Re: ABS Dash Light on??
The abs system has picked up on a problem with the abs. the abs will not be functional till the problem is repaired. the abs cpu needs to be scanned for fault codes and it will tell the mechanic exactly which part of the system is having trouble. once fixed the light will go out. mike

mostly it is good practice to disconnect the battery when working on a transmission removal and that may have affected the CPU program in the ECM
try using a scan tool to reset the ECM
AS to not connecting properly to the ECM , maybe the mechanic is not aware of the procedure
a broken wire on the abs sensor unit will put the abs light on but not the others
Traction control is with the wheel sensors. A bad sensor, bad bearing, or bad wiring. ABS is also controlled by these. Code readers don't read ABS and Traction control. Get the vehicle on a scanner....
Trac control and ABS lights come on usually when one of your ABS wheel sensors is either bad and needs replacing or corroded and just may need cleaning. This happened to me. It was my front left abs sensor. they replaced it and al the lights went out and all good now. I also bought an OBDII that plugs into your car and the computer tells the OBDII whats wrong and what sensor it is. You also get the option to erase the codes and put out some or all the lights on your dash. Some times a glitch will light a light on the dash and resetting or erasing it with the OBDII corrects the problem. Hope this helps. God Bless :O)
These two lights work together. The traction control uses the ABS to work. You most likely have a bad wheel speed sensor. Have it scaned with a scan tool under the ABS. Replace which ever sensor it says is open.
There may be another module have you replaced it under passanger side dash or on the fire wall under the hood lots of cars have to be reset by machine one of the two could be your problem you have to remember most cars now are all electronic hope this helped
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.
Only wiht a scan tool can that light be reset. If the brakes looked good to the mechanic then the problem could be a wheel speed sensor, transmission speed sensor, or the ABS module itself. This things can be checked by a diagnostic scan tool.
