Question

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.

Explanation:

Electronic stability control (ESC) systems use sensors to monitor vehicle movement and steering input to maintain stability. Yaw sensors track rotational movement around the vertical axis, steering angle sensors detect driver steering input, and roll-rate sensors measure tilt around the longitudinal axis—all are core to ESC function. Crash frontal sensors are designed to detect collisions for airbag deployment, not for ongoing stability control.

Answer:

d. the crash frontal sensor.
