2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 543

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 1 and PDK control unit faulty

- Solenoid valve 1 faulty

- PDK control unit faulty

Fault setting conditions

- Internal current measurement, actuator solenoid R/P: current consumption = 0 mA

- 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

P0973

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
