Brake doesn't lift on KONE monospace. The input to the brake module which Im guessing tells the module to lift the brake does not change when driving on inspection or normal and we get error 0101.
This input comes from the LCECPU board via a ribbon cable. It is labelled 24v, 0v and control. It doesnt change state when we yry to run the lift. Has anyone experienced this?

Sounds like it could be contact failure for PWM enable. 201:3 and 201:4 have contacts for that.

Could be faulty brake module, I've had to replace 2 of them.

We changed the brake module and its not that. The input to the brske module doesnt change.... the control is supposed to be grounded which enables the brake module to lift the brakes... but this input/output does not change.
