OBD-II (EN): Lost Communication with Fuel Pump Control Module
Code U0250 indicates a loss of communication between the vehicle's main controller and the fuel pump control module via the CAN bus. The cause may be damaged wiring, a corroded connector, a faulty module, or a communication network fault. Due to the complexity of CAN network diagnostics, a visit to a workshop with professional diagnostic tools is recommended.
Symptoms
Check Engine Light (MIL) illuminated; possible engine starting problems or stalling while driving; reduced engine power or limp mode; additional CAN network fault codes may appear; in extreme cases, the vehicle may not start.
Possible causes
• Damage or break in the CAN bus wiring harness leading to the fuel pump module • Corroded, loose, or damaged electrical connector of the fuel pump control module • Faulty or defective Fuel Pump Control Module (FPCM) • Blown fuse for the fuel pump control module power supply • Damaged CAN bus terminators (120 Ω resistors) • Electromagnetic interference or short circuit in the CAN network causing communication loss

The code alone is not enough. To find the cause, you need to read live data, check freeze frame conditions, and compare with vehicle behavior. Book a diagnostic session.
