Hi Alex, A C1503 code is usually going to be caused by a weak air compressor. The system should be inspected for leakage by listening for leaks when the compressor is running and by spraying all of the lines and air bags with a soapy water solution. If no leaks are found the compressor will likely need replacing.

Let me know if you have any questions.
