cxn613 Posted August 17, 2016 Share Posted August 17, 2016 was wondering if these two buzzers operate at the same location, but just have different audible sounds. Also is there any way to make sure the cluster is the problem? thanks Quote Link to comment https://www.bigmacktrucks.com/topic/46481-cxu-low-air-and-shut-down-buzzer-not-working/ Share on other sites More sharing options...
fjh Posted August 17, 2016 Share Posted August 17, 2016 (edited) .most newer units have the buzzers built into the dash can't mess with it if the low air has quit you may have to add in a low air sensor and a seperate buzzer or buy a new dash for an outrageous amount cheapest to add on!

mcfibb Posted August 18, 2016 Share Posted August 18, 2016 On YouTube, Sergei Dratchev has two videos showing the buzzer location behind the guage cluster on a CXU613. Yours may be the same setup.

cxn613 Posted August 18, 2016 Author Share Posted August 18, 2016 Im liking the add on low pressure sensor and buzzer. I have also lost the beep that sounds when you cycle key switch on, which is the same beep that lets you know cruise is set, or when idle shutdown is about to happen etc. Is this same beep tied into the low air warning buzzer just different audible sounds?

fjh Posted August 21, 2016 Share Posted August 21, 2016 (edited) Buy the old style green buzzer and wire in a low pressure switch at or near the air governor will save you about a grand ! 1 Edited August 21, 2016 by fjh Quote Link to comment https://www.bigmacktrucks.com/topic/46481-cxu-low-air-and-shut-down-buzzer-not-working/#findComment-342976 Share on other sites More sharing options...
Mackpro Posted August 21, 2016 Share Posted August 21, 2016 Clusters for the newer MP engined cabs run about $1300 with the Guard Dog screen. I have soidered in buzzers on the printed circuit boards for the older 2002-2007 curved dash cabs. I haven't tried it on the newer clusters.

220cummins Posted December 14, 2016 Share Posted December 14, 2016 Newer Buzzers need the whole dash replaced and reprogrammed Quote Link to comment https://www.bigmacktrucks.com/topic/46481-cxu-low-air-and-shut-down-buzzer-not-working/#findComment-355011 Share on other sites More sharing options...
