14 Gear selector mechanism tiptronic signal The information on selector lever in tiptronic gate, selector lever in Tip+ or selector lever in Tip- is transmitted to the gearbox control unit in the form of a frequency-modulated square-wave signal (FMR signal) along a discrete line (see DSO images). Advantages of this new feature: – Higher operational reliability - only one line is required to the control unit (instead of three), hence there are fewer potential sources of fault. – Better self-diagnostics. Reference For further information on the tiptronic signal and the tiptronic switch F189, please refer to SSP 291, from p. 50). Apart from the different signal waveform, the selector mechanism has the same basic funtion as the selector mechanism used in the <strong>Audi</strong> A3‘04. The signals and from to the gear selector mechanism can be tested by using test adapter V.A.G. 1598/54 in combination with test box V.A.G. 1598/42. The signals to and from 09D gearbox can be tested by using test adapter V.A.G. 1598/48 in combination with test box V.A.G. 1598/42. The signals to and from the 0AT gearbox can be tested by using test adapter V.A.G. 1598/40 in combination with test box V.A.G. 1598/14.
