M925 low air warning wonky

[charlietango]

Sometimes the low air warning lights work, sometimes they don't. The audible sound always works though, however sometimes I can hear it faint while driving down the road...I stop pull the Ebrake and let it off - sound is gone. then I can hear it sneaking back on ever so quietly. Any one have this experience with a bad unit? Also ABS light stopped turning off on start-up routine. Warm weather welcomes me back...here have some phantom truck problems that didn't exist before winter ! lol


Cheers guys. Hope you've all been well

There is a module under the dash. First thing I would check is the ground and make sure the connector is on good. They have been known to go bad though.
