Shengda four-wheel deflection fault code cannot be cleared.

There may be several reasons for this:

1. The cruise control switch is faulty: the cruise control fault code cannot be eliminated. It may be because the cruise control switch is faulty and needs to be replaced.

2. Brake pedal position switch failure: If the brake pedal position switch fails, the fault code may not be eliminated and needs to be replaced.

3. Failure of electronic throttle system: Failure of electronic throttle system may also lead to failure code. It is necessary to check whether the throttle valve is stuck by carbon deposit, and remove it for inspection.

4. Generator failure: Generator failure will also lead to the failure code can not be ruled out, so it is necessary to check the generator.

5. The data connection of the controller area network (CAN) is closed: the data connection of the controller area network is closed, which will also cause the fault code to be unable to be eliminated. You can check whether the data connection is abnormal.
