Tiptronic diagnosis 911 Carrera (996) Fault, DTC Possible causes, elimination, notes 1. CheckATFlevel(referto ServiceNo. 370235). 2. Check sensor for ATF temperature with wiring. To do this, connect an ohmmeter to control module connector pins 21 and 22. Nominalvalue: At 20 °C = approx. 1.00 kQ At 40 °C = approx. 1.15 kQ At 60 °C = approx. 1.30 kQ 3. Check wiring from control module connector pin 21 (or 22) to the 16-poletransmissionconnector pin 14 (or 13) for continuity, short circuit to ground and short to B+. 4. Check sensor for ATF temperature with transmissionwiring harness To do this, connect an ohmmeter to transmission socket pins 13 and 14. Nominalvalue: At 20 °C = approx. 1.00 k.o. At 40 °C = approx. 1.15 k.o. At 60 °C = approx. 1.30 k.o. If the nominalvalue is not OK = the transmissionwiring harness or ATF temperature sensor is defective. Note As the ATF temperature sensor is integrated in the transmissionwiring harness,the transmission wiring harness must be replaced if the sensor is damaged. 37 -D 40 37 01 Diagnosis/Troubleshooting, Tiptronic 99637D21 Printed in Germany -8, 1998
