Fault effects



- Engaged gear is held until vehicle stops



- Start enable only in selector-lever position P



- Transmission limp-home indication in instrument cluster control unit



Pressure Sensor 3, Short Circuit To B+



P181C



Diagnostic information - PDK

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



Possible fault causes



- Line between pressure sensor 2 and PDK control unit faulty



- Pressure sensor 2 faulty



- PDK control unit faulty



Fault setting conditions



- Pressure sensor 3, signal > 4.5 V
