With P17AB
P17AB
Diagnosis information - PDK
Pressure regulator 3 (lubrication pressure/cooling pressure), 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
- The following fault is not detected: P0968
- The following fault is not detected: P0970
- The following fault is not detected: P0971
Possible fault causes
- Shunt circuit in line between pressure regulator 3 and PDK control unit
- Pressure regulator 3 faulty
- PDK control unit faulty
Fault setting conditions
- Actual pressure regulator current < setpoint current (maximum deviation = 35 mA)
Fault effects
- Power supply switch-off, pressure regulator clutch 2
- Power supply switch-off, pressure regulator for lubrication pressure
- Pressure regulator clutch 2, switch-off
- Pressure regulator lubrication pressure, switch-off
- Only gears 1, 3, 5, 7 and R are possible
- Upward limitation of cooling control pressure
- Last gear held
- Transmission limp-home indication in instrument cluster control unit
