Monitor Strategy Description
WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.
In case of very low temperatures it is possible that the throttle actuator is jammed by ice. The described module is used for the detection and the removing of ice between throttle flap and body. The functionality is able to detect the location of the throttle flap disturbance. We can distinguish ice in closing and opening throttle flap direction.
The ice shall be removed with a variation of the set point for the digital position controller. If the ice-breaking is not possible then the throttle position set point will be limited in lower or upper direction depends on the detected ice location.
