Abstract:
1. A method for diagnosing a position detector, which position detector is used in determining the position of a control means, which position detector comprises a resistance track having first and second ends, a first terminal in connection with the first end of the resistance track, a second terminal in connection with the second end of the resistance track, a slide means electrically connected to the resistance track, wherein the slide means is arranged to move in relation to the resistance track by effect of a change in the position of the control means, a slide terminal in connection with the slide means, an electricity supply, a voltage measuring means, and a signal processing unit for diagnosing measurement data, the method comprising: receiving a supply voltage in the slide terminal; measuring a first output voltage of the first terminal; measuring a second output voltage of the second terminal; and providing at least the measured first output voltage and the measured second output voltage for the signal processing unit.
