Stability control disabled - 2004 GMC Yukon

why would you want the stabilitrak disabled it a safety feature tied into your abs--brakes-- traction control --if disabled those and certain options may also be disabled like cruise control --remote start ---if your looking to temporarily to work on vehicle pull your abs fuse --

Electronic stability control

It means you have a problem with the electronic throttle control an with Stability control which is part of the electronic brake control module ,which means there are DTC'S - diagnostic trouble codes stored in the ( EBCM ) & in the PCM -powertrain control module . You should take to a ASE certified repair facility or the dealer !

Service Stability System Message The message center displays the service stability system message when any one of many VSES-disabling DTCs is set. The EBCM sends a serial data message to the IPC requesting this display.
It means there is a problem an till you get it fixed the stability control system is disabled ! ( EBCM ) electronic brake control module Has detected a problem an set a DTC - diagnostic trouble code in it's memory an had the message displayed !
Vehicle Stability Enhancement System (VSES)
The vehicle stability enhancement system (VSES) provides added stability during aggressive maneuvers. Yaw rate is the rate of rotation about the vehicle's vertical axis. The VSES is activated when the electronic brake control module (EBCM) determines that the desired yaw rate does not match the actual yaw rate as measured by the yaw rate sensor.
The desired yaw rate is calculated by the EBCM using, primarily, the following inputs.
?€¢
The position of the steering wheel

?€¢
The speed of the vehicle

?€¢
The lateral, or sideways acceleration of the vehicle

The difference between the desired yaw rate and the actual yaw rate is the yaw rate error, which is a measurement of oversteer or understeer. When a yaw rate error is detected, the EBCM attempts to correct the vehicle's yaw motion by applying brake pressure to one or more of the wheels. The amount of brake pressure which is applied varies, depending on the correction required. The engine torque may be reduced also, if it is necessary to slow the vehicle while maintaining stability.
VSES activations generally occur in turns during aggressive driving. When braking during VSES activation, the pedal may pulsate. The brake pedal pulsates at a higher frequency during VSES activation than during ABS activation.


It

you may not be avail to disable, actually let me re-frame that, when the light is on the system is disable, limp mode.
is hard to do with out a scanner, but if you have one, replace your brake switch, and reset the light. the brake switch controls the ASR/ BAS/ STABILITY CONTROL/ THE CRIUSE CONTROL. CHANGE IT WILL FIX YOUR CAR.

it's a suspension system that makes sure your car is designed to help keep your car in control in CONTROLLABLE, in a UN-controllable condition ( to a degree ) ie.. slipping on ice, wet roads, etc..

The stability system is software programmed into the ABS - antilock brake control module also the PCM - engine computer . service engine light DTC'S - diagnostic trouble codes stored . Your best bet , take it to a qualified repair shop or the dealer . You don't have the diagnostic equipment or knowledge to tackle this type of problem .

A speed sensor in the rear differential is bad, resulting in engagement of traction lock mode. Have the diff. serviced with friction modifier additive. Damage to traction lock friction plates can occur if not serviced soon (expensive)

Your vehicle is equipped with vehicle stability control, what the system does is prevent the car from going out of control due to a skid, it does this by applying the brakes at each wheel very quickly to straighten the car out in the event of a skid like on ice or a wet road, the system is part of the ABS (Anti-lock brake system), when the light comes on and stays on it means that something has failed in the system and the computer that controls it has disabled the system

Your stability control uses the ABs wheel speed Sensors and the steering collumn sensor to know "when you need more stability". It sounds as if the front wheel speed sensor is sending bad info due to:
A) corrosion under the sensor causing erratic readings
B) front wheel bearing failing causing erratic readings
C) column sensor failing causing erratic readings

The GM dealer is the only place I know to have THOSE components tested. You can change any of these sensors yourself once you know which one it is. The "service stability" indicator is on because one of the sensors is not giving correct data, and the default mode is to disable the system. 

Good luck and hope this helps,
