How to solve the Buick fault code 128?

[OJayce]

The meaning of the code 128 in the Buick Yinglang is that the engine hood is not closed tightly. Simply closing the engine hood properly should resolve the issue. If it cannot be closed, possible reasons include the hood cable not retracting, deformation of the hood lock, loose screws affecting the lock mechanism's position, misalignment of the lock mechanism, or a broken lock hook. More details are as follows: 1. Method to close the engine hood: To close the engine hood, first lower the support rod, then gently lower the hood by hand. When it is about 20 cm from the closing point, release your hands and let the hood fall freely. At this point, you should hear a crisp closing sound. If the hood is not completely closed, the gaps at the front and rear of the hood will be inconsistent, and you will need to reopen and lower the hood again. 2. Precautions: It is important to avoid opening or closing the hood with one hand or on one side only, as this can cause uneven gaps on both sides of the hood. Also, do not press the hood forcefully with your hands, as this may cause the hood to dent.
