I read in the manual that you get to take it to the dealer and they will clear this wonderful code that activates the wonderful light on the dash. the redneck in me advises the use of black electrical tape over the wonderful light . that is how i fixed mine . I got the same year grand prix
Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.
If you are talking about the light coming on when you are driving in
slippery conditions, this is normal. If you are talking about it
staying on all the time, the ets is either turned off or you have
another problem. Let�s take a moment and explain why the electronic
traction control which is called Enhanced Traction System (ETS) warning
light will turn on when the engine computer sees a problem. The ETS
system monitors wheel speed via the Anti-lock Brake System (ABS). If
the ETS system sees a wheel spinning due to snow, ice, rain etc., the
ETS computer sends a request to the vehicle�s engine computer to reduce
torque. The engine computer responds with a combination of strategies.
In the engine computer�s bag of tricks to stop wheel spin it can
perform any one or combination of the following; cut fuel off by
trimming or turning off fuel injectors, ****** the spark timing or up
shift the transmission. In the days of old we just let up on the gas
pedal. Now the computer does it for you. If you have an engine running
problem it is more of a problem than you realize. The engine computer
is the high command center. The engine computer will work and respond
to information from the other computers in the vehicle. But in the
event there is a system or running problem that the engine computer is
responsible for, �it will� lock out all of the other vehicle computers.
If there is an engine running problem that causes the engine computer
to store a code and turn on the �Check Engine� light guess what
computer doesn't talk to the others? The engine computer. The ETS
computer gets all put out when this occurs and turns its warning light
on in protest. So, there you have it. If the check engine light is on
the ETS warning light will come on as well and the ETS system will not
operate until the engine computer problem is corrected.
sounds like a bad speed sensor in a wheel, or possibly a tire mismatch (different size tires on car front to back or one odd one) Abs can be turned off and will work in normal non-abs mode by pulling the appropriate fuse...This may help 'till you get it figured out.
Its the abs sensor, if you encounter an ice patch or snow you won't even be able to stop because the pedal will will push back and make the rip grind noise. If you pull the ABS fuse out, you won't have ABS but you can stop and you won't have the grind noise and back pressure for now. Its safer to not have ABS when the sensor is faulty.
the button on the side of the shifter is not for overdrive. it is your ets (enhanced traction system). it helps keep your wheels from locking up when braking in the rain or snow. btw, when the light is OFF, the ets is active.
