Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
I would like to know what I can do to shut off all these lights. I've taken it to AutoZone and Oreily's and they're diagnostics say the same error code "LOST COMMUNTICATION WITH ABS CONTROL MODULE." I wanted to know if I should clean or replace the ABS sensors first to see if that gets rid of the ABS light? If that doesn't work, would I just have to replace the module or the whole assembly minus the bracket it sits on?
If I replace that, would all the lights go away? Does the ABS even connect to all those other lights that are on?

Experienced mechanics share their insights in answering this question :
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.

If both the ABS and the 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 car`s braking system and continuing to drive puts yourself and others at risk.
An amber anti-lock brake system means that action is required. Roadside assistance: 0800 777 192. Anti-lock brake system fault. The vehicle can still be braked in the normal way, but the ABS and ESP may not function. Drive carefully to an authorised repairer to have the ABS system examined.
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.
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.
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.
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. Your ABS actually shares some important components with another system in your vehicle: your traction control system.
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.
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.

abs, traction control, E brake and check engine light comes on, code U0121 and U1120 show on scan tool what could be causing it?
ANSWER : Hi there. The only component that impacts the majority of these systems is a transmission speed sensor. In some cases, the sensor will slowly wear out, lighting individual warning lights when trouble codes are stored in the ECU. However, when all of them illuminate at the same time, it’s likely that the wiring harness was damaged somehow. I would first check the speed sensor and harness to make sure they are not causing your warning light issues first. If this is not the problem, I would recommend having all the OBD-II trouble codes downloaded by a professional mechanic as this might give you a better understanding of the root issue.
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.
The ABS light, emergency brake light and traction control light are on along with the unresponsive speedometer
ANSWER : Failure of one or more of the wheel speed sensors will cause all of these conditions to happen all at once. The wheel speed sensors and the DSC control unit will need to be checked and fault codes read out first. Then the wiring, connection, and wheel speed sensor of the affected circuit if a fault code is found. You may want to enlist the help of a mechanic, such as one from YourMechanic, who will have access to proper tools and service information to diagnose and correct these issues. If necessary, they will also be able to replace your wheel speed sensor(s).
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.
My check engine light and traction control lights are on and the cruise control light is flashing on and off.
ANSWER : Hi There,
What you are describing is common for a vehicle with traction control when it has been activated in a situation as you have described. The cruise control is also controlled in some cases by the traction control system and may be flashing as a need to have it reset due to the traction control being activated under those circumstances. The traction control system monitors the steering stability of the vehicle and engages when loss of traction has been detected. This is done by the use of electronic sensors at each of the four wheels that communicate with the Power Train Control Module (PCM) regarding steering performance and stability in adverse weather conditions. The traction control system works by reducing engine speed and determining which wheel to apply brake pressure to in order to prevent the vehicle from sliding. The anti-lock braking system and the traction control system work together to maintain the stability of the vehicle. The computer uses this information received from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle to determine how to direct the traction control system or the anti-lock braking system to best control the vehicle when needed. In some cases, the traction control system may simply need to be reprogrammed. I would recommend having a professional from YourMechanic come to your location to properly diagnose your traction control system.

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.
Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.
