Symptom Chart
Condition Possible Sources Action
  • A module does not respond to the scan tool
  • Fuse
  • Wiring, terminals or connectors
  • PAM
  • The active park assist switch does not respond when pressed and the APIM does not display the active park assist message in the centerstack infotainment center
  • Refer to the Diagnostic Routine
  • "Active Park Assist Fault" message displayed in the centerstack infotainment display
  • Refer to the Diagnostic Routine
  • The IPC message center displays an "ACTIVE PARK NOT AVAILABLE" message
  • Any door or luggage compartment (with exception of the driver door) was ajar when the system was activated
  • AdvanceTrac® was off when the system was activated
  • An ABS event or AdvanceTrac® occurred at the same time that the system was activated
  • The active park assist system is not available if any door (except the driver door) is ajar, if the AdvanceTrac® is off, if an ABS event or AdvanceTrac® event occurred when the system is being activated. The system is operating correctly at this time.
  • The active park assist system does not position the vehicle correctly
  • Dirty or iced over active park assist sensor(s)
  • CLEAN the front bumper cover and active park assist sensors with high-pressure water.
    • Active park assist sensor bezel(s) or active park assist sensor(s) locked into the front bumper incorrectly
    • REMOVE and correctly INSTALL the active park assist sensor(s) as necessary.
      • Active park assist sensors are not aligned correctly
        • Active park assist sensors are affected by a sudden change in the outside air temperature
        • The temperature around the vehicle can change quickly, such as being parked in a heated garage and driven into the cold or just leaving a car wash. As a result, the outside air temperature displayed in the vehicle may not be close enough to the actual temperature. The active park assist system relies on correctly sensing the outside temperature to precisely position the vehicle. No action is required.
          • The tires are not inflated to the correct pressure, the tires are not the same size or the tires are not OEM tire sizes being used.
          • INSPECT the tires condition, pressure and size. A considerably worn tire positions the vehicle far from the curb. A larger size tire positions the vehicle closer to the curb. REPAIR or REPLACE tire(s) as necessary.
            • The driver allowed the vehicle to roll in the opposite direction of the transmission (such as rolling forward with reverse gear selected).
            • INFORM the customer not to allow the vehicle to roll in the opposite direction when operating the active park assist system. REFER to the Owner's Literature.
              • An irregular curb is present along the parking space.
              • The system may not be able to align the vehicle to curbs that are damaged, very shallow or covered by debris. If this is the circumstance, the system aligns the vehicle relative to the front bordering object.
                • The vehicles or objects bordering the parking space are not position correctly.
                • The system aligns the vehicle to the front vehicle or object when the system does not detect a curb.
                  • One of the parked vehicles has a high attachment, such as a salt spreader or moving truck bed, that the sensors cannot detect.
                  • High attachments may not be detected by the system.
                    • The parking space length or parked objects position has changed after the vehicle has passed the parking space.
                    • The system scans the parking space as the vehicle is driven by the available spaces. Therefore, the system cannot detect if the parked vehicle or objects position has changed after the parking space has been scanned. No action needs to take place at this time.
                    • The active park assist system does not offer available parking spaces
                    • The vehicle is being driven too close or too far from the adjacent vehicle and/or objects
                    • The vehicle must be driven greater than 41 cm (16 in) and less than 150 cm (60 in) from the adjacent vehicle.
                      • The parking space available is too small
                      • The active park assist system only allows available parking spaces that are larger than 1.2 times the size of the vehicle. The system is operating correctly at this time.
                        • There may not be enough room to maneuver the vehicle into the available space
                        • There needs to be enough space on the opposite side of the vehicle to allow the front of the vehicle to swing out as the operator backs into the space.
                          • An obstruction may be covering the active park assist sensor(s)
                          • INSPECT and CLEAN the active park assist sensor(s). REMOVE any obstruction that is covering the sensor(s).

                            • corrosion (install new connector or terminals - clean module pins)
                            • damaged pins - install new terminals/pins
                            • pushed-out pins - install new pins as necessary
                          • Reconnect the PAM connector. Make sure it seats and latches correctly.
                          • Operate the system and determine if the concern is still present.

                          Yes
                          CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new PAM .

                          No
                          The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
