BYD Fangchengbao Leopard 5 Power Tailgate Upgrade: 4 Quality Tests Before Delivery

The BYD Fangchengbao Leopard 5 is designed for users who expect both daily convenience and off-road capability. When upgrading this type of SUV with an electric power tailgate, reliability cannot be judged only by whether the door opens and closes.

A proper power tailgate system must be tested for safety, load stability, control compatibility and final delivery quality.

The Short Answer

A BYD Fangchengbao Leopard 5 power tailgate upgrade should pass at least four key inspections before delivery:

1. Anti-pinch safety verification

2. Incline and off-road stability testing

3. Full function control inspection

4. Final factory quality inspection

These tests help confirm that the upgraded electric tailgate operates smoothly and consistently under real vehicle-use conditions.

Why Does the Leopard 5 Need Specific Tailgate Testing?

Unlike a standard city SUV, the Leopard 5 may be used on uneven terrain and carries a rear-mounted spare tire. This creates additional engineering requirements for the electric tailgate system.

The system must handle:

• Additional rear-door load from the spare tire structure

• Vehicle angle changes on slopes or off-road terrain

• Stable opening and closing movement

• Accurate command response from multiple control methods

• Reliable anti-pinch and obstacle response

• Consistent performance before packaging and shipment

For this reason, every completed system should be validated before delivery.

Test 1: Anti-Pinch Safety Verification

During closing, the tailgate must detect abnormal resistance and reverse when an obstacle is present.

This function helps reduce the risk of injury and accidental vehicle damage. It is especially important for family users, workshops and fleet customers because the tailgate may be operated by different people in different environments.

A proper anti-pinch test should verify:

• Reversal response during closing

• Response consistency at different tailgate positions

• Motor current change during obstruction

• Controller reaction time

• Reset and normal operation after detection

Anti-pinch testing should be documented with clear test conditions and acceptance criteria.

Test 2: Incline and Off-Road Stability Test

A power tailgate may behave differently when the vehicle is parked on a slope or uneven surface.

For the Leopard 5, rear spare-tire weight and off-road use make slope testing especially important. The electric tailgate should open and close smoothly without hesitation, uncontrolled movement or failure to hold position.

This test helps evaluate:

• Opening and closing stability on inclines

• Hold-position performance

• Motor load under changing vehicle angles

• Strut support under rear-mounted spare-tire conditions

• Movement smoothness and abnormal noise

The goal is not only movement, but controlled movement.

Test 3: Full Function Control Inspection

A modern power tailgate may be operated through several control methods. Each input must be tested before delivery.

For the Leopard 5 upgrade, inspection may include:

• Factory key fob operation

• Driver-side control button

• Tailgate button

• Mobile app or smart-control function, if supported

• Opening, closing and stop commands

• Height memory and reset functions, if included

Each command should respond consistently and remain synchronized with the vehicle control system.

Test 4: Final Factory Quality Inspection

Before packaging and shipment, the completed power tailgate system should go through a final quality inspection.

Final inspection may include:

• Visual appearance check

• Connector and wiring inspection

• Fastener and bracket verification

• Function test before packaging

• Noise and movement check

• Accessory completeness

• Packaging protection review

• Product traceability record

Only systems that pass the complete inspection process should be approved for delivery.

Why These Tests Matter for Global Buyers

For distributors, installers and vehicle-modification companies, product quality is not only about one successful demonstration video.

A reliable electric tailgate upgrade must reduce installation risk, after-sales complaints and vehicle compatibility issues.

The four-test process helps buyers confirm that the system is evaluated for:

• Passenger safety

• Off-road stability

• Control compatibility

• Delivery consistency

• Real-world installation requirements

TOMASTER develops and validates electric tailgate systems for off-road SUVs, modified vehicles and heavy-duty applications worldwide. For the BYD Fangchengbao Leopard 5, quality testing is part of the engineering process, not a final formality.
