Possible Causes of C1804 Code in Nissan Vehicles
The C1804 code in Nissan vehicles refers to an air suspension vehicle height adjustment issue. This code indicates that there is a problem with the air suspension system, which is responsible for adjusting the vehicle’s height based on the load and road conditions. Here are some of the possible causes of the C1804 code:
- Faulty height sensor: The height sensor is responsible for measuring the distance between the suspension and the ground. If the sensor is faulty, it may send incorrect signals to the suspension system, causing it to malfunction.

- Worn-out suspension components: If the suspension components, such as the air springs or shock absorbers, are worn out, they may not be able to provide the required support to the vehicle, causing the system to malfunction.
- Electrical issues: The C1804 code may also be caused by electrical issues, such as damaged wiring or a faulty control module.
It is essential to diagnose the root cause of the C1804 code to fix the issue correctly. A professional mechanic can use a scan tool to read the code and perform a visual inspection of the suspension system to identify the problem. Once the problem is identified, the mechanic can replace the faulty components or repair the electrical issues to fix the C1804 code.
