J1939 code SPN 22. Below — how the fault is worded at the factory by Ford Trucks, Renault Trucks and ZF AS-Tronic, and what the second half of the code (FMI) means in the standard.

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 1 | Urea Level is too Low. FODP code (scan tool): P203F-00. |
| FMI 2 | Urea Quality Sensor Internal Electrical Fault – On / Short to Power. FODP code (scan tool): P206A-15. |
| FMI 3 | Urea Quality Sensor Internal Electrical Fault – On / Chassis Short Circuit. FODP code (scan tool): P206A-11. |
| FMI 4 | Urea Quality Sensor Internal Electrical Fault – On / Short to Power. FODP code (scan tool): P206D-00. |
| FMI 5 | Urea Quality Sensor Internal Electrical Fault – On / Chassis Short Circuit. FODP code (scan tool): P206C-00. |
| FMI 6 | Urea Quality Sensor Communication Failure. FODP code (scan tool): U02A2-01. |
| FMI 7 | Low Urea Quality. FODP code (scan tool): P207F-27. |
| FMI 9 | Air Cooling System Efficiency – Low. FODP code (scan tool): P026A-00. |
| FMI 5 | Clutch and lever angle position sensor, short to 0 V. Repair: Check the wiring between the control unit and the clutch actuator. Run the diagnostic check of the clutch actuator. If the fault persists, replace the control unit. |
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 5 | Short circuit to ground on ADVP/ADVP1 output (power supply for output shaft 1 speed sensor). |
Do not drive. Stop as soon as it’s safe to do so — don’t keep going.
The code is flagged critical: the manufacturer considers it unsafe to keep driving without checking.
This code alone cannot say what will fail next, so stop at the first safe opportunity and look at it on the spot.
That said, the manufacturer flags this code as critical — if in doubt, it is safer to stop and check on the spot.
