Was bedeutet der Fehlercode?

The transmission control module receives a signal from the lock-up pressure switch (PS4) to check the position of the lock-up valve. The fault indicates the lock-up solenoid is jammed open, based on the pressure switch reading.

Mögliche Ursachen

The lock-up pressure switch is stuck
Contact resistance in the connections
The transmission oil level is too high
Mechanical fault in the transmission control system
Electrical fault in the pressure sensor circuit

Was Sie tun können

1Read off the fault codes and deal with any other transmission fault codes first
2Check the transmission oil level; a level that is too high can cause the fault, so if the level is wrong a workshop should correct it
3Use a multimeter to check that the wires to the pressure switch have no open circuit and are not shorted to ground
4Have a workshop check the connectors to the transmission and the pressure switch module for contact resistance and oxidation, and check the oil filter for particles
5If the fault remains after these checks the pressure switch module may need replacing; a workshop does this

Symptome, die Sie bemerken können3

General orange warning lamp on
No lock-up function
Harsh gear shifting

Was der Fehler beeinflussen kann3

The Emergency mode II program is activated
The line pressure is not reduced when shifting or when the gear selector is moved between P-R, N-R and N-D
No torque limiting request is sent to the engine control module when shifting
