Anti Brakes light comes on and cruise control quit working at the same time.
The Anti Brake Light use to flicker every once in awhile and just last Friday it comes on and stays on. At the same time this happened the cruise control can not be engaged.
My car has 58000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello there, the ABS and cruise control systems work together and any fault with the ABS will disable the cruise control. The most likely causes of the ABS light is an issue with the control module, ABS sensor, or low brake fluid. If you need some assistance, feel free to contact a qualified technician who will be able to diagnose your ABS light and perform any repairs that are required.

The most likely causes of the ABS light is an issue with the control module, ABS sensor, or low brake fluid. If you need some assistance, feel free to contact a qualified technician who will be able to diagnose your ABS light and perform any repairs that are required.
A Blown Fuse
If your cruise control system is electronically controlled, it will have an associated fuse. If there`s an electrical problem, the fuse will fail in order to keep other wiring from getting damaged. Try replacing the fuse. If it solves the problem and the cruise control keeps working, that`s great!
Most of the time this is caused by a bad brake switch. If the switch is shorting out, then it will cause the computer to think that the brakes are being applied, which turns off the cruise control. If the switch is fine, then it may have a bad speed sensor or the cruise control switch itself is bad.
ABS sensor faults
If any of the ABS sensors are faulty (there is normally one on each wheel), the cruise control system will not activate.
Because the ABS and traction control often share the same module, a problem with one mechanism might be indicated by a light for both. If the brake system is malfunctioning, the traction control light might come on as a result. The light for your ABS might also come on if the brake fluid is low.
Since your car`s cruise control is part of an electrical system, it needs a fuse to function properly. A short circuit in this system can cause a fuse to blow, which means that the cruise control will suddenly stop working. Fortunately, replacing a blown fuse is a cheap and easy repair for any auto mechanic.
Common signs include speed surges and inability to maintain speed on cruise control, as well as general engine performance issues.
The speed sensor is the part of the system that determines how fast a car is traveling. Since cruise control requires a precise speed reading, cruise control will not work correctly if the speed sensor is impaired.
Note that a weak battery can randomly knock other features offline, too, including adaptive cruise control, blind spot monitoring, and many more.
A radar sensor is installed on the car`s front grille, which can sense how close or far away the vehicle in front is. By sensing this distance, the car will “adapt” its cruise control speed to maintain a safe distance from the vehicle ahead.
The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off.
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.
If the TCS and the ABS warning lights both come on, along with the red main brake warning light, you should not drive the car until the problem has been fixed. Your entire braking system is affected, and may not be able to stop your vehicle when you need it to. Have your vehicle towed to a repair shop.
The primary input of the TCS is the wheel speed sensor. These sensors continuously monitor the speed of each driven wheel and send the data to the ABS and Traction Control System ECU. When a slip is detected between the tire and the road, the TCS regulates brake pressure on the slipping wheel.
Cruise Control in Newer Cars with Drive-By-Wire Throttle
The ECM is responsible for controlling the throttle body to accelerate or decelerate. Once you set your preferred speed, the ECU grabs that and sorts it out with the ECM and just like that, your car drives at your preferred speed.
While placing your hand on the servo, have someone turn on the ignition and turn the cruise control switch to the On position. You should hear and feel the solenoids in the servo click. This lets you know the switch is working and that you have power to the servo.
The cruise control system will be reset to the speed you are travelling when you release the knob. For a quick reset, accelerate with the accelerator pedal to the desired speed, then press and release the “SET/COAST” button.
Vehicles equipped with ETCS will automatically disable cruise control if there`s a problem with the engine or transmission, so if a check engine light lights up after starting the engine, get the vehicle to a mechanic as soon as possible.
When your vehicle is unable to shift out of neutral or park, this is a clear indication that there is a serious problem somewhere in the transition system. A failing transmission position sensor may no longer send the right signals to the Powertrain Control Module, or PCM.
Transmission Range Sensor (TR)/ Transmission Position Sensor
The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
1. ABS Light is illuminated on the dashboard. Since the wheel speed sensor also monitors the anti-lock braking system on your car, it`s common for the ABS Light to illuminate when the sensor is worn out, disconnected, or has been struck by debris, which means you`ll have to replace the wheel speed sensor.
It controls these systems based on the data it gets from the numerous sensors inside your automobile. When a battery drains, it may send lower voltages of power which may or may not hurt your PCM. But it can definitely cause some problems that are related to your PCM due to it not receiving enough voltage.
Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.
An adaptive cruise control system can, yes, but a standard “dumb” cruise control system controls only the engine (and by extension the transmission), which would not affect the brakes.

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.
Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.
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.
Brake light does not work.
ANSWER : Use the power wire from the brake light switch to activate the rear brake lights. By having an alternate power supply, ;the brake lights have no control without a switch, so the module is on but not functioning for the brake lights on the rear of the car. If you need further assistance with your brake module, then seek out a professional, such as one from Your Mechanic, to help you.
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.
All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be. If you need more assistance with repairing your vehicle please keep in mind that our organization provides Mobile Mechanics who can help you diagnose and repair your vehicle, all at competitive rates.
