Ford Trucks/Ecotorq writes fault numbers in its own format: the code in the table below is a Ford code (hexadecimal, zero-padded), not a J1939 SPN. It matches the standard only where the signal itself is standard, and usually matches the title of this page by digit alone.
| FMI 3 | Manifold Input Air Temperature Sensor Electrical – On / Off Power. FODP code (scan tool): P007D-00. |
| FMI 4 | Manifold Input Air Temperature Sensor Electrical – Chassis Short Circuit. FODP code (scan tool): P007C-00. |
| FMI 2 | Two Speed Axle Switch — Two Speed Axle Switch Error |
| FMI 19 | Incorrect data length of the CCVS CAN frame. Effect: Loss of communication with the modules, some functions are disabled. |
ZF AS-Tronic uses its own fault numbering: the number in the table below is an internal ZF code, not a J1939 SPN. It matches the title of this page by digit only and means something different.
| FMI 6 | Short circuit to positive supply on valve Y5 output (range selector valve). |
Safe to drive. Below — how much time you have and what happens if you keep going.
The gearbox or clutch has gone into limp mode: some gears may be unavailable and an automated box may stop shifting under load.
The main risk is being left on a climb with no gear and rolling back. Do not take a loaded truck into the hills; reaching level ground and a shop is fine.
