Do you get a message to raise the roll bar? It might see a problem with the release solenoid which will prevent the roll bar from deploying in an emergency. This would not affect normal raising and lowering.

Yes it says raise Rollbar it’s in red message but goes away when raised, but warning stays on in cluster …

You need a device to read the stored codes in the car's diagnostic system. SDS/Xentry, Foxwell, cReader, etc.

DIY on these cars is futile without at least a minimal code reader.

There should be at least one code. I've never really researched it, but I assume that it does some check on the release solenoid like it does on any airbag squib. It also relies on a sensor for impending roll over, so a fault there would also be a potential cause.
