Setpoint Definitions
P1734
Setpoint definitions
NOTE: The specified values and value ranges correspond to the OK state in each case.
Line test setpoints
Short circuit to B+:
- Setpoint voltage -0.5 V --> +0.5 V
Short circuit to ground:
- Setpoint resistance > 0.9 MOhm
Open circuit:
- Setpoint resistance < 2 Ohm
NOTE: The specified values apply only at an ambient temperature of approx. 20 锟斤拷C (68 锟斤拷F) (room temperature).
Displacement sensor setpoints
- Pulse-duty ratio (t / T ) > 10 % --> < 90 %
- Pulse-duty ratio, sensor faulty (t / T ) 95 %
Diagnosis Information - PDK (Dual-Clutch Transmission)
P1734
Diagnosis information - PDK
Shift rod 4 displacement sensors
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: P1706
- The following fault is not detected: P1707
Possible fault causes
- Line between displacement sensor 4 and PDK control unit faulty
- Displacement sensor module faulty
- PDK control unit faulty
Fault setting conditions
- Duty cycle of displacement sensor 4 outside valid value range (10-90 %)
Fault effects
- Pressure regulator, system pressure, switch-off
- Pressure regulator, gear selection, switch-off
- Solenoid valves for gear cylinder selection, switch-off
- No R gear
- No emergency program diagnosis
- Last gear held
- Transmission limp-home indication in instrument cluster control unit
Selector Lever Position Implausible
