2 - Solenoid Valve, 1-2/4-5 Gearshift

P0753

2 Solenoid Valve, 1-2/4-5 Gearshift

Faults in the wiring, connectors, output stage and the valve should be detected.


NOTE: The redundancy transistor is switched off. The setpoint values of the current regulator are set to 0 and all change-over valves are switched off. The control module is then in emergency operation. Minimal cycle is additionally activated.


Diagnosis conditions
- Ignition on
- Redundancy transistor on
- Solenoid valve on
- Short circuit to ground/Voltage or interruption of the output stage

Possible fault cause
- Connection to Tiptronic control module faulty
- Solenoid valve, 1-2/4-5 gearshift faulty
- Control module faulty

Affected terminals
- Terminal 14

Diagnosis/troubleshooting

NOTE: If the fault codes 2 (P0753) solenoid 1-2/4-5 shift, 3 (P0758) solenoid valve 2-3 shift, 4 (P0763) solenoid valve 3-4 shift and 5 (P0743) torque converter solenoid valve are displayed together, an open circuit in the circuit to the control module terminal 38 may be present.
