I am experiencing the following symptoms: 1. Alarm sets its self off, even while driving. 2. Cruise control is disabled if I turn on the headlights. 3. Turning on the headlights and pressing the brake pedal seems to simulate the key being in the ignition and in the ON position. For example I can turn on the headlights and press the brake pedal with the key in the OFF position, or not even in the key cylinder, the instrument panel lights up and the fuel pump turns on. If I have been driving with the headlights on and I come to a stop, I can hold the brake pedal, turn the key and remove it from the ignition cylinder, and the car will keep running until I turn off the headlights, or release the brake pedal.
So far I have tried replacing the illumination control module (headlight switch) and I am still having symptoms. I have the dealership repair manuals if you need to reference any specific pages or wiring diagrams. I'm not sure where to continue my diagnosis from here. I'm trying to see if there is something I can try to test before giving up and taking my car to the dealership. Any help is appreciated. Thanks!
have the same problem?
