This message is cyclically send every second from the keypad. The cyclic time is a protocol
standard and can’t be changed. If no error is active, the data bytes [0-7] of the message
contains 0x00.
Example 1: Undervoltage Error (0x7F260)
The FMI for the example contains the value 0x04. According to SAE J1939-73 the value 0x04
stands for: “voltage below normal”. The occurrence count is 0x01. If the error occurs for a
second time, the occurrence count will be incremented.
Example 2: Stuck Button Error (0x7F070); Button 4 Stuck
The Button Number is added to the general stuck button SPN 0x7F070. The result is SPN
0x7F074 for button 4 stuck. The FMI is 0x02, that means: “data erratic, intermittent or
incorrect”. The error occurs for the 5
th
time.
̶ Two or more active diagnostic trouble codes:
If two or more diagnostic trouble codes are active, the trouble codes will be send over the
transport protocol. The following table shows the messages:
The data transmission starts with a broadcast announce message send by the keypad to
signalize an upcoming transmission of DM1 (data byte 5-7 of TP.CM_BAM contains the PGN
of DM1). The message contains the byte count of DM1 (16-bit value) and a message count (8-
bit value). After the broadcast announce message, data transfer messages are send by the
keypad. The first data byte of TP.DT contains the message number, the following 7 byte are
payload.
