ABS/brake lights on
The ABS and brake lights are on. I believe it's the ABS module. I've had both the front wheel HUB assemblies replaced.
Experienced mechanics share their insights in answering this question :
Typically when a vehicle has the ABS light appear on, the brake light will appear right along with it. When this happens, the next step would be to use a automotive scanner to communicate with the ABS module. This will allow it to read what is causing the light to come on. If you believe the ABS module to be the problem it is best to have a certified mechanic, such as one from YourMechanic, stop by and confirm this is the cause of your ABS light being on, as ABS modules can be costly to replace.

The Chevy Tahoe ABS light is a common sight often caused by malfunction of the Tahoe ABS pump and module. This problem will also cause the Chevy Avalanche ABS light to become illuminated due to the same ABS system type being used across models.
Four Reasons Your Anti-lock Brake System Light Can Come On
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.
When the warning light is on, it could mean that a sensor has gone bad or needs cleaning. It could mean that the module has gone bad. A steady warning light indicates a problem that may affect your safety. A blinking light is a warning that your safety may be endangered if you drive.
Firstly, you should check your brake fluid reservoir to ensure that the levels aren`t too low, as the ABS warning light can be activated if the levels of brake fluid have dropped. If this is clearly an issue, you can top the brake fluid up yourself, which should cause the ABS light to go off.
In these cars, the check engine light will turn on if the ABS system is defective. It is often beneficial to learn about your car`s ABS light, check engine light, and other warning lights. Any time these lights turn on, you should address the associated problem right away.
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.
Wheel speed sensors are often called ABS sensors. You`ll find them mounted on the axles of all ABS equipped vehicles. Look for this sensor on your wheel hubs, near the brake rotors. You`ll find the rear wheel speed sensor mounted on the rear axle housing or wheel cylinder.
One reason your vehicle`s ABS light is on is because it may be sensing abnormally low levels of brake fluid. You`ll be able to notice if your brake fluid is low by the way your car brakes. The braking may seem soft or spongy. However, if the brake fluid is low, you`ll probably see more than just the ABS light come one.
The WABCO Electronic Control Unit (ECU) uses a pattern of light flashes called a blink code to identify specific problems, or faults, in the ABS. The warning lamp flashes a blink code for each fault that the ECU stores in its memory, enabling a technician to repair faults and erase them from ECU memory.
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. Your car likely has sensors in those tanks in order to detect when fluids are low, which could be dangerous.
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.
When your Chevrolet ABS light stays on while driving, it could mean that the anti-lock brake system (ABS) is malfunctioning. A fault code gets stored in the ABS. Your vehicle may require a longer distance to stop.

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.

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.

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.

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.

abs light on brake line broke have been replace I bleed brake line but brake pad still go to the floor now wheels lock up
ANSWER : Hello. If the brake pedal is going to the floor then that means that it is not building pressure. If the brake system has been fully bled and there is no air in it then most of the time it is a bad master cylinder or it can be caused by a bad ABS module. If the brake fluid was low and if air got into the system then the only way to properly bleed it is with a scan tool that would allow you to open and close the valves in the ABS unit. Air gets trapped in these easily if the brake fluid gets low. This can also explain why the brakes are locking up. I would usually use my scan tool to bleed the system out first before going any further. I would also scan the brake control module to see what it is reading as a fault. If there is no air in the system and if there is no prominent code then I would replace the master cylinder first. If you want to check out why your brakes are locking up, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

Brake sensor is to sensitive causing brakes to flicker while driving. 2005 Mercury Montego
ANSWER : Hi there – your brake light switch needs a minor adjustment. It is adjusted too "tight" or close to the brake pedal lever, or possibly has failed. Adjusting/replacing it will eliminate this flickering problem. I recommend a brake light isn’t working inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
