My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

This can be due to a leak in the lines or shocks causing this fault here or a possible fault with the pump/compressor as I have seen both of these cause this type of fault here.The system will need tested and inspected for any leaks and to see if the pump/compressor is the cause here needing replaced.In some cases it can be a pressure sensor at fault needing replaced sending an incorrect signal.But this will need tested further to pinpoint and repair the cause here.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
