Sounds like your alternator is not charging. Several reasons: Alternator belt is off or slipping, batter is going out, alternator is not producing power. Any one of these problems will you stranded very soon. You will have not power to fire the engine and it will die even while driving down the highway. Do you have an ampmeter on your dash or just a light? If you have an amp meter is will slowly creep downward as you drive, when it gets down to about 8 or 9 volts your car won't start the next time you get in it. If it goes below 8 it may stop running while you are driving. If you are near an autozone or pep boy store they can check it for free, but caution, you have very little run time left before battery dies completely.

1995 Nissan Sentra, The engine light and brake

You could have faulty altenator or short causing the battery to drain. The engine light usually comes on when anything electrical or sensor wise is faulty. Brake light will come on if, low brake fluid, e-brake handle is up.

Battery and brake indicator light stays on after start

When the lights are on check the battery voltage. Should be 13.0 to 14.5. If you unplug the connector on the alternator when the lights are on, do they go off?

I had the same problem which was diagnosed incorrectly 3 times
Could be one of 2 things you may want to check
Have a tech read your codes
Have the ABS Control Module checked by a technician. If that is ok then make sure they look at the altenator
In my case, I was getting voltage spikes that were shorting out system controls -the ABS Control Module and the battery, etc. Once they put in a new altenator, the problem was fixed.
