are ESC/Traction and Brake light issues related?
I was flagged down and told my brake lights were not working, however upon inspection we discovered that while driving, my driving lights are fully illuminated, but when pressure is applied to the brake pedal the lights turn off unless the brake pedal is FLOORED and then the lights come on. we replaced the brake pedal sensor and that fixed the problem for a day or so and then the issue continued. an extended issues in my car is dash lights for "service esc service traction" but has caused no changes in function of the car, and the lights come and go and varied intervals that make no
Experienced mechanics share their insights in answering this question :
This is an electrical issue and, as well, the issue involving the ESC system is probably electrical in nature, too. I would suggest downloading the diagnostic trouble codes that undoubtedly have been stored relative to the ESC malfunction to see if those codes implicate any part of the brake light circuit (e.g., there could be a common fuse which has an intermittent connection). If those codes are relevant, you will start with those codes but if not start with a simple trace of the brake light circuit to determine where and why that circuit is not completing when the brake light switch is confirmed closed. To perform the diagnostic, you must have the Factory Service Manual wiring diagram in hand, so it might be more efficient for you to simply request an electrical component/circuit diagnostic – brake light/ECS system and the responding certified mechanic will get this resolved for you.

When this warning indicator light comes on in the dashboard, this could be an indication of several issues such as faulty wheel speed sensors, a faulty steering angle sensor, a faulty rotational speed sensor or a problem with the steering rack.
The traction control system maximizes traction while accelerating on loose or slippery road surfaces. The reason you are seeing the warning light continuously is there is a fault somewhere in the complex sensor system that makes the system work by regulating the engine`s output and selectively applying braking.
ESC light indicates when the driver switches them off manually. It could`ve been done by mistake or by using the car in a way that requires the stability control system to stay off. In either case, switching on the ESC using the button provided in the vehicle can switch off the light indicator on the dashboard.
If the ESC light stays on, it means your vehicle is not under control. And if the ESC light stays on for an extended period of time, your ESC may be malfunctioning, or the system has been manually deactivated. A malfunctioning ESC will stop working until any issues are fixed.
Is It Safe to Drive When The ESC Light Is On? You can still drive even when the ESC light is illuminating, but you need to take precautions such as slowing down. Also, have all issues affecting the ESC addressed by a certified technician as soon as possible.
The electronic stability control (ESC) warning light can be caused by electrical issues such as a low car battery or a blown a fuse. If your car`s ESC warning light is on, see your mechanic as soon as possible to get the problem diagnosed and fixed.
Press the gas pedal 3 times in quick succession. Then, turn your engine on all the way and let it run for a minute. The TCS and ABS lights should reset and go away if there isn`t any underlying problem with your traction control system.
Electronic Stability Control Explained
It`s almost always located as close to the very center of the car as possible. If you were sitting in the driver`s seat, the yaw control sensor would be under your right elbow, somewhere between you and the passenger.
When you are in a situation where intervention from the ESC system is needed, the lights will illuminate on the dashboard. It indicates that your vehicle is slipping. There is nothing to worry about, and once you regain control, the light will turn off.
Another common symptom of a faulty ESC module is a no start, or no spark condition. The ESC module is one of the components that directly controls engine spark, so if it fails, it can leave the vehicle without spark. A vehicle without spark may still crank, but will not be able to start or run.
Cost to Service ESC
Depending on the vehicle, a replacement steering angle sensor can cost between $100 and $200 or more. On occasion, a software reset or update might fix a problem with your ESC. Labor rates can also vary by vehicle make and model, as well as your region.
If both the ABS and brake system light come on at the same time, your vehicle is no longer safe to drive. This means there is a serious problem with the braking system, and continuing to drive puts yourself and others at risk of a car crash.
THE TECHNOLOGY BEHIND IT
If they detect that the car isn`t going in the direction you intended it to go, this feature helps correct your car back on-route by adjusting your speed and selectively braking one or more wheels. Without ESC, as this image shows, you may depart the road or get into a crash.
Resetting Your ABS Dashboard Warning Light
Step One: Disconnect the positive cable from your car battery. Then, hold down the brake pedal to drain the vehicle`s electrical system. This will result in a reset of the car`s central computer. Plug the cable back in to restore power.
In some vehicles it is located under the hood and/or is a part of the ABS control module. Other vehicles may have the traction control module located in the interior or trunk areas.
The ESC system constantly evaluates the data from the wheel speed sensors, steering angle sensor, yaw rate, and lateral acceleration sensor and compares the driver`s input with the vehicle`s actual behavior.
Electronic Stability Programme (ESP) is a recognised safety technology fitted to all vehicles since 2014. The lifesaving technology works alongside ABS and TCS to aid the driver in critical driving scenarios such as emergency braking, to correct understeer and/or oversteer and prevent an accident.
If the ESC is left on, it may prevent the vehicle speed from increasing, and result in false diagnosis. Turning the ESC off does not affect ABS or brake system operation.
How long does the membership last? ESC Professional Membership and subspecialty association memberships follow a twelve month rolling basis.
Electronic Stability Control (ESC) is effectively an extension of ABS, though much more complex. It can have many names, including dynamic stability control, vehicle stability control and active stability control, but they all function in much the same way.
Electronic Stability Control (ESC)
ESC helps keep the car in control when the vehicle is trying to skid or slide (approaching a corner too fast). It does this by applying the brakes (ABS) to one or all of the wheels to keep the car pointed in the direction you want.
The ESC will take power from the battery, adjust it to suit the instruction (polarity, ferocity etc) before passing it to the motor, which in turn spins to generate forward motion with the model.
APD BLDC ESCs control the motor`s speed by changing the voltage on the outputs to the motor (called the phase voltage).

EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.

When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
ANSWER : I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.

Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
ANSWER : The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit. For more help with these electrical tests, contact our service department.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

I replaced the brake light switch. Gear lever unlocked because it had locked. Now the brakes feel hard.
ANSWER : Hi, thanks for writing in. You need to check the brake switch install adjustment. You may have the switch adjusted too tight and it is holding the the brake pedal partly down. This will cause the brake master cylinder to not release the brakes when you let off the pedal. Readjust the switch away from the pedal until you feel some free play again in the pedal. This should fix the problem. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.

I have no brake lights and third brake light I have checked all fuses and brake pedal switch and the switch is fine and I’m still
ANSWER : Hi there. Well, you’ve listed most of the usual suspects including the brake switch, fuses and tail light assembly. However, one item you might want to also check is the accessory electrical relay. In some cases, the relay that supplies power from the brake switch to the tail light assembly will cause the issues you are describing. I always recommend that home mechanics purchase a service and repair manual for their vehicle to have a schematic accessibly, so it might benefit you to purchase one online to locate this relay or feel free to have one of our mobile mechanic some to your location and complete a brake light inspection, so they can help trace this issue for you.
