ESP& ABS indicator light is in

The computer has detected a condition that indicates a fault with the ABS/Traction system. Typically that's caused by a wheel sensor problem, but it can also be caused by a faulty connector, peripheral device or the computer.
The above is the shop or garage answear. How about telling us how to fix the problem , besides replacing the computer or wheel sensor? How do we check these things?
Sometimes can be as simple as a short circuit in the rear break lights or a faulty connection in the break lights.
You can start checking the break light system. Then the sensors and finally the computer.

Antilock Brakes

I'm sure the code indicates that your ABS sensor went out. It's located in the front wheel hub assembly, and to change it, you need to replace the entire front bearing/hub assembly. They are about $150 per. But it the truck is handling ok and you can deal with the light, it's not a big deal since it's just a sensor....

Traction light is part of the ABS brake system. I had to the same problem 2 years ago and my auto repair guy said it was my front hub bearing. I replaced both sides with new hub bearing (right & left wheel) and now I have to replace the left one again. The thing about 04 grand prix gt they have a wheel/hub bearing problems. GM never recalled for this problem

Hi...your problem might be coming from your front wheel bearing hubs. They are know to cause this problem as they wear out and eventually have to be replaced.

If I helped...please rate me...thanks!

First of all replace bad wheel bearing !!! This bad wheel bearing causes ASR light ON.

ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.

For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.



ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.

The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

Check bearing and joint/knuckle on every wheel and even on the drive shafts, if there is lack/knocking, that could cause abs and esp light, because sensor doesnt give right information and ecu only records sensor fault but doesnt say why the infromation is wrong.
They changed the sensor but didnt solve the cause!!!

Ok, there are sensors on your front wheel hubs. This could easily cause the abs light to turn on. The loud noise could easily be your wheel hub going bad. Easiest way to check, jack up the front of the truck, grab tire, shake back and forth and up and down. Same amout of play each way? You're wheel hub is bad.......

I agree that it is more then like the the hub bearing assembly that also houses the speed sensor I would first check that there is no damage to the wiring that goes to the hub bearing that could be easy repaired, or debri that has been caked in between the sensor & the hub, use an air preesure to clean it out. Hub bearings are very expensive, so try this first. Good luck

usually when your front wheel bearing is wrecked the abs will go off.

cant reset the abs light till you change the bearing and get a new sensor..... if the bearing is the problem.

jack the front end up and see if you can wiggle the tire and up and down and see if it seems to wiggle in the hub. if the tire wiggles in the hub (not the suspension, in the hub) your bearing is worn out and the sensor has gone off. the new sensor comes with the new bearing.

good luck and let me know if i helped

You can do it yourself just take your time:
To change front wheel bearing.
1. Jack car up support with jack stands
2. take tire off
3. take caliper and brakes off
4. take rotor off
5. unbolt axle shaft nut at bearing hub
6. use a 3 lb slug with a block of wood
7. place wood on axle shaft and knock it in
8. back side 3 10mm bolts unbolt
9. front side have to pry off bearing hub Assembly only beacuse has dirt in knuckle hole.
10. clean hub knuckle and reinstall.
Its really not that hard or you could have them done for $900 and up. (I have changed alot of wheel bearing assemblies )Whats your e-mail I can send you a diagram if you want.
