Could be a problem in the steering column
Could be a shorted bulb (both filaments touching) searching for ground
I'd check the sensor for the emergency brake. It's probably faulty.
Get the green arrow to stay on. Now get out of the car and walk around it, looking for the turn signal bulb that stays on. That bulb has a bad ground. I fixed mine (very) temporarily with aluminum foil, then later by running a new ground wire. I just wrapped stripped wire around the base of the bulb and ran it to a ground.

In those older cars, if one light goes out, they all go out. The newer cars have independent circuitry.
If the signal light fuse is blown all the signal lights front and rear would not work. If you have one signal light out I would first suspect a bad bulb or bad connection.
It could be a problem with the ABS system, but if it just comes on by itself for no apparent reason, it may be the ignition switch.
You neeed to repair what is causing the light to come on. Then remove the neg battery cable for 30 seconds.
Bad flasher unit or turn signal switch
These systems are called Traction Control or in your case Enhanced Traction System. It is either on or off. Yours is turned off, thus the off light.
The owner's manual says it's the oil level, but sometimes my oil light comes on even after I've done three oil changes in the past year.
It could be your courtesy light fuse. See my answer on horn blowing continously. It is really hard to explain what the problem is.
