Nissan Repair: nissan pathfinder, nissan pathfinder, brake fluid

Question
4WD,ESP and ABS have all  stopped working at same time.Any ideas? Thank you.

Answer
Ben,

If they have all stopped working I would check the fuses and relays for them.  ESP and ABS usually mean that the brake fluid needs to be changed.  But, the 4WD is out of the normal.  I assume that ignition switch is returning to the run position?  Wiggle the ignition switch to be sure you have it is full run mode.  There is an ignition run signal that allows all of these work after the engine starts.
