Fault, DTC Possible causes, elimination, notes 4. Test sensor on transmission socket pins 10 and 1 with an ohmmeter. Nominalvalue: 0.80 1.2 k.Q Note The ATF pan must be removed before the sensor can be replaced. 5. If items 1 ...4 are OK and no other faults are stored, there is a mechanical/hydraulicfault in the transmission (e.g. ATF level not OK, defective converter, slipping clutches or brakes). Test point 14 Gearsel. monitor, Faulteffect: outputdrive Reduceddriving program, Signalimplausible DTC 90 The ratio of transmission input speed/transmissionoutput speed is monitored. 1. Check sensor for the transmission speed on Tiptronic control module connector pins 14 and 42 with an ohmmeter. Nominalvalue:0.80 1.2 k.Q 2. Check wiring from the control module connector pin 42 (or 14) to the 16-pole transmission connector pin 10 (or 1) for open circuit, short circuit to ground and short to B+. 3. Check shield on control module connector pin 15, 37 -D 30 37 01 Diagno~;is/Troubleshooting, Tiptronic 99637D21 Printed in Germany -8, 1998
