Affected vehicles: 2006 Cadillac STS equipped with AWD and 3.6L V6 engine (LY7)

Situation: Certain affected vehicles have a condition in which the torque monitoring functions of the electronic throttle control (ETC) are not enabled. These functions can limit engine speed and torque if unusual engine control module (ECM) hardware or software failures occur. Without these functions enabled, a persistent ECM failure could result in a throttle opening greater than commanded, like the pedal and throttle position sensors and wiring, are functioning properly and will limit engine torque if a malfunction is detected.
