P173C
Diagnosis information - PDK
Transmission input shaft speed sensor, clutch 2, short circuit to ground or 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: P1824
- The following fault is not detected: P1825
Possible fault causes
- Line between speed sensor 2 and PDK control unit faulty
- Speed sensor for clutch 2 faulty
- PDK control unit faulty
Fault setting conditions
- Sensor voltage < threshold value (< 0.15 V)
Fault effects
- Electrical substitute value
- No gear preselection
- No R gear
- Transmission limp-home indication in instrument cluster control unit
Setpoint Definitions
P173C
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).
Speed sensor setpoints, transmission input shaft
Speed sensor, transmission input shaft: Setpoint current > 3 --> < 20 mA
