Message Format and Usage (J1939/21). Most messages defined by the J1939 standard are intended to be broadcast. This means that the data is transmitted on the network without a specific destination. This permits any device to use the data without requiring additional request messages.
J1939 provides 19 different diagnostic messages that can be used to monitor, test, and clear diagnostic information in devices on the network. The BridgeWay provides support for 2 diagnostic messages: DM1 and DM2. The diagnostic message DM1 provides a list of the Active Diagnostic Trouble Codes.

J1939 Documentation¶. Overview / What Is J1939¶. SAE J1939 defines a higher layer protocol on CAN. It implements a more sophisticated addressing scheme and extends the maximum packet size above 8 bytes.
Therefore, the "SAE J1939 Message" (DM1 message) will be sent every 1 second while this fault is active. SAE J1939-73 Issued FEB96. EXAMPLE 2—The following illustrates the message format for when a request of the DM6 is made and all test results indicate no trouble information.
The documents SAE J1939/1x describe its structure; Chapter 3 contains a general description. The Ashcroft KD41 is an ECU-type 1 pressure transducer and therefore does not include bus termination resistors. Figure 2 depicts the CAN message format when using SAE J1939.
The DM1 and DM2 messages may contain multiple DTCs which mean the message may be transmitted using the Transport Protocol (TP). Both the DM1 and DM2 messages are defined by the J1939-73 specification. DTC Definition: Suspect Parameter Number (SPN).
