2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 760



- PDK control unit faulty



Fault setting conditions



- Actual pressure regulator current > setpoint current (maximum deviation = 35 mA)



Fault effects



- Power supply switch-off, pressure regulator for system pressure and synchro selection



- Power supply switch-off, solenoid valves



- Pressure regulator for system pressure and synchro selection, switch-off



- Solenoid valves switch-off



- Last gear held



- Transmission limp-home indication in instrument cluster control unit



With P17A7



P2812



Diagnostic information - PDK



Electrical pressure adjuster 7, shunt



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



- The following fault is not detected: P1842



Possible fault causes



- Shunt circuit in line between pressure regulator 7 and PDK control unit



- Pressure regulator 7 faulty



- PDK control unit faulty



Fault setting conditions



- Actual pressure regulator current > setpoint current (maximum deviation = 35 mA)



Fault effects



- Power supply switch-off, pressure regulator for system pressure and synchro selection



- Power supply switch-off, solenoid valves



- Pressure regulator for system pressure and synchro selection, switch-off



- Solenoid valves switch-off



- Last gear held



- Transmission limp-home indication in instrument cluster control unit



Setpoint Definitions



P2812



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 > 3.7 --> < 6.4 Ohm
