2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 549



Diagnosis information - PDK



Solenoid valve 2 (shift cylinder selection), short circuit to ground



Diagnostic conditions



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



- The following fault is not detected: P1832



- The following fault is not detected: P183A



Possible fault causes



- Line between solenoid valve 2 and PDK control unit faulty



- Solenoid valve 2 faulty



- PDK control unit faulty



Fault setting conditions



- Internally measured current value is too high



Fault effects



- Solenoid valve power supply switch-off



- Engaged gear is held until vehicle stops



- Moving off possible in all gears



- Transmission limp-home indication in instrument cluster control unit



Setpoint Definitions



P0977



Setpoint definitions



NOTE: The specified values and value ranges correspond to the OK state in each case.



Line test setpoints



Short circuit to B+:



- Setpoint voltage -0.5 V --> +0.5 V



Short circuit to ground:



- Setpoint resistance > 0.9 MOhm



Open circuit:



- Setpoint resistance < 2 Ohm



NOTE: The specified values apply only at an ambient temperature of approx. 20 锟斤拷C (68 锟斤拷F) (room temperature).



Pressure regulator setpoints



- Internal resistance > 9 --> < 12 Ohm



Diagnosis Information - PDK (Dual-Clutch Transmission)
