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
