DME 7.8 DME 7.8 0 0-PFUEB01TFault overview of 911 (996) Turbo model year 2001 only Note! ♦Please note: This fault code overview only applies to the 911 (996) Turbo model year 2001. ♦For the Turbo as of model year 2002, some fault codes have been renamed in order to implement the changed standards of the Californian environmental agency. ♦The model year allocation refers to the program and data status in the DME control module. • To be certain that a fault is no longer present after a repair or clearing of the fault memory, a short test or test drive should be carried out. This is the only way of ensuring that all diagnosis routines of the DME control module have been performed. • In the case of Tiptronic faults, the fault memory of the Tiptronic must also be read out for diagnosis/troubleshooting. • After a repair, the fault memory must always be cleared. Fault type Signal implausible/implausible operating range/mal- 1: function Fault type Open circuit/no signal 2: Fault type Ground short/below lower limit/lean limit 3: Fault type Short circuit to B+ /above upper limit/rich limit 4: *: In the case of misfire faults, the fault types have a different meaning. Fault type 1: Emission-related fault after starting Fault type 3: Emission-related fault during journey Fault type 4: Fault damaging to catalytic converter **: In the case of oxygen sensor faults, the fault types have a different meaning. Fault type 1: All electrical faults (open circuit, short circuit to B+ or ground) cause this fault output Fault type 2: Interference from the oxygen sensor heater in the sensor signal Fault type 3: Oxygen sensor aging fault, sensor dynamic response Fault type 4: Oxygen sensor aging fault, sensor contamination and shift of characteristic Fault overview of 911 (996) Turbo model year 2001 only 0-PFUEB01T page 1 Printed in Germany – 14, 2003 fue_dm78
