Additional Diagnostic Information for StabiliTrak Service/Indicator Light On, Service StabiliTrak Message Displayed, DTC C0455 Set

When performing diagnosis for StabiliTrak® Service light on and DTC C0455 set, the Tech 2® lacks diagnostics capabilities. This is due to the software within the EBCM/VSES module that allows the Tech 2® to display the data.

To obtain additional diagnostic data for the Steering Wheel Position Sensor, reprogram the EBCM/VSES with the latest service calibration available on TIS2WEB using SPS.

Once the EBCM/VSES has been reprogrammed with the new calibration, the Tech 2® will now be able to access additional stability data related to the DTC C0455 and Steering Wheel Position Sensor. This data will include Steering Wheel Position Degrees, Analog Steering Wheel Position Voltage, Digital SWPS Phase A and Digital SWPS Phase B. To access this additional data in the Tech 2®, build the vehicle as a 2007 model year in the Tech 2®. If the Tech 2® is built as a 2006 model year, the additional Tech 2® data will not be available.

Important: This calibration should only be installed when attempting to diagnose a steering wheel position/C0455 concern or when replacing and programming a new EBCM/VSES module. This calibration will offer no performance enhancement to the stability system. It only allows parameters previously missing in the Tech 2® to be viewed and aid in diagnostics.
