Hello,
Can anyone help me with ideas how to resolve a rollbar fault?
The warning light in the switch on the dash stays on, but roll bar is working fine. The fault codes from star are B1650 rollbar limit switch status unknown & deployment solenoid no resistance.
They wont clear when we tried to clear them.I have checked the limit switches(top and bottom)-they both go to earth when the bar goes up/down and signal gets to the ecu.
Deployment Solenoid has been replaced with another one,but no joy.
Please help me if you can

Can you please do?
Also forgot to mention that when I hold the rollbar switch the pump kept running and the silver "wing" behind the rear head rests was trying to go down or lock?
Do you know if this is normal?

I need an Email address to send it.

The cover you are referring to is the bow cover, I may have something on that too
