  Symptom Chart: Active Park Assist


Condition Possible Sources Actions
A module does not communicate with the diagnostic scan tool
  • Fuse
  • Wiring, terminals or connectors
  • Module
 
REFER to: Communications Network (418-00 Module Communications Network, Diagnosis and Testing).
The active park assist system does not activate when the active park assist switch is pressed Refer to the Pinpoint Test   GO to Pinpoint Test H
The centerstack infotainment display and/or the IPC message center display shows an active park assist fault message Refer to the Pinpoint Test   GO to Pinpoint Test I
The centerstack infotainment display shows the active park assist not available message AdvanceTrac® was off when the system was activated
  • The active park assist system is not available if the AdvanceTrac® is off or if an ABS or AdvanceTrac® event is in progress when the system is being activated by the driver.
An ABS or AdvanceTrac® event was in progress when the system was activated
  • The battery was recently disconnected
  • The PSCM and/or the ABS module were recently reprogrammed
  • The vehicle is brand new from the manufacturing plant (and has not been driven above 50 km/h (30 mph) with minimal steering input for 30 seconds
The active park assist system is not available immediately after a battery disconnect or if the PSCM and/or the ABS module were recently reprogrammed. PERFORM the following: drive the vehicle straight on a flat/smooth road above 50 km/h (30 mph) with minimal driver steering input for 30 seconds. Abort this step at any time to maintain safe driving, and repeat the process if required. If completed correctly, active park assist will be available upon pressing the active park assist switch.
The active park assist system does not position the vehicle correctly
  • Active park assist sensor(s) locked into the bumper incorrectly
REMOVE and correctly INSTALL the active park assist sensor(s) as necessary.
REFER to: Front Active Park Assist Sensors (413-13C Parking Aid - Vehicles With: Active Park Assist, Removal and Installation).
REFER to: Rear Active Park Assist Sensors (413-13C Parking Aid - Vehicles With: Active Park Assist, Removal and Installation).
  • Dirty or iced over active park assist sensor(s)
CLEAN the bumper covers and active park assist sensors with high-pressure water.
  • Active park assist sensors affected by a sudden change in ambient air temperature
The temperature of the air around the vehicle can change rapidly, such as the vehicle being driven into or out of a parking garage or car wash. As a result, the air temperature displayed in the vehicle may not be close enough to the actual ambient air temperature. The active park assist system relies on accurately sensing the ambient air temperature to compensate the sensors. 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 the OE (original equipment) size.
INSPECT the tire 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 when the reverse gear is 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 objects bordering the parking space.
  • A vehicle or object bordering the parking space is not aligned with the parking space.
The system aligns the vehicle to the objects bordering the parking space when a curb is not detected.
  • One of the parked vehicles has an elevated attachment, such as a salt spreader or moving truck bed that the sensors cannot detect
Elevated 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 transmission not shifting correctly
 
REFER to: DTC Chart and Pinpoint Tests - 3.0L EcoBoost (307-01A Automatic Transmission - 10-Speed Automatic Transmission – 10R60, Diagnosis and Testing).
The active park assist system does not position the vehicle correctly
  • Active park assist sensor(s) damaged or misaligned
INSTALL a new active park assist sensor(s) as necessary.
REFER to: Front Active Park Assist Sensors (413-13C Parking Aid - Vehicles With: Active Park Assist, Removal and Installation).
REFER to: Rear Active Park Assist Sensors (413-13C Parking Aid - Vehicles With: Active Park Assist, Removal and Installation).
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 40 cm (16 in) and less than 152 cm (60 in) from the adjacent vehicle.
  • The parking space available is too small
  • For parallel parking, the active park assist system only allows available parking spaces that are larger than 1.2 times the length of the vehicle. The system is operating correctly at this time.
  • For perpendicular parking, the active park assist system only allows available parking spaces that are larger than vehicle width + 90 cm (3 ft) wide. 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).
  • The active park assist sensor(s) isolator ring is missing, damaged or misaligned
INSTALL a new active park assist sensor(s) as necessary.
REFER to: Front Active Park Assist Sensors (413-13C Parking Aid - Vehicles With: Active Park Assist, Removal and Installation).
REFER to: Rear Active Park Assist Sensors (413-13C Parking Aid - Vehicles With: Active Park Assist, Removal and Installation).
  • The Outside Air Temperature (OAT) sensor does not indicate accurate temperature readings
DRIVE the vehicle to allow airflow over the Outside Air Temperature (OAT) sensors until the centerstack infotainment display temperature reading is reflective of the actual outside ambient temperature.
The centerstack infotainment display shows POA NOT AVAILABLE when the turn signal is used during a parallel park out assist maneuver
  • The occupied parking space is too small
The active park assist system only offers the parallel park out assist feature when the occupied parking space is at least 1.2 times the length of the vehicle. The system is operating correctly at this time.
  • An obstruction may be covering the front active park assist sensor(s)
INSPECT and CLEAN the front active park assist sensor(s). REMOVE any obstruction that is covering the sensor(s).
  • No object or vehicle is detected directly in front or behind the occupied parking space
The parallel park out assist feature is only available when an object or vehicle is detected within 1.5 m (5 ft) of either the front or the rear bumper. The system is operating correctly at this time.
  • An object or vehicle is detected on the side of the turn signal activation
The parallel park out assist feature displays the message POA NOT AVAILABLE when objects or vehicles are detected within 110 cm (4 ft) in North America and South America or detected within 60 cm (2 ft) in Europe and Asia Pacific on the side of turn signal activation. Passing traffic, pedestrians or other objects may be detected. When the turn signal is activated, VERIFY the desired side has a clearance of at least 110 cm (4 ft) in North America and South America or 60 cm (2 ft) in Europe and Asia Pacific .
The active park assist system does not offer the parallel park out assist feature The vehicle has been driven farther than 2 m (7 ft) after ignition on, or after a parallel park. INFORM customer that the parallel park out assist feature is only an available option immediately after a successful automated parallel park or immediately after ignition on. Driving farther than 2 m (7 ft) after either of these events results in the parallel park out assist not being an available option for the driver to select.
