Pinpoint Test B : Poor Image Quality

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before disconnecting the rear parking aid camera or jumper harness, verify that the connectors are properly seated and latched.

Refer to Parking Aid for schematic and connector information.

Normal Operation and Fault Conditions

Refer to: Parking Aid - System Operation and Component Description .

Possible Sources
- Fuse
- Dirty or scratched camera lens
- Wiring, terminals or connectors
- Interference from other sources
- Rear parking aid camera
Visual Inspection and Pre-checks
- Verify that the rear parking aid camera lens is in good condition and free of any debris.
- BJB fuse 58 (10A).

B1 CHECK AND CLEAN THE REAR PARKING AID CAMERA LENS

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

Test the rear parking aid camera system while observing the rear parking aid 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 THE VOLTAGE TO THE CAMERA

Ignition OFF.

Disconnect Rear Parking Aid Camera C4360.

Ignition ON.

Measure:

Is the resistance greater than 10, 000 ohms?

Yes

GO to B9

No	REPAIR the circuits.

B9 CHECK FOR CORRECT REAR PARKING AID CAMERA OPERATION

Ignition OFF.

Disconnect and inspect the rear parking aid camera connector and related in-line 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 rear parking aid camera connector and related in-line 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new rear parking aid camera. Refer to: Rear Parking Aid Camera .. TEST the system for normal operation. If the concern is still present, GO to B10

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.

B10 CHECK FOR CORRECT APIM (SYNC MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the APIM connector and related in-line connectors.

Repair:
- Corrosion (clean module pins or install new connectors or terminals)
- Damaged or bent pins (install new terminals or pins)
- Pushed-out pins (install new pins as necessary)

Reconnect the APIM connector and related in-line 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to APIM Guided Routine Testing .

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