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



Pressure Regulator 5 (Synchro Selection Gear: 6, R, 3, 5), Short Circuit To B+



P17A5



Diagnosis information - PDK



Pressure regulator 5 (synchro selection gear: 6, R, 3, 5), short circuit to B+



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 pressure regulator 5 and PDK control unit, short circuit to B+



- Pressure regulator 5 faulty



- PDK control unit faulty



Fault setting conditions



- Internal current measurement, pressure regulator 5: current consumption = 850 mA



Fault effects



- Pressure regulator 5 switch-off



- Engaged gear is held until vehicle stops



- Moving off possible only in 2nd gear



- Transmission limp-home indication in instrument cluster control unit



With P17AD



P17A5



Diagnosis information - PDK



Electrical pressure adjuster 5, 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
