2006 Chevrolet Suburban C2500, 6.0 USECTION Diagnostic Aids
  • The following scenario may cause this DTC to set when no actual malfunction exists:
    • The vehicle is driven in a straight line in reverse at a speed greater than 13 km/h (8 mph).
    • The transmission is shifted into NEUTRAL while the vehicle continues to coast backward.
    • A turning maneuver is performed after the above conditions are met and the vehicle speed is still greater than 13 km/h (8 mph).
  • This DTC may also set falsely if the yaw rate sensor is replaced without first following the diagnostic table below. Whenever a new yaw rate sensor is installed, the old sensor must be disconnected, the ignition turned ON for 5 seconds and then OFF, and then the new sensor connected.
  • Inspect the vehicle for proper wheel alignment. Ensure the vehicle does not pull toward the left or right while driving straight forward on a level surface.
  • Communicate with the customer to determine the conditions under which the message center displays the service stability system message. Learning the conditions under which the DTC sets may help you duplicate the failure.
  • Use the Snapshot function on the scan tool in order to assist you in locating an intermittent malfunction.
