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.

check the outputs on the multi function switch (t/s switch) the brake lights and flashers all go threw this switch try to wiggle the flasher button if the lights start to work then the switch is bad to replace switch remove bottom cover by pedals if it has one bottom cover on steering colum has i beleave 4 screws that hold it on, the tilt colum lever unthreads and the cover will come off the upper colum just clips on you will have to remove the key tumbler to get it off . you need to disconnect the battery at this point and block the wheels. to get tumbler out put key in and turn to run postion there is a small silver button that pushes in with small screwdriver once its pushed in use the key to pull tumbler out the top cover will now come off you will probably have to tilt colum down and shift to 1 to get cover off there are 2 torx head screws that hold switch on plug new switch in and reconnect battery to test lights unhook battery again and reassemble please let me know how you make out

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?

Brake, ABS,STC,CHECK ENGINE LIGHTS ON.


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.
