2005 Infiniti QX56 Question: check engine light came on while driving
Code P1000 indicates that the computer detects that all the "readiness" tests have not been met. This could be because the thermostat is failing and the engine's not fully warming up. I don't know why the light would come on for that code unless it was a persistent problem. I'd check that the engine comes up quickly to full running temperature and stays up before I check anything else. There are other reasons for P1000 to appear so don't make assumptions. If the thermostat checks out OK then you may want to consult an Infiniti specialist.

What is the cause of brake indicator light and VDC Off light and Slip indicator light while I was driving on the freeway? I shut off the engine and turned it back on, lights came back on again.
