ABS light won’t go off
ABS light stays on.
Experienced mechanics share their insights in answering this question :
The ABS system monitors the wheel speed sensors. When one or more wheels seem to be off from where they should be the ABS system modulates the chosen wheels brakes in order to match the speed of the others. If any of the wheel speed sensors fail in any way, or the tone wheel on the axel or inside of the wheel bearing fail, the ABS light with illuminate. When illuminated the brake system will still work but the ABS system will be disabled which greatly increases the chance of locking up the wheels. A proper inspection of the brake system should be carried out by a technician to find out why exactly your ABS light stays on.

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.
The ABS warning light/anti-skid brake light will come on or start flashing when there is a malfunction with the ABS brakes. The ABS control module continuously performs diagnostic self-checks. If it finds a problem, it will shut down the system.
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.
If your ABS light comes on individually, you are safe to drive your car to your destination, as your normal brakes will still work. You will, of course, have to be more careful as your ABS will not respond in case of an emergency.
When your car`s ABS light comes on, it means there is a problem with your vehicle`s braking system. You need to address this issue; otherwise, it could make your car unsafe to drive. ABS is a type of braking system used in all cars produced since Sept.
If the light really is the ABS light, the first thing to try is turning the ignition key off and back on. It`s like rebooting your computer. Maybe whatever transient issue that confused the ABS controller has passed and all is well. If the condition repeats, you need to do some further poking and prodding.
The anti-lock function will stop working properly, which may increase the distance it takes to safely stop your vehicle. The rear tires will lock, which will increase vehicle swing on turns and may make your vehicle more difficult to control.
In short, changes in the base brake system characteristics (hardware) may impact ABS/TCS/ESP performance in any or all of these three areas.
Yes, in a somewhat indirect way. As we`ve mentioned, your car`s ABS light can be triggered by low brake fluid. Worn brake pads deplete your brake fluid. By doing this, they can trigger your car`s ABS light.
If the ABS system is not functioning properly, then your vehicle is likely to skid, hydroplane and lose traction under heavy braking conditions. The last time you want to find this out is when you need it most in tough conditions, which could lead to an accident on the road.
Fortunately, if the ABS warning light came on, and no other warning lights are present, the brakes will still work. Just like they would on a car without ABS. But the ABS will not function and will not prevent the wheels from locking up in an emergency or on a slippery road.
On a passive ABS sensor, measuring resistance across the signal and ground leads generally produces a reading of 800-2000 ohms. A steady reading within this range indicates a good sensor. If the resistance is constantly changing or increasing on the meter, the sensor is faulty.

An ABS light is an alert that lets a driver know when there is a problem with their anti-locking brake system. The light is located on the dash, and is usually colored yellow, orange, or red.
The ABS brake light doesn`t mean you have zero braking capability. Instead it means that your brakes are now on their own, and you are too. If conditions are bad, your brakes will perform like brakes did before ABS. Without regulation, your brakes may stick right when you need them the most.
In certain cases, depending on the model of vehicle, when the ABS module fails, the brake pedal may become unresponsive. This is an obvious problem, as an unresponsive brake pedal will not stop a vehicle, or will not be able to do so in an adequately safe manner. In most cases, this will happen slowly, over time.
Typically these sensors will fail as a result of clogging from metallic debris, brake dust or dirt due to exposure to the harsh elements.
You can expect an ABS sensor to last 30,000 to 50,000 miles. If the sensor does fail, you should receive an ABS warning light on the dash, and your anti-lock braking system will not engage when needed.
On all car models, the ESP G419 sensor unit is installed under the left seat.
The antilock braking system, or ABS, is a safety feature that became common on new vehicles starting in the 1980s and `90s. It was aimed at preventing the wheels from locking up and causing a skid when braking on slick roads, thereby providing shorter stopping distances and better steering control.
In order to operate, your ABS system needs electricity. This is controlled by the anti-lock fuses and relay. The first fuse (a 10 amp fuse) must be good in order for electricity to flow to the relay, and the relay must function to provide power to the second fuse (a 30 amp fuse).
The ABS module in most cars should be located on the driver`s side front corner of the engine compartment. The hard brake lines should be attached to the unit, which should help you locate your car`s module.
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car`s braking performance.
Find the fuse to the ABS system, pull it out and you have no more ABS. The only thing is that the ABS light will be on after that.

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.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.

Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist 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.

ABS light on, ESP light on,Traction OFF light on, engine light on, rides perfectly OBDI reads only Front Right Wheel Speed Sensor
ANSWER : If a faulty component is still in place, the fault codes will return almost immediately after clearing them. ABS, ESP, and traction control systems all rely on input from wheel speed sensors to determine as the name implies, the speed of each wheel. When a wheel, or wheels are spinning faster than others due to wheel slip or the vehicle is sliding, the ABS and ESP systems can reduce throttle input as well as apply braking to an individual wheel or all of them if needed. With a wheel speed sensor fault code stored, these systems cannot determine the rate that all 4 wheels are spinning and sets a fault. That is why the abs/esp light is on. The system should be scanned by a certified technician and the wheel speed sensor replaced if found to be the cause. The warning lights will stay on and these systems will not function as designed until the fault is corrected. These lights do not come on to indicate a need for routine service. Rather they only come on when a component in the system is at fault.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

Chrysler 300 2005 abs not working. Code c2116. Does this mean my abs pump is dead for sure? Or could it be abs sensors.
ANSWER : Hi there. Take a digital volt meter and check the voltage on the harness to the ABS control motor. There should be a battery voltage present. If the voltage is low, then there is a break in the wiring from the computer to the ABS control motor. If the voltage is normal, then the ABS control motor has a burned cell and the ABS controller assembly would need replaced. This will effect the ESP system as well and set off the lights. If you need further assistance with your ABS system not working, then seek out a professional, such as one from Your Mechanic, to help you.
