I have a 2001 Pontiac Bonneville I replaced bad hubs what do I have to do to get trac off antilock and brake lights to go off

Did anyone put a scanner on it? Could be the fuse, a bad ground, the ABS pump, or the ABS module. some times wiring.

I Bearing hun does not work to fix, thentry then try the wie harness
start with driver sidefirst

the trac light is the traction control, the abs light means the antilock brake system is not functioning properly. the trac control is no issue. the abs will not cause the brakes to fail but they will lock instead of pulsing.

Pull the fuse or pull the plug off the unit. But I think you will loose your speedometer.

It is none of the speed sensors.The 1214 is system contact or coil open.The 1248 is for the ebcm turned light on.These 2 are for the electronic brake control module.The 1245 is for the low tire pressure.And the 1287 is for the steering wheel position sensor.What you should do first is clear the codes and road test the vehicle.When the light comes back on check and see what codes came back.The electronic brake control module is for the antilock brakes and the traction control.When you get the codes after driving the vehicle post back with them and I can help you with whatever codes you have.Good luck.

it is from a bad wheel speed sensor.The abs, traction control and other systems use the sensor.the various codes are for various system failures.The root cause is the sensor.

wheel speed sensors are in the hubs.

these vehicles have a history of problems with
the front hubs wearing out and causing a bad
reading from the front sensor. sensor comes
with the hub.

Something as simple as a different tire size can cause the abs to go nuts. I even had it where the two tires were the same size. But a different brand name. Each manufacture has their own tire sizing so not all tires a equal in size. Even though it says on the side of the tire that they are the same size.

Sometimes the cooper inside the insulation of the wires going to the sensors corrodes. Especially on the front units. It reads more ohms than normal but not open and is very intermittent. However moving the wires my make it work for a while. That's why replacing bearings seems to fix the problem but it comes back after a while.

You can test the speed sensors yourself...
Front sensor specs:
956 to 1240 ohms in 41 to 110 degree weather
at least 100mV AC (NOT DC!) volts when hub is spun by hand
Rear sensor specs:
950 to 1300 ohms in 41 to 110 degree weather
At least 100mV AC (NOT DC!) volts when hub is spun by hand

Here is some information from service bulletins that could be related to the problem. The traction control, antilock brakes, and tire inflation monitor all use wheel speed sensor input.

This first bulletin seems like it could be the problem because engine movement is involved:

GM Corporate Bulletin 00-06-04-049B
This Bulletin covers a problem that can cause multiple failures, one of which is an Antilock brake problem, and covers 2000-2003 Impala and Monte Carlo built prior to 2/03.
Check to make sure the wiring harness adjacent to the AC accumulator/dryer is not rubbing against the ac accumulator chaffing through the insulation of the wires in the harness.

GM front wheel speed sensor harness replacement - 2001-2003 Buick Century, Regal; 2001-2003 Chevrolet Impala, Monte Carlo; 2001-2002 Oldsmobile Intrigue; 2001-2004 Pontiac Grand Prix
This bulletin is about inspecting the harness going to the front wheel speed sensor for wear from contact with front suspension parts.
Repair harnesses/leads are available that can be spiced onto the main harness.

Hope helped.

You have a bad hub bearing. 100% garunteed. The light is on because the bearing is so bad it hit the sensor for the abs & traction control , breaking it. So you're gonna need a bearing, a sensor,probably new brake pads,any seals{probably one} & a shop that can do it. The bearing is pressed in & needs to be pressed out. Heating & beating is not a good idea.

try unpluging your battery cables for 10 to 15 mins.for the comp to reset.itself.
