I tried to unplugged the positive on battery and put back on thingking that I will reset that way and also tried to step on accelerator 3 times within 5 seconds but still there. Any suggestions?

    On my wifes 05 Trailblazer you tune the key on and depress the gas pedal quickly three times. I dont know why but sometimes it takes a few tries.
