Question

Nissan X-Trail with code U1000, what is this code?

Answer 1

Hi there,

This code means one of the control modules is not communicating with the ECM. This requires a very good scan tool to determine which one it is, then it has to be tested to see if the module is the issue or another problem with the wiring.
