DME 7.8
Fault Overview Of 911 Carrera (996) As Of Model Year '02
NOTE:
- This fault code overview is for the 911 (996) Carrera as of model year 2002 and the Boxster (986) as of model year 2003.
- The turbo versions for model year 2001 and as of model year 2002 have separate fault code tables which differ in some respects from this table.
- 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.
- For Boxster (986) Tiptronic vehicles, the fault memory of the Tiptronic control unit must also be read out, because switching on of the Check Engine warning light may also have been initiated by the Tiptronic.
- After a repair, the fault memory must always be cleared.
Fault type 1: Signal implausible/implausible operating range/malfunction
Fault type 2: Open circuit/no signal
Fault type 3: Ground short/below lower limit/lean limit
Fault type 4: Short circuit to B+ /above upper limit/rich limit
*: 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
