2001 olds alero dash warning lights are all on when the cars on

SOURCE: 2001 Olds Alero Wouldn't Start

I had a problem similar recently, just wouldn't stay on. Found out that there is a flaw with the sensors on those cars for the ignition "talking" to the computer's Passlock II thing. The car thinks it's getting stolen so it engages the anti-theft which turns off the fuel injection. You just have to reset the Passlock. Turn the key to the first On position where you have radio but no windows, leave it for 10 minutes until the little Security light turns off. Turn off the key then start it.
Don't know if it was your problem, but just so you know, the sensor part will eventually start failing with this car.

check your body control module

no reset button.have the car anti-lock brake system scanned.to check code.because when anti - lock brake light come on.it can be many things.like faulty wheel sensor.faulty relay or the anti - brake unit low on brake fluid or the abs unit faulty.

If the previous solution doesn't work, try this:

While the key is in "on" position and your security light is blinking, it is probably your "Passlock" security device acting up. Very common in these years for GM cars. To test if this is it, simply turn your key forward (to "on" position) until light stops blinking and eventually turns off (right around 10 minutes). Then, turn key back off, and then try to restart it. My Alero did this just a few months ago and I learned this trick as I was pricing out a new fuel pump. If this was your problem, I recommend taking it to a remote starter installer and have them by-pass the passlock system permanently. This should cost anywhere from $40-$100, but is much better than a new fuel pump and filter cost.
-note: I recommend not getting it by-passed until it happens a second time (which it may not), just don't forget the temporary fix!

It is a sign that you either have a bad wheel bearing or 1 off your speed censors on 1 of the tires is bad, I just had this problem with my olds alero, but it was a wheel bearing that needed replaced.
