What this code means

Component / fault: PTO.
Reported detail: PTO throttle signal out of calibration flash codes.
FMI 13 in the SAE J1939 / Caterpillar CDL convention means: Out of calibration — see the full FMI reference table.

On a Caterpillar display this code may appear as MID/CID 30 with FMI 13, or in the older PID/SID style. Wording of the reported detail follows the public Caterpillar fault-code listing cited below.

First checks (general, for this failure type)

The component is out of calibration. Run the calibration procedure in the service manual (often needs the dealer tool or a key / jumper sequence).

These are general electrical checks for FMI 13 faults, not a substitute for the model-specific test procedure. If the fault is active and the machine is derated or shut down, follow the service manual for your model and serial prefix.

Need the part?

If the checks point to a failed sensor, solenoid or harness part, send us the code (30 / FMI 13), the machine model and serial number — we quote genuine and OEM replacement parts for export.
