The Nissan fault code primarily indicates a communication failure with the Turbo Actuator

Q: Does replacing the ABS module require professional programming?

A: 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. nissan u1025-00

• Fix: Visually inspect the harness near the battery tray, the firewall, and the transmission connector.

• Use oscilloscope (if available) to inspect CAN differential waveform for noise/reflections.

If you are reading this, chances are you have just plugged a scanner into your Nissan and were greeted by the cryptic code: U1025-00. Fix: Visually inspect the harness near the battery

3. Wiring Harness Damage

Rodents (mice and rats) love the soy-based insulation used on modern wiring. They often chew through the wires that make up the CAN bus. Because these wires are twisted together, a bite mark can cause a "short" between the CAN High and CAN Low wires, killing communication.

In this post, we’ll break down what U1025-00 means, the symptoms to look for, and the most common fixes to get you back on the road.
