Where is the control module of modern Geyue tailgate?
(1) electric tailgate actuator assembly: it is mainly composed of actuator motor, push rod, rack mechanism and bracket, and is responsible for opening and closing tailgate.
(2) Electric tailgate control module.
(3) Tailgate electric lock mechanism: mainly includes unlocking motor and locking motor. When the motor opens the tailgate, the unlocking motor is used to control the unlocking of the tailgate lock. When the motor closes the tailgate, the locking motor is used to tighten and close the tailgate.
(4) Electric tailgate buzzer: When the shift lever is not in P position, the tailgate cannot be opened due to unknown resistance, or when the electric tailgate switch is turned on under abnormal working conditions, the buzzer will give an alarm prompt.
(5) Anti-pinch bar: a rubber strip with rigid switch, located at the left and right sides of the tailgate. When the motor closes the tailgate, the anti-pinch bar is responsible for detecting obstacles. When the anti-pinch bar is resisted, the motor will reverse, and the tailgate will stop closing and return to the open position.
(6) Electric tailgate switch: ① Remote control switch. Press and hold the tailgate button on the remote controller for more than 2 seconds to open or close the tailgate remotely. (2) Dashboard switch. On the dashboard side of the driver, the driver can control the opening or closing of the tailgate from the seat. ③ Handle switch outside the tailgate. Installed on the handle outside the tailgate, it is mainly used to open the tailgate. ④ Tailgate trim panel switch. Located under the tailgate trim, it is mainly used to close the tailgate.
(7) Electric tailgate closing switch: located in the glove box on the co-pilot's side, used to limit the operation of the tailgate external handle switch and tailgate decorative switch. The assembly of electric tailgate system greatly improves the convenience of Veracruz SUV. But it also increases the content and difficulty of maintenance. In practical work, we have encountered several typical fault cases. Now we will sort out these cases and share them with our peers in the maintenance industry.
Example:
Model: equipped with 3.8L engine.
Mileage: 200 kilometers.
Fault phenomenon: the customer reported for repair, pulled the handle outside the tailgate, and could not open the tailgate.
Fault diagnosis: firstly, confirm the fault phenomenon according to customer complaints. When the switch on the tailgate handle is pressed to open the tailgate, there is no sign of the tailgate opening. Use the remote control, and then press the tailgate control switch on the dashboard, the tailgate can be opened and closed normally and automatically. When the tailgate is in the open state, the tailgate can be automatically closed normally. Through a series of tests, we have basically confirmed that the fault of the car is that the handle switch outside the tailgate cannot open the tailgate. Then we tested the electric tailgate system with modern automobile diagnostic instrument HI-DS, and no fault code was stored. When reading the data stream, we found that no matter how many times the switch of the tailgate handle is pressed, the corresponding data stream is in the closed state (as shown in Figure 2), while other switches will change to open or close with the operation of the switch. This means that the electric tailgate control module has not received the switch signal of the tailgate external handle, but in the electric tailgate system of Veracruz SUV, the signals of the tailgate external handle switch and the tailgate interior trim panel switch are first input to the body control module BCM.
