Isata 3 Electrical Gremlin

[M16A1VOL]

Today I attempted to extend the slide on my 2017 Isata 3 24FW and it failed. Got a Code 4 error on the switch panel. “Bad Battery.” Did not take panel off to hit reset button on switch circuit board (per manual); let the lights cycle off on their own.

Tonight I looked outside to see my LED tail lights and side markers glowing faintly. Coach and Vehicle batteries are charged. Started motor and tapped brake lights, turned headlights on and off; tailights still glowing. Front markers are not on. Code 4 error came back on on slide switch.

Any suggestions?

UPDATE - I tried clearing the minor fault code by depressing the IN / OUT buttons independently and together. NO GO.
Finally solved by connecting to shore power, removing control panel, clearing the fault code with reset button and then following instructions for resetting IN and OUT stops.

Took great care to be sure motors moved together (Hold Motor 1 and Motor 2 buttons down on back of Control Panel while pressing IN and OUT to move) and set stops. Checked to be sure slide fully extended and retracted without issue by operating several times.

Not sure WHY my rear tail light and side marker LED’s were glowing faintly except that it has been raining for two days. Started and moved the unit, turned headlights lights on and off, tapped the brakes a few times, and sprayed the trailer light connector with WD-40 to get the moisture out. LED’s went out.

Thanks!
