U0410 is set when the powertrain control module (PCM) receives invalid or implausible data from the fuel pump control module (FPCM) over the controller area network (CAN). The fault usually indicates a communication problem between the FPCM and other vehicle modules, which can affect fuel pump operation and engine performance.
An internal fault in the FPCM can cause it to send corrupted or out‑of‑range data to the network, triggering U0410.
Open, shorted, or corroded wires in the FPCM circuit can corrupt the data stream, resulting in invalid data being received.
Blown fuses, failed relays, or poor ground connections can disrupt the module’s operation, causing it to output invalid data.
Other modules or network wiring faults can introduce noise or errors, making previously valid FPCM data appear invalid.
Rarely, the receiving module’s software may misinterpret otherwise correct data; this is the least common cause.
No. The code almost always points to the fuel pump control module, its wiring, or power/ground issues. Replacing the PCM is rarely needed and is usually an unnecessary repair.
The fuel pump rarely directly causes this code; the problem is usually the control module that drives the pump. A failed pump may cause the module to report invalid data, but the module should be investigated first.
If the engine runs normally and there are no stalling or no‑start symptoms, you may drive a short distance to a repair facility. Persistent stalling or hard starting indicates you should stop and have the vehicle towed.
If a blown fuse is the root cause of the power loss to the FPCM, replacing it may resolve the issue, but the underlying reason for the fuse blowing (short circuit, overload) should still be investigated.
