During normal operation - brakes apply by themselves and the brake test symbol comes up on the screen. Hydraulics then disabled. Rekey and away it goes for a short while then same thing happens. It's a square little box with a circle inside and a little brake shoe on each side of the circle.
It's a symbol you can select and do a brake test while in service mode with the Cankey installed.
I have no idea why it's coming on in normal operation with NO Cankey installed?
service manual NO help as usual!
Can anyone help?
