Pressure Regulator 1 (Clutch 1), Open Circuit
P0962Diagnosis information - PDK
Pressure regulator 1 (clutch 1), open circuit
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: P1830
- The following fault is not detected: P1838
Possible fault causes
- Open circuit in line between pressure regulator 1 and PDK control unit
- Pressure regulator 1 faulty
- PDK control unit faulty
Fault setting conditions
- Internal current measurement, pressure regulator 1: current consumption = 0 mA
- Line resistance between pressure regulator 1 and PDK control unit > 1 MOhm
Fault effects
- Pressure control switch-off, clutch 1
- Clutch 1 opening
- Engaged gear is held until vehicle stops.
- Moving off possible only in 2nd gear
- Transmission limp-home indication in instrument cluster control unit
