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

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

Parking Aid for schematic and connector information.

Normal Operation and Fault Conditions

The video signals are transmitted from each camera to the IPMB on a coaxial cable. The IPMB 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 .

Possible Sources
- Dirty or scratched camera lens
- Fuse
- Wiring, terminals or connectors
- Coaxial cable
- Camera
- IPMB
- APIM concern
Visual Inspection and Pre-checks
- Inspect the camera lenses for damage, dirt, debris and scratches.

Ignition OFF.

Disconnect and inspect the IPMB connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the IPMB connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new IPMB.

No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
