1.4 Eaton Hybrid Fault Message (DM1 with SA239)
This is based on Diagnostic Message 1 (DM1) for Active Diagnostic Trouble Codes. Please refer to J1939-73 for details. The dash panel needs to accurately report hybrid system fault information including amber “Check Hybrid” lamp, red “Stop Hybrid” lamp, and fault code (SPN, FMI, and SA). Source Address (SA), in this case, is 239.

1.4.5 Occurrence Count
Data Length: 7 bits
Resolution: 1 Occurrence count/bit
Data Range: 0 to 126 (a value of 127 is reserved for indicating not available)
1.5 Multiple Eaton Hybrid Fault (Transport Protocol)
When there are more than one hybrid fault, the transport protocol of SAE J1939/21 will have to be used to send the information because it requires more than 8 data bytes. Actually any time there is more than one fault, the services of the transport protocol will have to be used. Please refer to J1939-21 for details. When the dash detects HCM (SA239) send TP.CM and TP.DT that contain multiple DM1 messages, the dash panel needs to accurately report hybrid system fault information including amber “Check Hybrid” lamp, red “Stop Hybrid” lamp, and fault code (SPN, FMI, and SA).
CAN ID: 0x1CECFFEF (TP.CM)
Transmission repetition rate: Per the Parameter Group Number (PGN) to be transferred
Data length: 8 bytes
Byte: 1 Control byte = 32 (0x20), make sure it’s 32
2-3 Total message size, number of bytes
4 Total number of packets
