There are two cases, and there are two cases. Due to the relatively similarity of the fault, pay attention to
1, the steering wheel is not correct, but the vehicle does not run
[123 ] 2, the steering wheel is not correct, causing the vehicle to run mild
1, if the steering wheel is not correct, but the vehicle does not run, this is generally not a failure phenomenon, due to the disassembly of the steering wheel or the direction of the wrong tooth, cause the steering wheel slight 2- 3 degrees, this situation requires the disassembly of the steering wheel to re-adjust a tooth, if the steering wheel is still awkward, you can repeat the last step to adjust a teeth, but no need to adjust, it is not recommended to adjust more than 3 teeth, because the adjustment is too much The steering angle sensor is damaged.
If the steering wheel is not correct, but the vehicle does not run, if it is a phenomenon that has just changed the electronic steering machine or just replaced the turntable control unit, this steering wheel is needed to reset and learn the steering machine control unit. Process, general electronic steering machine also has self-learning process.
2, the steering wheel is not correct, causing the vehicle to run slightly, if it is a vehicle with air damping, it is necessary to measure the height of the four shock absorber, and the focus checks if the left and right height is consistent, if not consistent, correct the chassis system Second, it is necessary to check whether the pressure of the 4-wheel tire is normal, and the conventional tire pressure is 2 bar-2.5 bar. If the fault is still, it is necessary to adjust the vehicle, according to the positioned data to adjust the front lead angle, outer flange, and then tilt angle, it is strictly forbidden to adjust the front of the vehicle, the outer legeity, and the angle angle, because abnormal Data adjustment can cause the tire partial, and the steering wheel is not returned.
