Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
This is normally caused by either a bad height sensor, or a bad air compressor for the rear shocks. If you have a Bad Height Sensor, it will not tell the computer the proper readings to allow it to turn on.
To determine this, a scanner is used to turn the compressor on manually to see if it responds. If it does not respond, then power and ground signals are checked at the compressor when commanded to turn on. If power and ground is present, then you have a bad Air Compressor for rear air ride.
Do you have any more questions on this?
