Was bedeutet der Fehlercode?

The control module reads the lock-up pressure switch (PS4), which shows where the lock-up valve sits. The fault indicates the lock-up solenoid is jammed closed, based on that signal, so the lock-up function cannot be engaged.

Mögliche Ursachen

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

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
4Have a workshop check the connectors to the control module and the transmission for contact resistance and oxidation, and replace the oil filter if needed
5If the fault remains, the control module or the pressure switch module may need replacing; a workshop does this

Symptome, die Sie bemerken können3

General orange warning lamp on

Was der Fehler beeinflussen kann3

The Emergency mode II program is activated
Line pressure is not reduced when gears are engaged or when the gear selector is moved between P-R, N-R and N-D
