Setpoint Definitions

P183A

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

Control unit setpoints

- Supply voltage terminal 30 9.1 V --> 16.4 V

- Voltage, terminal 15 9.5 V --> 16.0 V

Diagnosis Information - PDK (Dual-Clutch Transmission)

P183A

Diagnosis information - PDK

Power supply for pressure regulators 4, 5 and 6 (system pressure and synchro selection) and solenoid valves, short circuit to B+

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: P1752

Possible fault causes

- Line between pressure regulator 4 and PDK control unit faulty

- Line between pressure regulator 5 and PDK control unit faulty

- Line between pressure regulator 6 and PDK control unit faulty

- Line between solenoid valves and PDK control unit faulty

- Pressure regulator 4, 5 or 6 faulty

- Solenoid valves faulty

- PDK control unit faulty

Fault setting conditions

- Actual measured voltage HS3 > 4 V

Fault effects

- Power supply switch-off, pressure regulators 4, 5 and 6

- Power supply switch-off, solenoid valves

- Pressure regulators 4, 5 and 6 switch-off

- Solenoid valves switch-off

- Gear held

- White transmission limp-home indication in instrument cluster

Power Supply For P/R Actuator Solenoid, Short Circuit To Ground
