When you have a check engine light come on, the traction control light and the cruise lights both come on as well. You need to have the codes checked with a scanner. There most likely isn't a problem with the traction control or cruise systems, the lights turn on because those systems work together with the engine management system or PCM. When there is an engine problem that sets a code that turns on the check engine light, it automatically disables the cruise control and traction control for safety reasons. Because the last thing you want is to have an issue with traction control and/or cruise control if your engine is having an issue, which is why they are disabled. The most common problem that turns on the check engine light is a loose, cross-threaded, or snug but not tight enough fuel filler cap. Subaru recommends three clicks of the cap to be considered tight. Also, any parts store can and will check and/or clear codes for free. I hope this info helps!
for check engine light to blinks is you have a serious misfire fix the misfire. traction control by ABS system when there is serious misfire and you keep on acc. then ABS module will turn on traction control light
HAVE VECHICLE CODE SCAN,SOUND LIKE YOU HAVE PROBLEMS WITH ABS BRAKES AND THE TRACTION CONTROL,SEEM LIKE YOUR AIR SHOCKS ELC HEIGHT SENSOR COULD BE BAD CAUSING AIR SHOCKS TO OVER EXTEND CAUSING CAR TO RAISE HIGH ON BACK END.WHICH COULD BE THE CAUSE OF ABS AND TRACTION LIGHT TO COME ON, TO FIX THIS PROBLEM HAVE CAR CODE SCAN AND YOU CAN FIND OUT WHAT CAUSING THE ABS AND TRAC LIGHT TO TURN ON.
that is traction control. most vehicles with traction control use a combination of brakes/throtle control and transmission upshifting to control traction. in other words, your car computer senses wheel spin and then overides you to make the car regain traction. most cars that feature traction control also have a button to turn traction control on and off manually.
this is a warning that there is a problem with the electronic traction control system, a part or circuit has failed, u will need to have the dealer test the system for a trouble code that will be stored in the control modules memory that will indicate were to look for the defective part, it will most likely be a wheel speed sensor, until the system light is out it is disabled.
