Yes. There is a very good possibility that your alternator is beginning to fail. The battery only starts the car and maintains nominal accessories. The alternator on the other hand actually provides the fire/spark for the engine after it has started o keep the engine running.
The light coming on and off is indicating the alternator is failing or falling below what is needed for the engine. When this occurs the system defaults to the battery, where it drains the battery. At higher speeds/RPM's the battery light is probably turning off - right?
A very easy way to check this is to start the vehicle, and with the engine running, remove the Negative (black) Cable going to the Battery. If the engine dies, it is the alternator and needs to be replaced immediately. Once an alternator fails, it will drain and kill the battery.

Sound's like your alternator is going out, if you have a voltmeter, with truck running check voltage at battery, that will be alternator voltage, should have no less then 13.5 volt's, if less bad alternator will need to be replace.also check belt tension pull on it if it feel's tie ok.

Sounds like your alternator is doing nothing-the car is running only off the battery. Have your charging system checked-does your battery light stay lit? If that bulb is burnt out, that may be why the charging system is not working. On some charging systems, that bulb is crucial for the alternator to work.
Engine off, a fully charged battery should measure 12.5 volts with a voltmeter. Engine idling, and the voltmeter at the same battery should be showing about 13.5 volts. This tells you the charging system is working.

How to read the engine codes without a Nissan CONSULT or scan tool. (Set ECM in Diagnostic Test Mode II) Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds....


there is a screw on side of the ECM. turn screw counter clockwise all the way and monitor dash board/check engine light on and count the number of flashes on dash board. when you are done turn the screw back into original spot.

The lights on my dash board flicker on and off then turn off.


I had the same problem some time ago, lights would go on and off, odometer appeared to stop counting at times rpm gauge would work and then not... power steering would off and on work and head lights would blink on and off when in driving light mode (off position).. The fix for me was I had to have the dash computer replaced (about $500). After doing this around 50k miles ago all the gremlins seem to have remained gone.. Hope this helps
