Was bedeutet der Fehlercode?
The transmission control module reads the signal from the lock-up pressure switch (PS4) and uses it to check the position of the lock-up valve. The fault means the signal is wrong, because the lock-up solenoid has jammed in either the open or the closed position.
Mögliche Ursachen
- The lock-up pressure switch is stuck
- Contact resistance in the connections
Was Sie tun können
- 1Read off the fault codes and deal with any other transmission fault codes first
- 2Have a workshop program the control module with the latest software, since the module needs the updated version
- 3After programming, read the fault codes again; if codes for the pressure switch or lock-up solenoid remain, they should be followed up
- 4Road test the car and see whether the fault code comes back
Symptome, die Sie bemerken können3
- The automatic transmission warning lamp flashes
- No lock-up function
- Harsh gear shifting
