Below are the common symptoms and solutions for electric tailgate issues:
Power Supply Issues: Verify that the power source is correctly connected to the tailgate system. Inspect the vehicle’s wiring harness for any damage or loose connections.
Blown Fuse: Check the fuse box for blown fuses related to the tailgate operation. If a fuse is blown, replace it with one of the same amperage and inspect for underlying causes.
Poor Ground Connection: A faulty ground connection can prevent the system from functioning. Ensure that the ground wire is securely connected to the chassis and free from corrosion.
Incorrect Lock Detection Line Connection: Misconnections can disrupt functionality. Inspect the wiring diagram and reconnect the lock detection line according to specifications.
Insufficient Battery Power: If the vehicle battery is weak, it may not provide enough power. Test the battery voltage and recharge or replace it if necessary.
Damaged Control Box: A malfunctioning control box can lead to failure. Conduct diagnostics and replace the control box if it shows signs of damage or malfunction.
Bracket Installation Issues: Improperly installed brackets can lead to misalignment. Ensure that all brackets are installed as per the manufacturer’s guidelines and that screws are properly tightened.
Missing Waterproof Tape and Interior Panel: Installing waterproof tape and the interior panel is crucial to prevent moisture ingress. Ensure all sealing components are correctly fitted.
Incorrect Installation of Latch Parts: Misalignment in latch components can affect closing. Reinstall latch parts ensuring they fit snugly with the vehicle's structure.
Tailgate Rubber Blocks Not Lowered: If rubber blocks aren’t adjusted correctly, they may prevent proper closing. Adjust their position to allow smooth operation.
Inconsistent Gap Between Tailgate and Body: Prior to installation, carefully measure and compare the gap to ensure uniformity after installation. Adjust as necessary to maintain aesthetic and functional integrity.
Secondary Lock Not Engaging: Proper engagement is essential for security. Ensure the original vehicle lock is activated before adjusting the buffer rubber on the lock hook for a proper fit.
Incorrect Lock Detection Line Connection: Proper wiring is essential. Follow installation instructions to reconnect the lock detection line correctly.
Faulty Electric Latch Connection Line: Inspect the electric latch's wiring for any damage or disconnection, and repair as needed.
Vehicle Fuse Failure: Regularly check and replace fuses as part of routine maintenance to prevent operational issues.
Cable Obstruction or Too Tight Bend: Cables should be free from any obstructions. Ensure that bends are gentle to avoid damaging the insulation or wiring.
Damaged Cable, Electric Latch, or Control Box: Conduct thorough diagnostics to identify damaged components and replace them promptly to restore function.
Tailgate Switch Detection Line Connection Issues: Inspect and repair grounding issues in the tailgate switch detection line to ensure reliable operation.
Stuck Buttons: Regularly check for obstructions around buttons that could prevent them from being pressed or reset.
Improper Connection of Strut Cable: Ensure the strut cable is firmly connected and that the Hall effect sensor is functioning correctly for accurate operation.
Incorrect Lock Detection Line Connection: As with other components, ensure that the lock detection line is properly connected following installation guidelines.
Issues with Control Box Ground or Power Lines: Inspect for loose connections or damage in the control box's ground or power lines and repair as necessary.
Damaged Strut or Control Box: If diagnostics reveal faults, replace struts or control boxes to restore proper functionality.
Vehicle Not Unlocked: Always ensure the vehicle is unlocked before attempting to open the tailgate. Use the key fob or physical key if necessary.
Incorrect Lock Detection or Drive Line Connection: Ensure that the wiring is connected according to the installation manual to enable proper communication between components.
Vehicle Fuse Failure: Regular maintenance should include checking fuses associated with the tailgate for signs of wear or damage.
Damaged Control Box: If other checks do not resolve the issue, replace the control box as it may be failing to process commands.
Incorrect CAN Line and Lock Detection Line Connection: Reconnect these lines as per the installation instructions to ensure proper functionality.
Incorrect Tailgate Switch Detection Line Connection: Properly reconnect the tailgate switch detection line to enable remote operation.
Faulty Control Box or Remote: Check both the remote and control box for functionality. Replace components if necessary, ensuring the remote's battery is charged.
Modification Impact: Verify whether any aftermarket modifications have affected the tailgate system. Adjust settings as needed to restore functionality.
Changed CAN Information: If changes to the vehicle’s electronic settings have occurred, revert them to factory settings to restore normal operations.
Incorrect Tailgate Switch Detection Line Connection: Follow installation instructions to ensure correct connections are made.
Button Connection Line Issues: Inspect and repair any damaged or loose wiring associated with the front button.
Damaged Button: If the button is unresponsive, replace it to restore functionality.
Rear Button Cable Connection Issues: Regularly inspect cable connections for wear or disconnection and repair as needed.
Incorrect Tailgate Switch Detection Line Connection: Ensure proper connections as per installation specifications for reliable operation.
Damaged Button: Replace any damaged buttons to ensure consistent operation.
Incorrect Height Memory Position: Ensure the set height is within the control box's memory limits. Adjust if necessary.
Initialization Not Completed: After setting the memory, ensure a tailgate closing operation is performed to finalize the initialization process.
Conduct a comprehensive check of all vehicle systems post-installation. Confirm that the liftgate has not interfered with other components. Address any discrepancies immediately to maintain vehicle integrity.
