Normal Operation and Fault Conditions
The attenuation time for the rear parking aid sensors is the time required for a sensor to detect the distance to an object expressed in milliseconds (ms). If the parking aid sensor signal or the attenuation time is out of normal range, the PAM stores a corresponding DTC and disables the rear parking aid system.
