She grabbed her oscilloscope and back-probed the high-speed CAN bus wires twisted together behind the dashboard. The波形 looked fine at first—clean 2.5-volt square waves. But as she watched, a tiny, nasty spike of noise appeared every 73 milliseconds.

Understanding and Fixing Nissan Code U1025-00 (CAN Communication Line)

It depends. On Nissan vehicles up to ~2012 (e.g., Altima L31, Frontier D40), used ABS modules often work without programming. On 2013+ models (e.g., Rogue T32, Altima L33), the module must be programmed with the correct VIN and vehicle configuration using Nissan Consult or J2534 pass-through device.

According to the manual, code U1025-00 indicated a problem with the car's fuel pump control module (FPCM). Specifically, it meant that the car's engine control module (ECM) had lost communication with the FPCM. This code was usually caused by a faulty FPCM, a wiring issue, or a software problem. nissan u1025-00

Ellie raised an eyebrow. "Personality?"

Because U1025-00 is a communication code rather than a mechanical failure code, the root cause lies within the electrical network connecting the ECM to the turbocharger's electronic actuator. 1. Faulty Turbocharger Electronic Actuator

Nissan dealerships have access to comprehensive Technical Service Bulletins that provide step-by-step, vehicle-specific repair procedures for known issues. For complex CAN-related faults, Nissan has developed a for their vehicles. This flowchart is designed to systematically troubleshoot and resolve any vehicle-level CAN issue, including U1000 codes, wiring problems, and gateway malfunctions.

“CAN Communication Circuit – ABS/TCS Control Module Signal Mismatch or Missing”

The U1025-00 error code is a type of Controller Area Network (CAN) bus communication fault code. It indicates a loss of communication between the vehicle's control modules, specifically between the Engine Control Module (ECM) and other control modules on the CAN bus. According to the manual, code U1025-00 indicated a

Because the U1025-00 code is a network communication error, a methodical diagnostic approach is crucial to avoid replacing parts unnecessarily. Follow these steps:

The CAN communication diagnostic technical service bulletin (NTB13-027D) applies to nearly all Nissan vehicles from 2005 to 2024, with exceptions only for the 2023-2024 Ariya, 2022-2024 Pathfinder (R53), 2021-2024 Rogue (T33), and 2020-2024 Sentra (B18).
