Ok.. there is a code or codes in the computer causing this light to come on. We need ot pull codes to see what is gong.


Here is the procedure from alldata.



Data Link Connector

  1. Turn ignition switch to ON position.
  2. Disconnect short pin from DLC1, see Fig. 28.
  3. Using diagnostic check wiring tool No. 09843-18020 or equivalent, connect terminals Tc and E1 of DLC1 and DLC2.
  4. Read code from ABS warning light on combination meter. If no code appears, inspect diagnostic circuit.
  5. After completing check, disconnect terminals Tc and E1 and turn off display. If more than one trouble code is stored, lowest number will appear first.

Expert:  Amedee replied 6 years ago.

Your E brake could be stuck or one of your calipers could be locked up making it feel like the brakes are on constantly.

Had that checked alright emergency brake not on an checked the calipers an thier working it possible it could have somthing to do with the traction control pump or traction contol system.
Expert:  Amedee replied 6 years ago.

It is possible.. but I have never seen it...


One of the tires needs to be locked up or is dragging. You can jack up one side of the vehicle at a time to see which one it is...if this is not it... then maybe one of the front tires are not moving freely because of the axles or the transmission is not letting it move.


The only other thing would be an engine performance issue...

tried that also jacked up the the car all for wheels. The back wheels would not turn freely when car was put in drive an also netural

THat is definitely a problem!


Lets pull the codes from the computer... I have a a feeling this will point us in the right direction.
