Normal Operation
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
The Parking Aid Module (PAM) calculates the distance to an object using 4 ultrasonic sensors mounted in the rear bumper. The parking aid sensors can detect obstructions in the path behind the vehicle.
The attenuation time for the rear parking aid sensors is the time required for a sensor to detect the distance to an object expressed in milliseconds (ms). A fault condition occurs when the signal or the attenuation time is out of normal range.
DTC FAULT TRIGGER CONDITIONS
| DTC Description | Fault Trigger Conditions |
|---|---|
|
A continuous and on-demand DTC that sets when the right rear outer parking aid sensor has internally failed or has an incorrect attenuation time. |
|
A continuous and on-demand DTC that sets when the right rear inner parking aid sensor has internally failed or has an incorrect attenuation time. |
|
A continuous and on-demand DTC that sets when the left rear outer parking aid sensor has internally failed or has an incorrect attenuation time. |
|
A continuous and on-demand DTC that sets when the left rear inner parking aid sensor has internally failed or has an incorrect attenuation time. |
This pinpoint test is intended to diagnose the following:
