Traction control

[hotmetalram]

My traction control light comes on after I hit any kind of bump and stays on. I've noticed it happens in hotter conditions but not in below freezing temps. Had the steering and front end looked at with no visible problems. Brakes, tires and alignment good. Any suggestions to what might cause this light to stay on?

Wheel speed sensor is a possibility.

Have the system scanned and see what specific code it is. There are many specific codes that can come up and trigger that light. Otherwise you are just guessing. If it was a wheel speed sensor I would suspect you would have ABS and other brake related lights also. The traction control is activated and controlled by the ABS controller, and functions by applying brakes at certain wheels. So if one rear wheel is on ice and spinning, it will apply brakes to that wheel to slow it down and help transfer power to the other wheel. Both the antilock brakes and traction control activate based on input from the wheel speed sensors.
Any chance the truck is bouncing bad enough where it actually is triggering the traction control. Keep in mind that the traction control light will come on when the system is activated, for example if you start spinning the tires on snow the traction control light will come on. Doesn't mean there is something wrong any time the light comes on, just that it has activated.

Every shop tells me something different. Front end felt very loose. Most of the bushings were cracked, deteriorating and in bad shape. Then I started hearing popping. Ice and wet slick roads with weak suspension??? I've now had upper control arms, ball joints, sway bar link bushings, inner and outer tie rods replaced and alignment done. On my way home today the traction control light popped up. I have a traction control button on my console which lights up in different area. This light is the one with the swervy lines underneath. I was told this lights up if there was a problem?
