Symptom Chart

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .

NOTE: If using a targeting sticker rule out any parking aid camera system concerns prior to diagnosing the PTBA system.

NOTE: The customer trailer needs to be connected to the vehicle to properly diagnose a PTBA system concern.

NOTE: Low battery voltage is a condition that prevents the PTBA system from operating. Verify the battery voltage and condition if the system is not available prior to diagnosing the PTBA system.

NOTE: Anytime a camera or any body component that a camera is attached to is removed or adjusted, carry out the 360 degree view camera alignment following the repair.
