The Detroit engine hours data fault-code sheet is a Detroit DD Series (EPA 2007-Current) troubleshooting document for engine-hours data that is not received or has stopped arriving. It reproduces the official fault identification, the monitored parameters or service notes printed on the document, and the recommended diagnostic actions a heavy-duty technician follows step by step.

Applicable truck models
Detroit DD Series engines (DD13, DD15 and DD16) from EPA 2007-Current, with equivalent coverage noted for Series 60 (DDEC VI) applications. Fault code SPN 247 / FMI 9 is diagnosed with a diesel diagnostic tool such as DDDL or DDRS. For factory procedures and the latest module software, see the Detroit Diesel official website.
Diagnostic steps and checks
This information note covers the MCM engine-hours reading that is not received or has stopped arriving. It explains that the Common Powertrain Controller digital outputs share SPNs with some Motor Control Module faults, that the diesel diagnostic tool distinguishes the two, and that the fault normally follows CPC or MCM reprogramming when the module clocks disagree. Clearing all fault codes after reprogramming resolves the condition and prevents the code from resetting on the next key cycle.
Who needs this Detroit engine hours data manual
This troubleshooting sheet suits Detroit-certified technicians and independent heavy-duty workshops that read SPN 247/FMI 9 on a scan tool and want the factory decision tree, pin references and component checks before replacing parts.
