SPN 1716 FMI 9 is the Detroit DD-series diagnostic code for a missing j1939 erc1 message, and this reference sheet lists its meaning and the step-by-step check on the J1939 datalink. Use it to confirm the code before touching wiring or modules.

Document table of contents
- Fault header: SPN 1716 / FMI 9 — J1939 ERC1 message is missing
- Note on shared CPC/MCM SPNs and diagnostic-tool distinction
- Step 1 — check for related codes: CPC SPN 168 battery voltage
- Step 1 — check MCM SPN 625/FMI 9 and repair the CAN line
- Step 2 — CPC reprogramming check and ServiceLink module status
SPN 1716 FMI 9 troubleshooting steps
The sheet first has you rule out related codes: if Common Powertrain Controller (CPC/CPC4) SPN 168 battery-voltage faults are stored, or Motor Control Module (MCM/MCM2.1) SPN 625/FMI 9 is present, those are repaired first and the Controller Area Network (CAN) line is checked. If only the J1939 error remains, Step 2 asks whether the CPC was recently reprogrammed; if so its configuration is verified, otherwise ServiceLink (the diesel diagnostic tool) is connected to read which modules are configured and their communication status, then the module-communication procedure for the affected module is followed.
Applicable truck models
This procedure covers Detroit DD-series engines — DD13, DD15 and DD16 on the EPA 2007-current platform — and is cross-referenced to Series 60 DDEC VI applications that share the same SPN/FMI structure. Confirm the engine family and emissions calibration (EPA07, EPA10 or GHG14) before following any step. For engine serial-number and calibration confirmation, use the Detroit Diesel official support site.
Who needs the SPN 1716 FMI 9 manual
Fleet technicians, mobile diesel mechanics and Detroit-certified shops chasing a datalink or module-communication complaint use this sheet to confirm the code, separate a wiring fault from a lost message, and avoid replacing a good control module.
