tom1642 Posted February 16, 2013 Share Posted February 16, 2013 1997 Rd 690 Intermittment Buzzer probelm. i know the kysor system uses the buzzer for low coolant, high water temp and low oil preasure and also the air preasure sensors will triger the buzzer and i have replaced with all need sensors , in my truck is 3 air preasure sensors which i have changed. i have problem with intermittment buzzer going off. i have installed new buzzer assy. appears to be 3 circuits on the buzzer. does anyone know if the buzzer controls any other circuits ? i need to try and trouble shoot this problem. seems when you move on and off the seat and also if you turn steering wheel. i have replaced every sensor new under the dash.

2stacksuperdog Posted February 16, 2013 Share Posted February 16, 2013 Those buzzers in the newer macks are used for everything, flashers, low air, oil pressure, etc. the DMV guy didn't like that one day when we got pulled over.He said they should have multiple ones instead of just one Quote Matt Link to comment Share on other sites More sharing options...
MHfred Posted February 16, 2013 Share Posted February 16, 2013 I do not have any big truck experience but my 89 MH buzzer sounds with the turn signals. You sure as hell will not see me going down the road with signal on because it is irritating as hell. Yours is not sounded from turn signals?
