Having problems with your 1997 Pontiac Grand Am ?
I have a 1997 4 door Grand Am and the ETS light says off, what does this mean?
If you are talking about the light coming on when you are driving in\015\012slippery conditions, this is normal. If you are talking about it\015\012staying on all the time, the ets is either turned off or you have\015\012another problem. Let�s take a moment and explain why the electronic\015\012traction control which is called Enhanced Traction System (ETS) warning\015\012light will turn on when the engine computer sees a problem. The ETS\015\012system monitors wheel speed via the Anti-lock Brake System (ABS). If\015\012the ETS system sees a wheel spinning due to snow, ice, rain etc., the\015\012ETS computer sends a request to the vehicle�s engine computer to reduce\015\012torque. The engine computer responds with a combination of strategies.\015\012In the engine computer�s bag of tricks to stop wheel spin it can\015\012perform any one or combination of the following; cut fuel off by\015\012trimming or turning off fuel injectors, ****** the spark timing or up\015\012shift the transmission. In the days of old we just let up on the gas\015\012pedal. Now the computer does it for you. If you have an engine running\015\012problem it is more of a problem than you realize. The engine computer\015\012is the high command center. The engine computer will work and respond\015\012to information from the other computers in the vehicle. But in the\015\012event there is a system or running problem that the engine computer is\015\012responsible for, �it will� lock out all of the other vehicle computers.\015\012If there is an engine running problem that causes the engine computer\015\012to store a code and turn on the �Check Engine� light guess what\015\012computer doesn't talk to the others? The engine computer. The ETS\015\012computer gets all put out when this occurs and turns its warning light\015\012on in protest. So, there you have it. If the check engine light is on\015\012the ETS warning light will come on as well and the ETS system will not\015\012operate until the engine computer problem is corrected.
Have the same car an had the same problem. Nothing was wrong with the computer. In fact the wires in the console had gottin pinched an were cut spliced them back together an it is back to normal now.
