38.1 SPN 247/FMI 0
MCM engine hours data higher than expected – This fault usually occurs after reprogramming
the CPC or MCM. The internal clocks of the CPC or MCM do not match. After reprogramming
either module, all fault codes must be cleared.
NOTE:
The CPC digital outputs have the same SPN as some MCM faults. DDDL 7.0 makes the
distinction between the MCM and CPC when diagnosing a fault.
38.2 SPN 247/FMI 1
MCM engine hours data lower than expected – This fault usually occurs after reprogramming
the CPC or MCM. The internal clocks of the CPC or MCM do not match. After reprogramming
either module, all fault codes must be cleared.
NOTE:
The CPC digital outputs have the same SPN as some MCM faults. DDDL 7.0 makes the
distinction between the MCM and CPC when diagnosing a fault.
38.3 SPN 247/FMI 9
MCM engine hours data not received or stopped arriving – This fault usually occurs after
reprogramming the CPC or MCM. The internal clocks of the CPC or MCM do not match. After
reprogramming either module, all fault codes must be cleared.
NOTE:
The CPC digital outputs have the same SPN as some MCM faults. DDDL 7.0 makes the
distinction between the MCM and CPC when diagnosing a fault.
