ABS, traction control and 4wd lights come on, brakes dragging? 2008 Jeep Patriot

When I start my car my abs traction control and 4wd light comes on the 4wd light flashes and when I start to drive the brakes will lock on slitly and off and on then 4wd will go solid and that puts it into front wheel drive ?? And it's when off for a bit then I filled my car up at a different fuel station and light came back on. Could it be the fuel ??
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
Hello – mostly likely, a malfunctioning wheel speed sensor or other ABS sensor is causing these symptoms. ABS, traction control and auto-engaging 4WD are integrated systems, and share sensors. A malfunction in one system can bleed over to the other systems. I would recommend an ABS system inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
Hello – mostly likely, a malfunctioning wheel speed sensor or other ABS sensor is causing these symptoms. ABS, traction control and auto-engaging 4WD are integrated systems, and share sensors. A malfunction in one system can bleed over to the other systems.
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 the 4WD warning light stays on constantly after you start the Jeep, you most likely will need to have the 4WD system itself at by a mechanic. Check the Owner`s Manual to see what recommendations it gives for this warning light. It may be safe to drive, but the 4WD system is probably disabled
Anti-lock braking system (ABS) malfunction

If the ABS and traction control lights both appear on your Jeep`s instrument panel, you should take your car to the repair shop as soon as possible.

Yes, this could be your issue. it aids in the speedometer and powertrain control module . if the power train control is not senseing any movement from that wheel it could keep it from engaging the four wheeel drive to avoid possibly burning out the transfer case.
Traction control and ABS often share the same control module and internal self-diagnostics system. This means that sometimes an issue in the ABS can trigger the traction control light to come on.
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 major difference between an ABS and a Traction Control system is that while ABS stops the wheel from spinning while braking, Traction Control stops the wheel from spinning while the vehicle is accelerating. A Traction Control System is also known as an Anti-Slip Regulation (ASR).
The “Service 4WD System” message indicates a problem with the 4WD system that should be properly diagnosed and repaired. When the ignition key is turned from OFF-RUN-START and is released back to the RUN position after the vehicle starts, the 4WD warning light should go on for 1 to 2 seconds and then go out.
ABS Light On After New Tires

If youre ABS light comes on after installing new tires, it`s likely that one or more of these sensors were accidentally damaged or bumped during installation. In which case, i tmay be best to have your vehicle inspected to ensure your wheel speed sensors are still intact.

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.
The traction control system light should illuminate for 1 to 2 seconds and then go out as the vehicle starts and begins to run. If the light stays on, it either means that the system is deactivated, or there is a problem in the traction control system.
The short answer is yes, low tire pressure can cause your ABS light to come on. The ABS (anti-lock-braking) system is responsible for maintaining contact with the road when braking. This suggests that you may have low tire pressure in one of your tires.

ABS, traction control and 4wd lights come on, brakes dragging? 2008 Jeep Patriot
ANSWER : Hello – mostly likely, a malfunctioning wheel speed sensor or other ABS sensor is causing these symptoms. ABS, traction control and auto-engaging 4WD are integrated systems, and share sensors. A malfunction in one system can bleed over to the other systems. I would recommend an ABS system inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

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.

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.

on starting engine light & throttle control and traction control light comes on and car idols hard no codes when scanned
ANSWER : Hello, and thank you for writing in. Unfortunately the first technician is correct in that this can be cause by a wide variety of issues. Considering that it is intermittent, we can assume that there is either an electrical issue (sensor or bad connection), or that there is a particular part which is dirty or failing. There are a couple of ways you can approach this. One being that you attempt to clean, repair, and replace the many number of components that can cause this. A second being that you attempt to replicate the issue by unplugging sensors and trying various tests to try and narrow down what system is being effected. When dealing with a misfiring situation, you need to look into the air intake, ignition (spark), and the fuel systems first. One last consideration is to have the vehicle scanned by another type of code reader. They vary in brand, manufacture compatibility, and software. For more diagnostic help, contact our service department to schedule an appointment, or to obtain a quote once the issue is diagnosed.

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, 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.

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.
