https://www.jlwranglerforums.com/forum/threads/“service-axle-locker-system”-light-on.13241/Lately occasionally I will be breaking for a stop and a light/warning will pop up saying "service axle locker system". Then it goes away as soon as I start moving...or just go away eveb before I start moving. Has anyone had this happen?
Did you find a solution? @grady2higMy lockers actually work though...and the light just goes on for like 10 seconds. Only happens maybe like once or twice a week.
Check the wiring going into the locker. Sounds like braking is putting stress on them.
Search; Locker position sensor potting-Dana 44. Worked for me, I found oil in the sensor and steel fuzz on sensor magnet. I drained and cleaned inside of differential and potted rear sensor, let sensor and loctite on sensor screw cure for about 45 hours filled diff. with Valvoline 75w140.. no more "ding" service axle locker message.

Yes. All it takes is oil getting into the sensor. Tazer makes a bypass that is a quick Band-Aid fix.I'm not an offroader. Would the sensor go bad if I NEVER used it? Not even once? I mean I know anything can happen, but still...
