All of the following are typical sensors used by the electronic stability control system, EXCEPT: Select one: a. the yaw sensor. b. the steering angle sensor. c. the roll-rate sensor. d. the crash frontal sensor.

The correct answer is d. the crash frontal sensor.<br /><br />The electronic stability control (ESC) system typically uses sensors such as the yaw sensor, steering angle sensor, and roll-rate sensor to monitor the vehicle's dynamics and make adjustments to maintain stability. The crash frontal sensor is not typically used by the ESC system for this purpose.
