Pro Trailer Back Up Assist

The PTBA system is controlled by the PSCM and, when activated, aids the driver in steering the vehicle with a trailer attached while driving in REVERSE. The PTBA system is comprised of several systems and modules working together to aid in vehicle and trailer control. The presence of certain Diagnostic Trouble Codes (DTCs) in any of those modules or systems may keep the active park assist system from being enabled or may disable the system if currently being used.
