Component Description

IPMA 

The IPMA communicates on the HS-CAN and controls the lane keeping system. 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.

IPMA Camera Heated Windshield Element 

The IPMA camera heated windshield element is a resistive-type heater grid that is integrated into the windshield and located directly in front of the IPMA camera. The IPMA camera heated windshield element cannot be replaced separately from the windshield.

The IPMA camera heated windshield element uses a jumper harness between the component and the vehicle harness. Before replacing the windshield, the BCM or the IPMA for a IPMA camera heated windshield element 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 momentary contact switch located on the LH steering column multifunction switch. The lane keeping system switch inputs directly to the SASM, which forwards the switch state message to the BCM via a LIN.
