Diagnosis information - PDK
Starter interlock signal, short circuit to B+
Diagnostic conditions
2010 Porsche Cayman S (987) F6-3.4L Page 187
The control unit initially tests internal function sequences when the ignition is switched on (terminal 15). If they are OK, all diagnosable outputs are
then tested and any faults are stored.
- Ignition on
- Starter interlock active
Possible fault causes
- Line between DME control unit and PDK control unit faulty
- PDK control unit faulty
Fault setting conditions
- Starter interlock signal, voltage > 4 V
Fault effects
- Transmission limp-home indication in instrument cluster control unit
