  • The transmission not shifting correctly
K1 VERIFY THE CONCERN
  • Verify the concern

Does the active park assist system not position the vehicle correctly?
Yes
Active park assist sensor(s) damaged, misaligned, or 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 - 1.5L EcoBoost (132kW/180PS) – I3 (Y1) (307-01A Automatic Transmission - 8-Speed Automatic Transmission – 8F35/8F40, Diagnosis and Testing).

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).
