Pinpoint Test F: Poor Image Quality - Vehicles With 360 Degree Camera

NOTE: Before disconnecting any of the cameras, verify the connectors are properly seated and latched.

Refer to PARKING AID for schematic and connector information.

Normal Operation and Fault Conditions

The video signals are transmitted from each camera to the IPMA on a coaxial cable. The IPMA processes the image data and sends a single video image to the APIM on shielded, twisted pair circuits. REFER to: Parking Aid - System Operation and Component Description

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
IPMA C1001:97	Vision System Camera: Component Or System Operation Obstructed Or Blocked	A continuous and on-demand DTC that sets in the IPMA when a camera is blocked or obstructed.
