Question about 1992 Pontiac Sunbird

ABS Light On

I have just recently replaced my brakes on the front and rear. I was informed by the mechanic that performed the work that my right front wheel sensor was bad. I had replaced the sensor but find that my ABS light is still on. I had been informed by another mechanic to disconnect the battery for about 15 - 20 minutes which I did. I noticed that the light had come back on as soon as I began driving and had not gone out. Could you please tell me how I can fix this problem?

    I have done as suggested, but light is still on. Is there a way that I can check the code without a scanner or a way to clear the codes and reset the ABS computer.

The connections of the sensor is not correctly done get it fixed where you had it replaced , they may be not connected it properly or the new sensor may be defective on your car.........

    First though to get rid of your indication lights you could try
    disconnecting your battery to let your computer reset itself. Just be
    sure to let your van idle for about 10 mins afterwards to allow your
    computer to reset or "relearn" its idle. I hope some of this helps you
    and good luck with your problem.

ABS light and traction light and no cruise control


how on earth would the blind know what is wrong.?
scan it? yet?
btw, newer cars cut cruise feature for any signs of danger.
new laws...
the traction needs ABS to work ,so forget that and fix ABS.
ABS needs 2 things to work , brakes and ABS.

so if brakes are bad, then ABS will get upset.
after all, if it cant brake right, how can the puter save you?
if brakes are known to be ok (inspections work here)
but in this case it was BREACHED by you, with out reading the book first.
then scan the ABS. (omg? code for dead sensor?) nah, you caused it..
easy

ABS resets every key on. so...
my guess, if ABS was happy before your actions( you never said)
then you got air in to the system. and failed to follow the FSM instructions on bleeding brakes, in ABS car.

front caliper, did you block the hose with cap, so it didn't allow air to the modulator? oops... never just let them drip... or . max pain.
bleed it again, (using any or all 5 ways to do so, bleeding is skill thing) (many modulators can not just be simply bled)

now Ill quote the 2012 fSM for you , under brakes

Data: -----------------------------------------------------------------
ABS Brake Bleeding
STANDARD PROCEDURE - ABS BRAKE BLEEDING

ABS system bleeding requires conventional bleeding methods plus use of a scan tool. The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system.

Perform base brake bleeding, (Refer to Brakes - Standard Procedure)(Refer To List 1).

Connect scan tool to the Data Link Connector.

Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then ABS BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed.

Perform base brake bleeding a second time, (Refer to Brakes - Standard Procedure)(Refer To List 1).

Top off master cylinder fluid level and verify proper brake operation before moving vehicle.

Uncle put new brake pads on vehicle (he worked on front and back brakes) and now the speedometer doesn't work, the abs light is on, check engine light, and the break light is on. what could have happened ....


Check for disconnected ABS sensors. The front sensors in the front are located next to the axle shafts. The rear sensor is located on the rear differential housing itself on top, in the middle. The ABS is monitored by the computer for performance. The ABS kicks on when the vehicle comes from a certain speed to a dead stop, keeping the wheels from locking up. That could be the reason for the speedometer not working. Or it could be a bad speed sensor. Both can also trigger the check engine light because it is monitored by the computer. The brake light usually comes on due to low fluid level. It can trigger the light, but not be low enough to impact brake performance. I hope this helps.

ABS ligth on caravan 2003


Yes, The light should clear after fix the problem. Check the connection on the sensors. Theres 4, one at each wheel. If you have air in the lines the ABS light will come on. To bleed go left rear, right front, right rear, left front. Don't let the reservoir go dry. Brake fluid should be changed every 30,000 miles

My abs light stays on 1995 chevy G20 van and have to replace front brakes every 6 months but rear brakes show no wear and are atleast 3 yrs old. On slick pavement right front brake sometimes locks when...


I'd be checking the sensor (ABS) at that wheel, (right front) and adjusting rear brakes to proper clearance, as well as inspect them for proper operation with wheels off.

Very poor brake performance after changing rear shoes


It sounds like your self-adjusters are not assembled correctly allowing them to back off when braking.

Bleed right rear,left rear, right front, left front in that order to be sure of good bleed but the brake booster makes it easy to push pedal. Make sure of no leaks from master cylinder. Otherwise brake hoses being soft will also hurt baking quickly.
