Component Description

WARNING: This page is about a different car, the 2015 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

IPMA 

The IPMA is integral to the interior rear view mirror. The IPMA contains a forward-looking camera that is used to detect the position of the vehicle within the lane.

The IPMA requires PMI and camera alignment when replaced.

Camera Windshield Defrost Heater 

The camera windshield defrost heater is a resistive-type heater grid that is adhered to the inside of the windshield directly in front of the IPMA camera.

The camera windshield defrost heater uses a jumper harness between the component and the vehicle harness. Before replacing the camera windshield defrost heater or IPMA for a camera windshield defrost heater concern, verify the integrity of the wiring, connectors and terminals on the jumper harness.

Lane Keeping System Switch 

The lane keeping system switch is a normally open, momentary contact switch that, when pressed, grounds the lane keeping system switch input circuit from the IPMA.
