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 ,
If battery light is on then, alternator
is bad or alternator belt is loose or broken...this will cause the
abs light to come on as there is not enough voltage to abs sensor...
