The ECM does not receive a valid J1939 message from a multiplexed device for more than 1 second. The ECM detects an open or short circuit condition in the J1939 Data link harness. Action Taken When the Fault Code is Active: • The ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails.
Since for J1939 SPNs 611-615 use the standard SPN/FMI format, it allows the use of standard diagnostics tools, electronic dashboards, satellite systems and other advanced devices that scan Parameter Groups containing the SPN/FMI formats (for J1939) and devices that scan for PID 194.
Section II.F presents the requirements for standardization of OBD information and communications. Upon storage of a MIL-on DTC and, depending on the communication protocol used—ISO 15765-4 or SAE J1939—the pending DTC would either remain stored or be erased, respectively.

All specified SPNs are also currently listed in table form in J1939-DA. An SPN is a number specified by the SAE. The start position of the SPN within a PGN is specified in the PGN description (see chapter Example of a Global Parameter Group). The SPN itself is always interpreted from LSB (right) to MSB (left), except for alphanumeric data.
