In the case of vehicles with ASC+T or DSC, the system must be deactivated with the switch. The ASC+T or DSC telltale and warning light must light up in the instrument cluster!
The brakes must be at normal operating temperature. For this purpose, gently warm up the brake discs/drums while dry by braking the vehicle several times.

You must follow without fail the guidelines contained in the operating instructions of the relevant test stand manufacturer.
Failure to do so may result in damage to the vehicle and the system and also personal injury.
