03 Yukon xl Denali traction active message on accelration

Asked by Mar 24, 2017 at 01:50 PM about the 2003 GMC Yukon XL Denali 4WD

Question type: Maintenance & Repair

I have a "traction active" message come up while trying to accelerate. I turn
off traction control to drive vehicle. I have checked with a live scanner an all
wheel speed sensors show a default of 3 mph when stationary. Upon
accelerating 3 of the sensors "come alive" immediately. The left front wheel
"comes alive" at 12 mph, which is triggering the traction active message. I
replaced the wheel bearing/speed sensor assembly with new, but problem
still exists. What could be causing this?

When you accelerate, are any of the wheel spinning?

no this is on dry pavement

Do you have mixed sized tires?

Like on my car when I turn on the traction control, a tire light comes on to indicate that it is on. Would this be the case? And you do not need it on driving on dry pavement.

they are all new Michelin same size tires. This Denali has traction control on as default mode, and should be running in the "dark Indicator", which is normally on. When the light is on (tire with the bar across it) is traction control "OFF", and not the normal driving condition. This speed sensor also drops off to default mode (3mph), and sets off the Anti-Lock brake system when slowing below 12 mph. (like sensing a wheel lock up). At speeds above 12 mph, the Left Front sensor is running equal to all three other sensors. It is only the L/F sensor that is doing this. I have cleaned the connector, replaced the speed sensor then the wheel bearing hub/speed sensor assembly, and the problem still exists.

When the "traction active" indication comes on, it reduces the engine power to idle because it thinks there is wheel slippage, because the other 3 are spinning up and the L/F is still at the default (3mph). Once above 12mph, everything works normal until slowing below 12 mph again.

Ok did some digging, this is a quote... "To fix the problem, remove the front wheel speed sensors and clean any rust buildup from the sensor mounting area on the hub. Rust will hold the sensor away from the reluctor wheel and will diminish the signal." So check that distance to the reluctor wheel.

The air gap will cause the sensor to drop signal sooner than the rest and mimic a stopped or slipping wheel.

This event continued with the NEW bearing/hub/speed sensor assembly.

I know, but it sounds like it has to do with the air gap.

I see what you say, all one assembly so the reluctor is built in with the speed sensor mounted on the side. I would say it is a faulty speed sensor. I would change the hub bearing assembly out, have it warrantied. Between the sensor and the reluctor there is too wide of gap for the signal.
