Where are the abs. sensors located at?


The ABS sensors are located on the back side of each wheel in the area of the brakes. The sensors should not keep the car from running. A warning light should display on the dash, but should not keep the car from running.

ABS light on a 1999 jeep grand cherokee


Hi Amalia:
The ABS warning light comes on when there is a fault in the ABS System. When the light is on the ABS System is not working. A diagnostic scanner computer would be required to pull the trouble code and to diagnose the failed component would need to be repaired or replaced to get the light to go out.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I got a 04 jeep cherokee an my check engine just came on, I took it to auto zone and they told me something about the abs but I'm not realy shure what they ment so please can u guys help me more about...


hello juan. the ABS stands for antilock braking system. This is the system that automatically pumps the brakes for you. when the check engine light comes on for this issue, it is almost always a sensor, there is one for each tire. If your brakes are still pumping themselves on a hard stop, your ABS is still working. If they are not pumping themselves now, your ABS is not working. That said, the good news is you will still have brakes. you just have to pump them yourself. j.

Abs light stays on in my 97 jeep grand cherokee


The light means there is a problem with the abs pump or one of the sensors for the abs system. Your regular brakes will function normally but while the light is on you have no antilock braking. Abs systems can be fairly complicated, it may be best to take the truck to a reputable repair shop.

2004 Jeep Grand Cherokee The ABS light comes on and stays on. What does this mean?


You may have a faulty sensor, most cases a wheel speed sensor, the light is on warning you that you do not have abs basically your car will stop like an old 70's model car before abs. abs atands for anti lock brakes, it keeps your brakes from locking up under extreme braking.

Both the abs and brake light is on and stays on what could be wro


Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. Antilock systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails to pass the test one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. You or a technician will have to perform further testing to pinpoint cause and the proper repair.

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

Jeep Cherokee ABS light is on and now no brakes


Hi laustiin,
When the ABS system fails the brakes revert to standard brakes. The ABS module will not repair this for you.
The master cylinder is not likely to change anything either.
I am assuming that the pedal is full since you didn't say otherwise.
Your problem is most likely the brake booster. pump the brakes several times with the engine off to relieve any built up vacuum. While pressing down on the brake pedal start the engine. If the booster is working properly the pedal will move slightly down then press back against your foot. If it doesn't do this replace the booster.
If this doesn't help reply with more information and I will try to help you out.
Good Luck
