Rubber bags have no sensors so can not log an error code. Leaks have to be deducted or found with good fashion trouble shooting. It is a common misconception that a leak is a leak. Folks often say that they parked their rig in wading mode and it doesnt lower at all... I have no leaks. Well of course it doesn't leak at wading mode, raising the rig to a height you never drive at closes the cracks that are leaking at lower heights.
Lets say you only drive at low speeds around the city. your cracks are going to develop at standard ride height. If you spend the bulk of your drive time on the freeway you cracks will develop at "motorway" height because Rovers automatically lower above XX MPH. Lowering speeds vary by model. So where ever you cracks are, they close up and seal above and below the height at which they formed.
