This information applies to the 2006 Buick Rainier, Chevrolet TrailBlazer, TrailBlazer EXT, TrailBlazer SS, GMC Envoy, Envoy XL, Envoy Denali and Saab 97x .
The Service Stability light is on and DTC C0455 is stored. When the Tech 2 is used, it lacks diagnostics capabilities. This is due to the software within the EBCM/VSES module that allows the Tech 2 to display data.
To obtain additional diagnostic data for the Steering Wheel Position Sensor, reprogram the EBCM/VSES with an updated calibration using TIS 2 WEB. Select the calibration titled "New software with diagnostic enhancements for DTC C0455 and changes that eliminate the need to replace the EBCM when the Yaw Rate sensor is replaced."
Once the EBCM/VSES has been reprogrammed with the new calibration, the Tech 2 will now be able to access addition stability data related to the C0455 DTC 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.
TIP:Â To access this additional data in the Tech 2, "build" the vehicle as a 2007 model year in the Tech 2.
If the vehicle is "built" as a 2006 model year, the additional Tech 2 data will not be available. Use the Tech 2 path below to obtain this additional Tech 2 data.
2007 / Light Duty Truck, MPV, Incomplete / Select Product Make (Chevrolet, GMC Buick or Saab) / Select Line (S or T) / Select Product Series (Rainier, Trailblazer, Envoy or 97x) / Chassis / Electronic Brake Control Module / Data Display / Select (ABS/TCS/VSES)
TIP:Â Install this calibration only when attempting to diagnosis a steering wheel position/C0455 concern, replacing a yaw rate sensor or when replacing and programming a new EBCM/VSES module.
TIP:Â This calibration offers no performance enhancement to the stability system. It only allows parameters previously missing in the Tech 2 to be viewed and aids in diagnostics, and the ability to recalibrate yaw rate on a 2006 MY vehicle.
