A vehicle equipped with an air ride suspension will not lower when necessary. Which could cause this problem?

In a vehicle with air ride suspension, the system relies on various components to adjust the ride height by either inflating or deflating the air bags. When the vehicle does not lower as expected, one key component that could be at fault is the sensor.

The sensor’s role is to monitor the vehicle’s height and provide feedback to the air suspension control module. If the sensor is malfunctioning or providing incorrect readings, the control module may not receive the necessary information to adjust the air suspension appropriately, which can prevent the vehicle from lowering when it should.

In contrast, while other components such as the compressor, compressor relay, and fuse are crucial for the FUNCTION of an air suspension system, a failure in these components is typically associated with the inability to inflate the system or maintain height, rather than directly affecting the lowering function. Therefore, a faulty sensor is indeed a likely reason for the vehicle's inability to lower as required.
