service stabilitrack is displayed on my 2006 chevy trailblazer

service stabilitrack is displayed on my 2006 chevy trailblazer what does this mean and what is controlled by this

The stabilitrak system is controlled by the abs module. Its job is to maintain vehicle stability in situations where you may normally lose control by activating the abs system and/or changing the valving in the shock absorbers. When the message is displayed there is a problem in the system, could be an issue with a sensor or wiring. There are a couple of common problems with the system that require reprogramming the engine control module and the abs module. This must be performed at the dealer. The only way to know exactly what the issue is would be to have the abs computer scanned for trouble codes. Here are copies of the service bulletins regarding reprogramming.

#07-08-49-006: Intermittent StabiliTrak Service/Indicator Light On, Service StabiliTrak Message Displayed, EBCM DTC C0244 Set (Reprogram Engine Control Module (ECM)) - (May 7, 2007)

Subject:Intermittent StabiliTrak® Service/Indicator Light On, Service StabiliTrak® Message Displayed, EBCM DTC C0244 Set (Reprogram Engine Control Module (ECM))

Models:2006 Chevrolet TrailBlazer SS
with 6.0L Engine (VIN H -- RPO LS2)

 

 


Condition

Some customers may comment on an intermittent StabiliTrak® light being illuminated or a Service StabiliTrak® message displayed. Upon investigation, the technician may find EBCM DTC C0244 set in history.

This condition may be induced during wide open throttle acceleration from a stop or when accelerating onto an express way during low ambient temperatures.

Cause

This condition may be caused by the ECM sending out an invalid torque request signal.

Correction

A new calibration has been released to correct this condition. Reprogram the ECM using SPS. This new service calibration is available on TIS2WEB.

Be sure to select the correct calibration part number with the description that states -- to prevent C0244 at low ambient temperatures.
