If my alternator is going would that cause my battery light AND my ABS light to come on?? I understand the battery light but my ABS light??

Without a heat strip on the battery and a block heater, at that temperature the battery isn't going to be optimal at supplying power. Look for a draw on the battery when the engine is not running. It coud be a light in the glove box , trunk or under the hood causing it or your alternator may not be charging to it's fullest. If just one diode in the alternator is shorted you'll drain the battery over night. If one is open, the alternator has lost 1/3 of it's rated output. If your hrad lit switch is on the steering column, it's possible it will turn the head lites on when it gets cold..Happened to me.

Believe it or not. The alternator can cause these problems to manifest as well. Do you have good braking? If you seem to have good braking then I'd go to an Autozone and have them place a battery tester on your car. A low alternator output can cause problems in ABS systems.

Hey Lg,,
Have your battery/alternator checked at a battery/alternator shop... you may have a loose connection or one or the other is going bad..??

Alternator could be going out and can cause this problem...

There is a part on the engine called the "Alternator", the alternator is what charges up the battery and supplies the power to the cars electrical system when the engine is running, when the voltage output of the Alternator is to low it causes the Battery warning light in the dash display to come on (to alert you of a problem in the charging system), the low voltage from the alternator also is what is causing the ABS warning to come most likely. So at this point you will need some basic testing done to determine the cause of the low voltage, this can be the alternator is defective (most likely reason) or other things like wiring issues to the alternator.

check for voltage from the alternator, charge the battery ,, with a multi meter set to DC volts ,, check voltage, you should have a reading just a little over 12v dc, then start the car,, check again, you should get a reading between 13.5 volts to 14.5 volts , if you have that your alt is good,, if not Its not charging the battery as your driving, having a low battery makes the computer go crazy and it looks for anything wrong,, Ive had dash lights for everything light up ,

Traction light is on because the abs is on.Traction control needs to have the abs system fully functioning to work.Most common cause of abs light is a wheel speed sensor.As for your lights flickering the alternator may be going out or you have a poor ground connection.Would check battery cables first to make sure they are tight.

MAKE SURE YOUR CAR BATTERY AND ALTERNATOR IS IN GOOD OPERATION.HAVE THEM TESTED.I HAVE SEEN A CAR WITH ABS AND AMPS LIGHTS ON.THE ALTERNATOR WAS NOT PUTTING OUT ENOUGH VOLTS TO RUN THE ABS BRAKE SYSTEM. IF ALTERNATOR AND BATTERY IS GOOD.I WOULD REPLACE THE ABS RELAY FIRST.ITS GOES BAD CAUSE THE ABS BRAKES NOT TO WORK.IF ABS RELAY IS GOOD.THEN IT HAS TO BE ABS MODULE GOING BAD.IT HAS TO BE REPLACED.

sounds like a open diode in alternator,when brake and battery lights come disconnect green plug on alternator,if the lights go out you've found the problem,very common problem with subarus

yes it's most likely a alternator problem,usually the internal diode bridge breaks causing all lights you mentioned to come on,if this happens at a idle open the hood and remove green connector on alt.if lights go out you've found the problem
