Status is Present.
Bits 7:0 Occurrence Count = 00001001
Occurrence Count is 9.
Registers 12:11
= SPN/FMI: FF 01 F4 FF
Since these registers are also defined bitwise, we first convert the hex value to binary.
$FF 01 F4 FF = 1111 1111 0000 0001 1111 0100 111
1 1111

Bits 23:5 SPN = 0000 0001 1111 0100 111

= 4007
Bits 4:0 FMI = 1 1111

= 31
The SPN and FMI indicate the diagnostic trouble code. All of the trouble codes are listed in the
Diagnostic Trouble Code List in the EMCP Systems Operation Troubleshooting Testing and
Adjusting manual. From that manual, SPN 4007 FMI 31 indicates “Generator Control Not in
Automatic Warning”.
After decoding the first log entry, this event then translates to:
#1 Generator Control Not in Automatic Warnin
