Abs and park brake light came on same time

your vsa is vehicle stability assist that works with the abs system, verify brake calipers for proper functioning, sounds like breaks stick and cant return efficiently after breaking, vsa is a traction control light, if both lights remain on without flashing, those systems are disabled due to a problem, scan vehicle for possible abs sensor malfunction

Yes you should be able to disable the ABS but I cannot emphasize this enough.....DO NOT DRIVE THE CAR UNTIL FIXED.

ABS and the normal braking system is the same set of brakes. It is not 2 separate systems. You can disable ABS and that varies between manufacturers as to how to do that. It could be the simple press of a button marked ABS or entering a menu and disabling or it may require sophisticated dealer only equipment.
Your ABS is obviously faulty (or at least one of the sensors is faulty) as it should only operate when it detects a wheel locking up under braking and you should then feel the pulsing through your brake pedal as it disengages and re-engages rapidly to prevent locking up the wheel.
Find out how to disable the ABS and see if that stops the shaking. Do it somewhere safe, not the highway and do it at a slow speed. Best course is to get it looked at by a professional

check the calipers are not binding

look under the truck at the ****** and check the wiring to the sensors if good may be a bad sensor,also check the wiring and connections to the abs wheel sensors [ located from frame to the hub behind the rotors ] the abs also acts as speed sensor if problem was with an abs sensor at the[ hub] wheel usually set the brake system to normal power brakes [if u hit brakes hard will lock up or skid wheels] with the abs light coming on if the speed sensor at ****** malfunction can and usually causes shift problems

check for codes with scanner it most likely is the abs sensor on the rear differential housing that is bad easy fix

Abs light on means the ABS sytem has a fault.
You can determine what is wrong by counting the flashes (they say) and then put the data in on the web.

IE abs, windstar, failure, 3 flashes.

The brake light on is most likely picking up on uneven brake pressure, or a failing master cylinder/
You may not feel any difference yet, give it a little time, feel for a pedal fade at a light.

there is a problem with your abs sensor ....sounds like the sensor is applying the breaks for you when it shouldn't ....have a mech. look at it ...the e- brake issue could be causing a fault in the system ....all the symptoms may be the car.s computer,s way of telling you there is a problem "please bring me in "

There is an ABS sensor on each wheel. Check each one and make sure they are plugged in first. If they all are plugged in, then you may need to replace one or more of them. You can usually see if they are bad. Hope this helps.

one of tha abs and traction sensors has blown

Probably air in the ABS or bad ABS. don-ohio (:^)
