Pinpoint Test B: Poor Image Quality - Vehicles With Rear Only Parking Aid Camera

NOTE: Before disconnecting the camera, verify the connector is properly seated and latched.

Refer to Parking Aid for schematic and connector information.

Normal Operation and Fault Conditions

The video signal is transmitted from the camera to the APIM on shielded, twisted pair circuits. Refer to: Parking Aid - System Operation and Component Description .

Possible Sources
- Dirty or scratched camera lens concern
- Wiring, terminals or connectors concern
- Fuse
- DCDC concern
- Rear parking aid camera concern
- APIM concern
- Interference from other sources

B1 CHECK AND CLEAN THE CAMERA LENS

Clean and make sure the rear video camera lens is clear of any debris and scratches.

Test the rear video camera system and inspect the video camera image.

Is the concern still present?

Yes

GO to B2

No	The system is operating correctly at this time. The concern may have been caused by dirt or debris on the camera lens or intermittent electromagnetic interference from an outside source.

B2 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE DCDC (DIRECT CURRENT/DIRECT CURRENT CONVERTER CONTROL MODULE) SELF-TEST
- Using the diagnostic scan tool, perform the DCDC self-test.
Is DTC B1310:11 or B1310:15 retrieved?

Yes Refer to: Direct Current/Direct Current (DC/DC) Converter Control Module .

No GO to B3

B3 CHECK THE VOLTAGE TO THE REAR CAMERA

Ignition OFF.

Disconnect liftgate applique C4488.

Ignition ON.

Measure:

B10 CHECK FOR CORRECT APIM (SYNC MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the APIM connector.

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 APIM connector. Make sure it seats and latches 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, refer to APIM GUIDED ROUTINE

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

B11 CHECK THE REAR PARKING AID CAMERA JUMPER HARNESS

Ignition OFF.

Inspect the liftgate applique jumper harness between the vehicle harness and the rear parking aid camera for:
- Open or short circuits
- Damaged or pushed out pins
- Corrosion

Is the harness OK?

Yes

GO to B12

No	REPAIR the harness as necessary. If the harness cannot be repaired, INSTALL a new liftgate moulding. Refer to: Liftgate Moulding .

B12 CHECK FOR CORRECT REAR PARKING AID CAMERA OPERATION

Ignition OFF.

Disconnect and inspect the rear parking aid camera connector.

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 rear parking aid camera connector. Make sure it seats and latches 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 rear parking aid camera. Refer to: Rear Parking Aid Camera .

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.
