WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- 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
- Dirty or scratched camera lens
- Wiring, terminals or connectors
- Rear parking aid camera
- APIM
- Interference from other sources
Visual Inspection and Pre-checks
- Make sure the rear video camera lens is clear of any debris.
- B1 CHECK AND CLEAN THE 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 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 THE VOLTAGE TO THE REAR CAMERA
- Ignition OFF.
- Disconnect Rear Parking Aid Camera C4360.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C4360-1 Ground
Is the voltage greater than 11 volts?
Yes GO to B3 No INSPECT BJB fuse 25 (10A). If the fuse is OK, repair the circuit for an open. If the fuse is not OK, REFER to the OEM WIRING DIAGRAMS to identify the possible causes of the short circuit. - B3 CHECK THE CAMERA GROUND CIRCUIT
- Measure:
Positive Lead Measurement / Action Negative Lead C4360-5 Ground
Is the resistance less than 3 ohms?
Yes GO to B4 No REPAIR the circuit. - Measure:
- B4 CHECK THE VIDEO SIGNAL AND SHIELD CIRCUITS FOR A SHORT TO VOLTAGE
- Disconnect APIM C2383A.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C4360-3 Ground C4360-4 Ground C4360-5 Ground
Is any voltage present?
Yes REPAIR the circuit in question. No GO to B5 - B5 CHECK THE VIDEO SIGNAL CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
Are the resistances greater than 10, 000 ohms?
Yes GO to B6 No REPAIR the circuit in question. - B6 CHECK THE VIDEO SIGNAL CIRCUITS FOR A SHORT TO THE VIDEO SHIELD
Are the resistances greater than 10, 000 ohms?
Yes GO to B7 No REPAIR the circuit in question. - B7 CHECK VIDEO SIGNAL CIRCUITS FOR AN OPEN
Are the resistances less than 3 ohms?
Yes GO to B8 No REPAIR the circuit in question. - B8 CHECK THE VIDEO SHIELD CIRCUIT FOR AN OPEN
Is the resistance less than 3 ohms?
Yes GO to B9 No REPAIR the circuit - B9 CHECK FOR CORRECT 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 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.
