the brake light switch will work without the key in the ignition if you push on the brake pedal, its just the way its designed. if you were to test the switch with a test light one wire is always powered up and the second wire is only powered when the brake pedal is pushes to activate the switch. if you test both wires without pushing the pedal I think you will find you have power on both wires indicating the brake switch has shorted and is working all the time. replace the brake switch.
Sounds like a possible air pocket in the braking system. Do you know how the bleed the brakes? They may need to be bled. Also, if you've added brake fluid recently, and didn't put the cap back on, it could create a suction. Another note is to check the cap to the brake fluid reservoir. It's rare, but, it could be bad.
Hi, if you didnt fix it yet I'll tell you what could cause the dash lights to come on while pressing on the brake pedal, and that is checking the bulbs AND putting the wrong one in the wrong hole, IE putting the back-up bulb in a brake/parking light socket . The single lead on the center of the back-up bulb shorts the double contacts on the brake/park light socket so the electricity just flows through the one tip of the bulb connecting the two contacts in the socket since the park and dash lights are on the same circuit the dash lights will be energized, hope that makes sense as it happened to me with a 66 mustang. Good luck!!
nothing, It doesn't work like that, when your brake switch is mounted , correctly , your pedal has a bracket on it that pushes the switch plunger in so brake lights are off. when you push brake pedal in, to stop vehicle, the switch plunger (spring loaded) comes out to turn brake lights ON ! get it ? when you release pedal it pushes plunger in, to turn lights OFF !
Resetting the oil life monitoring system
1. Turn the ignition key to the on position. Do not start the engine.
For vehicles with push-button start, press and hold the START/STOP
button for two seconds without pressing the brake pedal. Do not attempt
to start the engine.
2. Press both the accelerator and brake pedals at the same time.
3. Keep both pedals fully pressed.
4. After three seconds, the Service: Oil reset in prog. message will be
5. After 25 seconds, the Service: Oil reset complete message will be
6. Release both the accelerator and brake pedals.
7. The Service: Oil reset complete message will no longer be
8. Rotate the key to the off position.
For vehicles with push-button start, press the START/STOP button to
turn the vehicle off completely.
You can check to see if your brake booster is airtight. Start your truck, let it run for a couple minutes then shut it off. Push your brake pedal down a few times it should get harder to push every time you push it. Also press pedal down while engine is running then stop the enginewith the pedal still pressed down. If the pedal doesn't move after being held for a second after the vehicle has been shut off, then your booster is airtight. If your truck passes these tests then thats probably not your problem. I hope that helps you out. Let me know how it goes.
if you turned the steering wheel after shutting off the engine and the steering wheel caught the lock and tried to turn back it would hold pressure against the ignition lock cylinder. if it happens again try pulling the steering wheel hard one way or the other and turn the key at the same time.
If the battery is bad and not holding a charge, every time you push on the brake's. The break lights come on and puts a load on the electrical system and if the voltage drops below 10.5 volts, the ECM will shut down fuel injector and ignition system. The other thing to is that the fuel pressure may be dropping due to the electric fuel pump not getting enough volts every time you put on the brakes. You cold always try keeping the jumper cables connected to make sure it's the voltage drop that is causing the engine to stall. Keep me posted, be glad to help you get your car running 1005 again soon.
I had the same issue. It turned out that the break pedal switch was broken. The engine start push button is connected to a second break pedal switch that senses when you push it. That switch is independent from your main break pedal switch that turns on the brake lights of the car.
