Because this is a communication code, the "broken" part is often just a wire or a connection. Common culprits include: Low Battery Voltage:
: Using a multimeter, check for continuity in the communication lines between the actuator plug and the ECM. High resistance or an open circuit often triggers this "U" (Network) code. Actuator Testing nissan u1025-00
Check the wiring harness leading to the ABS/VDC actuator (usually located under the hood near the brake master cylinder) for any obvious signs of fraying or disconnected plugs. The Bottom Line Because this is a communication code, the "broken"
