Can a car brake light work with the key off?
Any help much appreciated! Umm… some vehicles brakes lights work all times (eg. Toyota) some only work with ignition on (eg. Ford). What you’re saying doesn’t quite make sense. Most Japanese vehicles’ brake lights will keep working with the key off. Maybe it’s just a coincidence and your brake light switch is stuffed.
Why does the brake light work when the engine is off?
If engine running, the brake pedal is easier to apply (because of vacuum assistance) – another guess is your brake light switch needs adjusting so it doesn’t need as much pressure on the pedal to activate. payaya writes… I reckon you have a sticky relay.
Why do the brake lights not work on my Integra DC4?
Today when doing some maintenance on my integra dc4, I noticed that when I turn off the ignition and step on the brakes that the brake lights don’t work. Stepping on it multiple times it would sometimes turn on and other times it didn’t. However, when I start the car/drive it, the brake lights work fine.
What happens when you change the brake fluid?
If you have an inconsistent amount of brake fluid in the car braking system, you are bound to get unpredictable results. Due to this sudden change, the brake lights may turn ON or OFF when driving and may fail to shut OFF when the vehicle is in a parking lot.
Why does my car not start when the brake light is bad?
The car may also not start because, in automatic transmission vehicles, the car needs to detect that the brake pedal is pressed. If the brake light switch is bad, the Engine Control Unit (ECU) will think you are not pressing the brake pedal, therefore not allowing you to start the car.
Where is the brake light switch on a car?
When the brake pedal is pressed, it closes the switch, and the current flows through the wiring to the brake lights. This turns on the rear brake lights. The brake light switch can also be located on the master cylinder. Hydraulic pressure from the master cylinder brake light switch system can close the switch to turn on the brake lights.
Why does my car not start when I put the key in?
Putting the key in the ignition switch and starting the car feels like second nature. However, if your car has ignition switch problems, you may not be able to start the car at all. Ignition switch problems can also cause issues on the road, such as unexpected shutdowns or electrical problems.
Why does my car run when the ignition is turned off?
With the ignition turned off and the car continuing to run, simply remove the plug from the alternator (DO NOT TRY AND REMOVE THE BATTERY POWER WIRE FROM THE POWER STUD!) and the car should shut off if the alternator is creating the problem. If it does not stop running, your feedback problem is coming from something other that the alternator.
