Any idea where this module might be? I also discovered code 1738, ground short. I read that you MUST replace the compressor on the vehicle but my problem was just one of the wires Arnott issued to me has a bad connection to the sensor. I have a temp fix on it right now, so the car doesn't toss a 1738 anymore, just the 1780. The air ride will engage if I "clear code". The 1780 comes back immediately and the compressor will inflate the rear shocks, however it will not come back on unless i "clear codes" again. Any help with this particular issue would be great. is it possible the 1780 is the computer to not engage the compressor after?
