So i got an air leak that myself and/or no one has been able to track down for some time now. It's around 60-90 psi/hr when the truck is off - lower when empty or bob tailed higher when loaded. The compressor keeps up with it while it's running, cycles on/off maybe every 15 or so min. Not ideal but is what it is at the moment. The BIGGEST annoyance right now is that if the auto-run is active the air gauges are active and thus the low pressure warning is active thus about every hour with the APU running sleeper climate controls and the auto-run on you have to wake up and turn the truck on manually to charge the tanks or alternatively run the APU without the auto-run and just let it run the aux batts down.
THE QUESTION I'M GETTING TO IS: Can the gauges/warning alarm be programmed via the ECM or BCM to NOT be active when the trucks auto-start is engaged? And/or any tips on tracking down this air leak would be more than welcome.
Thx!
