The calibration of the old Lincoln navigator module failed and the pneumatic test failed.

Hello, I would like to ask the reason why the calibration of the old Lincoln navigator module failed and the pneumatic test failed. Calibration of the old Lincoln navigator module failed. The reasons for the failure of air pressure test are as follows:

1, the shock absorber leaks, and the air suspension cannot be lifted.

2. The calibration of damping module is invalid.

3. The catheter air pump leaks. According to the Pacific Auto Network, the calibration of the old Lincoln Navigator module failed, and the reasons for the failure of the air pressure test are as follows:

1, the shock absorber leaks, and the air suspension cannot be lifted.

2. The calibration of damping module is invalid.
