Diagnosis information - PDK
Power supply for pressure regulators 4, 5 and 6 (system pressure and synchro selection) and solenoid valves, 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: P1752
Possible fault causes
- Line between pressure regulator 4 and PDK control unit faulty
- Line between pressure regulator 5 and PDK control unit faulty
- Line between pressure regulator 6 and PDK control unit faulty
- Line between solenoid valves and PDK control unit faulty
- Pressure regulator 4, 5 or 6 faulty
- Solenoid valves faulty
- PDK control unit faulty
Fault setting conditions
- Actual measured voltage HS3 > 4 V
Fault effects
- Power supply switch-off, pressure regulators 4, 5 and 6
- Power supply switch-off, solenoid valves
- Pressure regulators 4, 5 and 6 switch-off
- Solenoid valves switch-off
- Gear held
- White transmission limp-home indication in instrument cluster
