Advanced Parking Assist System Operational Checks

The scan tool Advanced Parking Assist Disable History 1 - 8 data can be used to diagnose a malfunction within the parking assist system or an intermittent concern. The following is a brief description of potential causes which may aid in diagnosis. For each potential issue, perform an appropriate inspect of the component or system and refer to the specific service information subsection related to that system for further diagnosis:

• Advanced Parking Assist Switch Pressed - The advanced parking assist switch has been pressed a second time, aborting the function.
• Advanced Parking Assist Switch Malfunction - The advanced parking assist is stuck closed or has been held down.
• Interrupted by Driver - The advanced parking assist operation has been aborted by the driver by interfacing with the steering, brake, or accelerator.
• Info Display Control Malfunction - The advanced parking assist system is not able to provide instructions on the driver information center
• Door Open - A door has been opened.
• Parking Brake Malfunction - A malfunction has been detected in the electric parking brake system.
• Vehicle Dynamics System Status Not Plausible - An implausible scenario between the steering angle sensor, yaw sensor, and lateral/longitudinal accelerometer has been determined.
• Steering Response Malfunction - The steering system has not responded as expected to a steering command.
• Automatic Brake Response Malfunction
• Transmission Response Malfunction - The transmission has not responded as expected to a shift command.
• Automatic Braking Apply Response Not Plausible - An implausible scenario between a brake apply command and vehicle deceleration has been determined.
• Vehicle Movement Detected During Brake Applied Request - Vehicle movement has occurred while the brakes are commanded to apply.
• Chime Malfunction - A fault exists with the vehicle chime. Check for DTCs.
• Wheel Speed Direction Signal Invalid - Identified wheel directional travel does not match intended travel direction.
• Vehicle Speed Invalid - The vehicle is unable to determine the vehicle speed.
• Attached Object Detected - An object has been determined to be attached to the front and rear of vehicle.
• Parking Maneuver Vehicle Speed Exceeded - The vehicle has exceeded the maximum allowable speed for the parking maneuver.
• Vehicle Speed Too High to Search for a Parking Space - The vehicle has exceeded the maximum allowable speed to search for a suitable parking spot.
• Number of Parking Maneuvers Exceeded - The maximum number of parking attempts for a single maneuver has been exceeded.
• Parking Space Too Small - The vehicle has determined the space for the attempted parking maneuver is too small.
• Vehicle Not Following Parking Space Path - The vehicle is unable to follow the intended path of the parking maneuver.
• Yaw Angle Above Threshold - The expected yaw angle for the parking maneuver has been exceeded.
• Steering Angle Deviation Above Threshold - The expected steering angle for the parking maneuver has been exceeded.
• Object Detected on Both Sides of Vehicle - An object has been detected on both the left and right side of the vehicle.
• Object Detected in Alert Zone - An object has been detected in the vehicle's path.
• Sensor Blocked - One of the following conditions may be present:
  • One or more of the sensors may be blocked by snow, mud, ice, or other debris. This might happen after going through a car wash in cold weather.
  • Silicone insulator surrounding sensor maybe missing, cut, or twisted.
  • Improperly installed sensor, sensor maybe be crooked due to a tight wire harness.
  • One or more of the sensors may be scratched or the paint maybe chipped.
  • Excessive paint thickness on a sensor may cause an excessive sensor ring time. When replacing or refinishing a sensor, do not apply an excessive amount of paint or clear coat.
• Steering Angle Signal Invalid - The vehicle is unable to determine the steering angle.
• Invalid Gear - The vehicle has determine a plausibility fault exists with the transmission range.
• Incorrect Power Mode - The vehicle is in an incorrect power mode for parking assist operation.
