-bound license file which can also be purchased afterwards for a PCAN-Diag FD. Updates for the included J1939 database are included for a period of two years
