Active Park Assist
Some vehicles equipped with EPAS may also be equipped with active park assist. The active park assist system is controlled by the Parking Aid Module (PAM) and, when activated, can detect a parking space and steer the vehicle into the space by sending commands to the EPAS gear (the driver still controls the throttle, brakes and transmission). The active park assist system is comprised of several systems/modules that work together to aid in parallel parking maneuvers, the presence of certain Diagnostic Trouble Codes (DTCs) in any of those systems/modules may either keep the active park assist system from being enabled or may disable the system if currently being used.
