Diagnosis information - PDK
Solenoid valve 2, 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: P1832
- The following fault is not detected: P183A
- Solenoid valve 2 active
Possible fault causes
- Line between solenoid valve 2 and PDK control unit faulty
- Solenoid valve 2 faulty
- PDK control unit faulty
Fault setting conditions
